Qolsys IQ Hardwire 16-F w/ Large Enclosure Posts

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.

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.

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.
