Qolsys IQ Hardwire 16-F Posts

Alarm Grid is excited to announce we are now offering certain Qolsys products at a lower price. Price reductions occur from time to time, and we're always happy to pass those savings on to our customers. The products we'll be talking about today cover a wide range of uses. Let's take a look.

The Qolsys Hardwire 16-F: This wired to wireless translator for 319.5 MHz panels sets the Gold Standard for these types of devices. With support for up to 16 wired zones, including one 2-wire smoke zone with up to ten (10) smoke detectors, 500 mA of power for devices such as motion detectors, and a 500 mA siren relay compatible with panels on RF PIC Version 11.1.4.G2 or higher. The Qolsys Hardwire 16-F is one of the most versatile expansion modules we've ever seen.

Qolsys IQ Carbon: The Qolsys IQ Carbon transmits at 319.5 MHz and is compatible with the Qolsys IQ Panel 2 and Qolsys IQ Panel 2 Plus as well as older Interlogix/GE Simon panels. The Qolsys IQ Panel 2 and IQ Panel 2 Plus come in several different varieties, so be sure your panel supports 319.5 MHz wireless sensors before purchasing the Qolsys IQ Carbon. These panels customarily come in a box with a gold edge.

The IQ Carbon should be used in homes with a high chance of Carbon Monoxide gas build-up. CO gas is odorless and colorless, and is formed whenever carbon-based fuels are not burned efficiently. Carbon-based fuels include coal, oil, natural gas, and even wood. Homes with gas furnaces, gas appliances, fireplaces or portable gas heaters should definitely have properly placed Carbon Monoxide detectors.

Qolsys IQ Dimmer: The Qolsys IQ Dimmer is a Z-Wave plug-in on/off dim capable lamp module. It supports 120VAC/60 Hz and operates at 908.42 MHz, the Z-Wave frequency used in the United States. It can support the equivalent of 2.5A, 300W incandescent, 65W dimmable CFL/LED. If you plan to use this device for dimming, be sure that the bulb being used also supports light dimming. Although this is a standard Z-Wave device, rather than Z-Wave plus, it might be useful in a location where you need to add a device where you aren't concerned with range, and you know that the device won't need to act as a repeater. Although this device WILL repeat Z-Wave signals, it will do us using standard Z-Wave limitations.

Qolsys IQ Siren: The Qolsys IQ Siren uses standard Z-Wave technology, allowing a user to easily add a remote siren that produces up to 105dB siren sounds. This device plugs into any standard outlet. It is then paired with the alarm panel. On Qolsys panels, that's all you have to do. Once the siren is paired as a Z-Wave device, it will automatically follow the alarm sounds from the panel by default. The IQ Siren can also be used on other Z-Wave compatible panels, but may require additional programming in order to sound upon alarms on those panels.

Qolsys Image Sensor: The image sensor is a motion sensor with a still camera built-in. This affordable device just got even more affordable! For situations where you want to be able to see what's going on, but you don't want to add a full video system, the Qolsys Image Sensor is perfect. In conjunction with Alarm.com and the right monitoring plan, you can use the Image Sensor to peek-in and see what's going on at your home or business. You can set it up so that you receive an image capture upon the panel being disarmed, or when motion is detected in an area after a long period of inactivity. It's great for making sure the kids got home from school safely, or just to check in on your dog or cat who may be home alone.

Qolsys recently released a service bulletin describing an issue with certain IQ Hardwire 16-F units. This issue affects both the small enclosure and large enclosure versions. Under certain circumstances, affected units can signal a false tamper/tamper restore message for connected zones.

Qolsys TSB #210708, which was released on July 8, 2021, describes this issue, and the corrective action Qolsys is taking to remedy the problem. They do not provide a lot of information regarding what "conditions" bring about this behavior. We have asked for more detail, and if more information is forthcoming, we will provide updates here in our blog.

Rest assured that only a certain number of these devices are affected, and we will provide users with the necessary information to determine if they have one of these units. Qolsys IQ Hardwire 16-F units that were manufactured outside of the window in question are not affected and should not exhibit this behavior.

How to determine if your Qolsys IQ Hardwire 16-F small enclosure (SKU: QS7133-840) is affected:

On the unit itself, or on the box that the unit came in, check the Revision Sticker. This will appear as a bar code on the sticker and will be marked with SN: and DL: If the 4th character of the SN, moving from left to right, is a "C" then the Qolsys IQ Hardwire 16-F small enclosure should be returned/replaced. This sticker may be found on the rear of the unit and may require that you dismount the unit from the wall to get access it.

How to determine if your Qolsys IQ Hardwire 16-F large enclosure (SKU: QS7134-840) is affected:

On the Qolsys IQ Hardwire 16-F large enclosure, the way you determine the revision is the same, but the revision information is different. On these units the revision to be on the lookout for is "B" rather than "C". This sticker should also appear on the unit itself as well as on the box that the unit comes in. Since these devices come from the factory with an enclosure, the sticker may be on the enclosure rather than the printed circuit board. Unfortunately, it may also be on the back of the enclosure, requiring that it be removed from the wall to be accessed. When reading the sticker, the 4th character when viewing the SN from left to right is "B" on affected units. See the example below:

Qolsys has pulled back available affected stock to correct this issue. Units that may have been affected, but have since been pulled back into manufacturing and reworked or replaced, will sport a sticker that says "TEST OK".

If you purchase a Qolsys IQ Hardwire 16-F that falls within the Revision range discussed above, but the item has a "TEST OK" sticker affixed somewhere on the packaging or the unit itself, then you do not have to worry about this issue. If you purchased a Qolsys IQ Hardwire 16-F prior to the date that this notice was released, and your device falls within the revision range discussed above, then you should contact your distributor to discuss replacing the unit. Per Qolsys, you should do this even if you haven't observed the behavior described in this Technical Service Bulletin.

If you are an Alarm Grid customer, and you purchased an affected unit from Alarm Grid, you can contact us at support@alarmgrid.com. We are here Monday - Friday from 9am to 8pm ET. If you prefer to speak to us by phone, you can reach us at 888-818-7728. It is our pleasure to assist you with any and all of your alarm needs. Stay safe!

Do you want to achieve a hybrid security system that uses both wireless and hardwired wired sensors? We have the perfect solution for you in the Qolsys IQ Panel 2 Plus and the Qolsys IQ Hardwire 16-F. This will let you use both wired sensors and wireless sensors with one convenient system!

Although we are well into the age of wireless security systems, there is still a place for hardwired sensors. Many people install wired sensors for new construction as a way of fully integrating their security system with their home or office. This is a great way to increase property value, and it's a fairly simple task for a builder to accomplish.

In addition, hardwired sensors require less maintenance than wireless sensors. They do not need any battery replacements, and many do not draw any electricity from a panel or wired to wireless converter module. Also, more and more alarm system manufacturers are offering ways to integrate hardwired sensors in with wireless panels. Using wired and wireless sensors together on the same system is sometimes referred to as a "hybrid security system".

The advantage to using a hybrid alarm system with both wired and wireless sensors is that you can still integrate your wired sensors in with the building, while also being able to easily add wireless sensors when convenient. It can be challenging to run wire for hardwired sensors after a building has been constructed. If you need to add some quick new sensors, then wireless ones make for a great selection. They are super easy to install, and they are just as reliable as wired sensors. Also, there are many sensors out there that are only available in wireless varieties.

The 319.5 MHz IQ Panel 2 Plus is a great option for those looking to set up a hybrid security system, as it readily supports DSC PowerG Security Sensors and has a great wired to wireless converter option in the Qolsys IQ Hardwire 16-F. If you aren't familiar with PowerG Sensors, they offer some of the best range in the industry, as they can be used from up to 2,000 feet away from the IQ Panel 2 Plus. The PowerG Sensors are also extremely secure, since they utilize 128-bit AES encryption and Frequency Hopping Spread Spectrum (FHSS) Technology. These are some of the best wireless sensors that you can possibly use with a security system.

But how do you integrate wired sensors in with your new Qolsys IQ Panel 2 Plus System? That's where the Qolsys IQ Hardwire 16-F comes in. This is a wired to wireless converter module that is specifically designed for use with 319.5 MHz security systems. Hardwired sensors connect directly with the Qolsys IQ Hardwire 16-F, and the module sends out a wireless 319.5 MHz signal to the panel on their behalf. This will allow the connected wired sensors to interface with a wireless alarm system that otherwise wouldn't accept them.

There are two (2) versions of the Qolsys IQ Hardwire 16-F. There is a Qolsys IQ Hardwire 16-F w/ Small Enclosure and a Qolsys IQ Hardwire 16-F w/ Large Enclosure. The difference between these two is that the large enclosure module will come with a large plastic cabinet designed for housing multiple IQ Hardwire 16-F units in one convenient location. If you are only bringing over a few hardwired sensors and only need one converter unit, the the small enclosure will often suffice. But if you are using multiple converter modules, then you may want to house them in an enclosure.

Note that every IQ Hardwire 16-F supports up to 16 hardwired zones, including one zone for 2-wire smoke detectors. Also note that each large enclosure from Qolsys is designed to support up to two (2) sets of IQ Hardwire 16-F Converters. Backup batteries are not included, but they are highly recommended. These two sets of batteries will also fit in the large enclosure with the converters.

Both the 319.5 MHz IQ Panel 2 Plus and both versions of the IQ Hardwire 16-F are available for purchase on our website. Please make sure you are using the 319.5 MHz IQ Panel 2 Plus, as the IQ Hardwire 16-F will not work with the other versions. However, the IQ Hardwire 16-F can work with the original non-Plus Qolsys IQ Panel 2. And if you have a 345 MHz IQ Panel 2 Plus, then you can achieve similar results with the Honeywell 5800C2W. Before you know it, you will have an effective and reliable hybrid alarm system!

If you have any questions about using the Qolsys IQ Panel 2 Plus with a Qolsys IQ Hardwire 16-F, or if you want to learn more about hybrid security systems in general, please email us at support@alarmgrid.com. Our support team is available from 9am to 8pm ET M-F. We look forward to hearing from you!

Like most modules that use end of line resistors for zone monitoring, the IQ Hardwire 16-F is no exception. It comes standard with 4.7k resistors, or it can support end of line resistor (EOLR) learning for values ranging from 1k to 10k. But the standard 4.7k resistors have five (5) bands.

The Qolsys IQ Hardwire 16-F is 319.5 MHz wired to wireless converter. It allows you to easily convert a wired system into a wireless system by taking over your existing hardwired sensors. The hardwired sensors will connect directly with the the IQ Hardwire 16-F module, and the converter will send 319.5 MHz wireless signals on their behalf. The system will then treat these hardwired sensors as wireless zones. You just need to make sure that you have enough wireless zones on the system itself. Each Hardwire 16-F module adds support for 16 additional hardwired zones.

If you aren't familiar with end of line resistors, they are small jumpers that are wired-in at the end of line of zones. The purpose of a resistor is to let the system know that a zone has been physically cut. If someone cuts or tampers with a hardwired zone that is configured with an EOLR, then a short will occur. This will result in a trouble condition on the system. If your system is currently in an armed state, this will cause an alarm. A shorted zone while the system is disarmed will just lead to loss of supervision for the sensor.

You must use an EOLR at each zone for the Qolsys IQ Hardwire 16-F, including with zones that do not have a connected sensor and are not actively being used. Any unit manufactured before week 40 of 2019 was required to use 4.7k resistors at all 16 zones. But from week 40 of 2019 and onward, Qolsys began manufacturing units that support end of line resistor learning. These newer units support Legacy Mode (where 1k to 10k resistors can be used) and UL Fire Mode (where 4.7k resistors must be used at every zone). For information on switching between the two (2) resistor modes, please see this FAQ.

What's somewhat unique about the 4.7k resistors included with the Qolsys IQ Hardwire 16-F is that they use five (5) bands instead of four (bands) like we mostly encounter. The 5-band resistors for the Hardwire 16-F are Yellow-Violet-Black-Brown-Brown. This equates to a 4.7k ohm resistor with a tolerance of +/- 1%. This differs from the four (4) band 4.7 k resistors that we often see, which are Yellow-Violet-Red-Gold. Those four (4) band resistors offer a tolerance of +/- 5%.

Really, there is no difference in the way you install these resistors. But it can be good to know if you are setting up a a Qolsys IQ Hardwire 16-F device. It is advised that you connect the resistors and sensors before attempting to enroll the module with the panel. We also recommend clearing the memory through a factory default for module before enrollment. More information can be found here.

If you have any questions about the Qolsys IQ Hardwire 16-F or any of our other products, or if you want to learn more about our monitoring services. Please reach out to us by emailing support@alarmgrid.com. We operate support hours from 9am to 8pm ET M-F. We look forward to hearing from you!

Qolsys is the first manufacturer to make a big splash in the new year with their IQ Hardwire 16-F w/ Large Enclosure, also known as the QS7134-840. This product includes a Qolsys IQ Hardwire 16-F Wired to Wireless Converter and a large plastic enclosure for housing up to two (2) 16-F units.

If you aren't already familiar with the Qolsys IQ Hardwire 16-F, it is a wired to wireless converter module that allows you to use hardwired sensors with a compatible 319.5 MHz wireless system. This is fantastic if you have an existing hardwired system, and you want to upgrade to a newer wireless panel. The IQ Hardwire 16-F module features 16 zone terminal pairs for adding up to 16 wireless zones to a compatible panel.

Compatible wireless systems for the Qolsys IQ Hardwire 16-F include the original Qolsys IQ Panel 2 and the Qolsys IQ Panel 2 Plus w/ 319.5 MHz Daughtercard. The module utilizes S-Line Rolling Code Encryption when paired with the Qolsys IQ2 or IQ2+. If paired with a different 319.5 MHz system, then the IQ Hardwire 16-F will not utilize any encryption. We made a nice introduction post on the 16-F module when it was released last year.

But the Qolsys IQ Hardwire 16-F does more than just provide wired sensor support. It can also function as an automatic wireless siren relay for a compatible IQ Panel 2 or IQ Panel 2 Plus System. More information on this function can be found here. The module is also noteworthy for its ability to support 2-wire smoke detectors on Zone 16. More information on using 2-wire smoke detectors with the Qolsys IQ Hardwire 16-F can be found in this FAQ.

Qolsys made one noteworthy change to the QS7134-840 when compared with the initial IQ Hardwire 16-F modules (known as QS7133-840). The new QS7134-840 can use a "Legacy Mode" to calibrate 1k to 10k resistors wired in parallel (NO) or series (NC). The original QS7133-840 could not perform this calibration, and it was restricted to only supporting 4.7k resistors. As a result, the new QS7134-840 has greater flexibility in its installation as far as choosing resistors is concerned.

You must have a resistor on each zone of the IQ Hardwire 16-F. This is true regardless of whether it is an original or an updated 16-F module, and regardless of whether or not all the zones on the module are used. All zones need a resistor. Anyone who orders the new IQ Hardwire 16-F w/ Large Enclosure will receive the new QS7134-840 module that supports calibration. That said, it is usually just easiest to use the 4.7k resistors that comes included with all versions of the IQ Hardwire 16-F. More information on installing the Hardwire 16-F can be found in this comprehensive FAQ.

Of course, the most exciting addition to the Qolsys QS7134-840 is the large plastic enclosure that can house up to two (2) Qolsys IQ Hardwire 16-F Converters and their respective backup batteries. This is perfect for making your wiring nice and organized and having everything neatly contained. We know that some DIYers out there love to make their wiring super neat and organized, and now they have their chance! We were particularly impressed with the wiring images Qolsys put out.

For reference, the large plastic enclosure measures 16"L x 14"W x 3"D. Even though it can house two (2) 16-F modules, only one (1) 16-F module is included with each QS7134-840 order. If you want a second module, then you should just order an additional individual module without the large plastic enclosure. You must also remember to buy one (1) backup battery for each 16-F converter module you use. Either the UltraTech 1240 or UltraTech 1270 will work for this purpose. Each module comes with a battery harness for connecting a backup battery. One final accessory that you might want to obtain is a cam lock for securing the large plastic enclosure. We are currently working with Qolsys to determine the best possible cam lock for the job. We will update once we find out.

If you have any questions about the Qolsys QS7134-840 IQ Hardwire 16-F w/ Large Plastic Enclosure or any of the other products on our website, or if you want to learn more about our monitoring services, please reach out to us! The best way to contact us is to email support@alarmgrid.com. We operate our support hours from 9am to 8pm ET M-F. We look forward to hearing from you!

Hey Alarm Grid fans! We're here with another video recap! Our video team worked with Jorge last week to put together three (3) new videos before the Thanksgiving break. This time Qolsys equipment is featured. Let's check out the newest instructional videos from Jorge and Alarm Grid.

What is the Qolsys Hardwire 16-S?

Jorge provides an overview of the Qolsys IQ Hardwire 16-S. This is a wired to wireless converter that works with wireless security systems that operate at 319.5 MHz. You connect hardwired sensors to the IQ Hardwire 16-S module so that the module can send wireless signals to the panel on their behalf. This is great for using hardwired sensors with a system that otherwise wouldn't support them. A great system to use with the IQ Hardwire 16-S is the original IQ Panel 2. You can also use it with an IQ Panel 2 Plus w/ 319.5 MHz daughtercard.

Overview: The Qolsys Hardwire 16-F

Jorge teaches users about the Qolsys IQ Hardwire 16-F. This wired to wireless converter is just like the Qolsys IQ Hardwire 16-S, except that the Qolsys Hardwire 16-F adds the ability to support 2-wire smoke detectors at Zone 16. This is a great feature, as most wired to wireless converters will not support life-safety sensors. When the IQ Hardwire 16-F is used with a compatible IQ Panel 2 System, the panel will know to send a reset signal to the converter when a fire alarm is cleared. This will reset the smoke detector and stop it from sounding.

Programming a Qolsys IQ Panel 2 Alarm System

Jorge covers the process for programming a Qolsys IQ Panel 2 System. The Qolsys IQ Panel 2 is known for being one of the easiest systems to program. It is ideal for DIYers and people who are new to alarm monitoring. Wireless sensors can be auto-enrolled to the 128 available wireless zones on the panel. The menus are very simple to navigate using the panel's 7-inch touchscreen controller. And if you are using a Qolsys IQ Panel 2 Plus, then you can use PowerG Sensors. These sensors offer some of the best range and security in the industry!

Hi DIYers! Today, we're taking a look at why one-go-all-go smoke detectors can help ensure that everyone in the building is alerted during a fire. Simply put, a one-go-all-go smoke detector will cause all of the other compatible smoke detectors on the system to activate at the same time.

Having all the smokes in your home activate at the same time can be crucial for ensuring that everyone is alerted in the event of a fire. This is especially true for larger homes that need several smoke detectors for complete coverage. Most alarm systems can have some type of interconnected one-go-all-go smoke detector network. However, implementing this feature properly can be difficult, and it requires additional equipment and wiring. Another important thing to remember is that the one-go-all-go feature is best achieved by using the same detector model across the network.

For those with wired alarm control panels, there is often a way to achieve a one-go-all-go setup using hardwired smokes. This is possible with both 2-wire smokes and 4-wire smokes, but both require the proper equipment. Many wired panels offer a way to conveniently reset the zone used for 2-wire smokes after a fire alarm has been cleared. This is needed for getting the smoke detectors to stop sounding and to reset the detector so that it can trip again, if necessary.

For the Honeywell VISTA Panels, all 2-wire smokes must go on zone 1. This zone will automatically reset, and power will be briefly dropped to the smokes after the alarm is cleared. Multiple 2-wire smokes are wired together in parallel, with an end of line resistor (EOLR) for wiring supervision. A good 2-wire smoke detector to use is the System Sensor 2WTA-B, which also includes a built-in sounder.

Unlike 2-wire smokes, 4-wire smokes have less restriction regarding where they can be wired. In fact, a 4-wire smoke on a Honeywell VISTA System will generally go on any hardwired zone, except for zone 1. Again, the smokes can be configured for a one-go-all-go setup, but this will require additional equipment and wiring. This also allows the smokes to take up fewer systems zones, as they can all use the same zone and programming settings.

One downside to using 4-wire smokes is that they often require additional resources to work properly. In order to get a 4-wire smoke to stop sounding, power to the device must be dropped. But unless the system has a built-in relay, this cannot be done without additional hardware. This can require an external relay, and possibly an additional power supply as well. Proper operation will also require an end-of-line power supervision relay to check whether or not power to the smokes has been interrupted. If you do decide to go the 4-wire route, the System Sensor 4WTA-B is a good option.

More recently, certain wireless smoke detectors also offer one-go-all-go functionality. Honeywell really took the initiative here by making their Lyric SiXSMOKE Sensor a one-go-all-go device. This sensor is exclusively compatible with the Honeywell Lyric Alarm System, and provides a very easy way to achieve a robust one-go-all-go setup. One-go-all-go is also compatible with the new Honeywell SiXCOMBO, which also offers heat and CO detection.

If you have a different wireless system than the Lyric, then there might still be way to attain a one-go-all-go setup. In most cases, this will require using 4-wire smokes with a compatible wireless transmitter. The transmitter will need to be able to support Normally Open (NO) life-safety devices with an end of line resistor. However, this is not possible for every wired-to-wireless converter.

Additionally the standard equipment for any 4-wire smoke is also required. This includes a relay, power supply and resistor. One transmitter that will work for this application is the Honeywell 5817CBXT. This module is part of the Honeywell 5800 Series, and it will work with nearly any alarm system that accepts the 345 MHz wireless frequency. Remember, the transmitter or converter must communicate at a frequency accepted by the alarm control panel.

Additionally, Qolsys recently released the Qolsys IQ Hardwire 16-F for 319.5 MHz systems. This is a 16-zone wired to wireless converter that is great for bringing over hardwired sensors to a newer wireless system. Zone 16 on the module is a Normally Open loop specifically designed for 2-wire smokes. The loop will support up to ten 2-wire smoke devices, which are wired in parallel with an end-of-line resistor. This revolutionary module represents the first way to bring 2-wire smokes over to a wireless all-in-one system. The necessary resistors come included with the module.

Additionally, if you have an existing network of high-voltage smokes, you can integrate them into a wireless system using a takeover module. These are devices that listen for the unique temporal sound of an activated smoke detector. If the existing smoke detector network is one-go-all-go, a single takeover module can accommodate the entire network. Alarm Grid offers takeover modules that operate at the 319.5 MHz (Interlogix/GE and Qolsys), 345 MHz (Honeywell and 2GIG) and 433 MHz (DSC) wireless frequencies. That way, you can conveniently take an exiting high-voltage smoke network and start using it with your new wireless security system!

If you need help choosing smoke detectors for a one-go-all-go setup, please don't hesitate to reach out to us! We can help you determine the perfect fire-protection devices for your security system. You can send an email to support@alarmgrid.com, or you can call us at (888) 818-7728 during our normal business hours of 9am to 8pm EST M-F. We look forward to hearing from you!

Hi DIYers! We are very excited to announce that Qolsys has released the Qolsys IQ Hardwire 16-F Wired to Wireless Converter. This module replaces the IQ Hardwire 16-S, and it adds the ability to use 2-wire smokes with a compatible wireless system. It features 16 hardwired zone terminals.

The Qolsys IQ Hardwire 16-F works similar to any wired to wireless converter module. The hardwired sensors will connect directly with the 16-F converter. The converter will then send out a wireless 319.5 MHz signal to communicate with compatible alarm systems. This makes the IQ Hardwire 16-F perfect for users of old hardwired systems who want to upgrade to a newer wireless system. The user will be able to bring all of their old hardwired security sensors to their new system.

The 319.5 MHz signal makes the 16-F compatible with many great systems. These include the Qolsys IQ Panel 2, the Qolsys IQ Panel 2 Plus with 319.5 MHz Daughtercard, the original IQ Panel and the Interlogix Simon Series Systems. The module will use rolling code encryption when communicating with the IQ2 and IQ2+ Systems. However, the signals will not be encrypted when used with other systems. Please keep frequency compatibilities in mind when purchasing a wired to wireless converter. If you have a 345 MHz system, a Honeywell 5800C2W will work instead. However, that module will not support 2-wire smokes.

The first 15 zone terminals on the IQ Hardwire 16-F are for Normally Open or Normally Closed hardwired security sensors. But the support for 2-wire smokes is what really helps the IQ Hardwire 16-F stand out from other converters. The 16th zone on the module is specifically designed for Normally Open 2-wire smoke detectors. This versatile zone is capable of supporting up to ten 2-wire smoke detectors when they are wired in parallel. Please note that 4-wire smokes and carbon monoxide sensors cannot be used with the IQ Hardwire 16-F.

Alternatively, the zone can also be used with any Normally Open sensor if the user would prefer that instead. Each zone requires a 4.7k resistor wired in parallel (NO) or series (NC). This is true even if the zone is not used. All of the necessary resistors come included with the device. Note that the included resistors are color-coded Yellow-Violet-Black-Brown- Brown. This can be helpful to know if you ever need to find replacement resistors.

The Qolsys IQ Hardwire 16-F is available for purchase now from the Alarm Grid website. This is a great module for anyone upgrading from an older hardwired system to a new Qolsys IQ Panel 2 or IQ Panel 2 Plus. Get the Qolsys IQ Hardwire 16-F now!
