FortrezZ is discontinuing another of its Z-Wave products due to its inability to source some required components. For this reason, Alarm.com no longer recommends its installation. Installed units will continue to work, and Alarm.com will continue to offer troubleshooting support for them.

This may be the result of the supply chain issues experienced a few years ago. FortrezZ was forced to discontinue the MIMOlite some time ago, and now we're seeing the discontinuation of their Water Valve. Products already purchased and/or installed are not affected by this news.

If you already have a FortrezZ Water Valve (WV-01) but haven't installed it yet, no worries. It should still install and operate as expected. If you have any problems related to integrating the water valve with Alarm.com, you can still get assistance from tech support. If you are an Alarm Grid monitoring customer, we offer free technical support as well.

If you were thinking of purchasing a FortrezZ Water Valve, but missed the opportunity, you have other options available. We offer the Alarm.com Z-Wave Plus Smart Water Valve and Meter, and the Alarm.com Z-Wave Plus Smart Water Valve. The Alarm.com smart water valves use Z-Wave Plus and can be used with any Alarm.com compatible panel that supports Z-Wave or Z-Wave Plus.

In addition to the Alarm.com options, we also offer the Qolsys IQ Water Valve. It's available in two (2) separate kits. The PowerG Kit offers the IQ Water Valve with two (2) DSC PG9985 Flood Sensors. The S-Line Kit offers the water valve with three (3) Qolsys IQ Flood-S 319.5 MHz S-Line Flood Sensors. If purchasing one of these kits, be sure to take into account what panel the kit is meant to work with. All Qolsys IQ Panel 4 versions can support PowerG while only some can support 319.5 MHz S-Line sensors.

A smart water valve is most advantageous when used in conjunction with flood sensors. If a water leak is detected by a sensor, it can alert the alarm system. Then, the system can use that information to run a rule or scene to automatically shut off the water main to the home or business. Having this type of protection can save on homeowner's insurance premiums, and can prevent widespread damage and loss to your home or business.

Qolsys recently released a Technical Service Bulletin outlining an issue with the IQ2 and IQ2+ panels and PowerG sensors. In some cases, panels that have just installed either firmware version, or panels running these versions that are rebooted, may lose touch with existing PowerG sensors.

The problem, according to Qolsys, is the encryption key. In some rare cases, either during the reboot after the firmware update, or upon rebooting once the firmware update has been applied, the panel's encryption key can be set back to default. Once this occurs, any PowerG devices in the field that have been programmed into the panel will no longer be able to communicate successfully with the panel.

When this situation occurs, a previously working PowerG device will show status on the panel, and on Alarm.com if monitored, of "Not Networked". It may also show an "!" next to the zone's status on the panel's Home Screen. If this condition is allowed to continue for the full supervisory window of the sensor (24-hours for non-life safety sensors, 4-hours for life safety sensors by default) then each affected sensor will go into supervisory failure at the panel and will show a status of Malfunction when viewed through Alarm.com.

If you see this issue on your Qolsys IQ Panel 2 or IQ Panel 2 plus system, you'll need to delete ALL PowerG sensors from the panel, and then re-learn them from scratch. By doing so, a new encryption key will be created and shared with each PowerG device. Once this has been done, all devices should begin working normally again. PowerG devices should be reprogrammed from the panel, not from Alarm.com. This way, full functionality can be verified once programming is complete. It would be best to be sure the panel does not reboot again until the next firmware update, which will resolve this issue. Only PowerG devices are affected by this anomaly, any legacy RF devices using the 319.5MHz, 345MHz, or 433MHz frequencies, and any Z-Wave devices should not be affected by this issue.

If you haven't updated to 2.5.3 or 2.5.4 yet, it is recommended that you update locally at the panel, rather than through Alarm.com. You can find information on updating via Patch Tag or MicroSD card on our Qolsys IQ Panel 2 Plus Firmware Update Page. Sadly, this won't necessarily prevent this issue from happening, but by being onsite at the time of the update, you'll be able to verify proper PowerG sensor functionality on each of your sensors as soon as the update has completed. According to Qolsys, firmware version 2.5.5 will be released in the near future, though an exact date has not been provided. This version will resolve the root cause of this encryption key issue. Any additional future updates will also include the necessary fix.

If you're interested in no-contract, low-cost monitoring, or if you're an Alarm Grid customer (present or future) with questions, you can reach us at support@alarmgrid.com. We're here to check emails M - F from 9:00 am to 8:00 pm Eastern Time. Thanks for reading, stay safe!

We're checking out the best environmental sensors for our top security system picks for the 2020 holiday shopping season, which are the Honeywell Lyric, the Qolsys IQ Panel 2 Plus, and the 2GIG GC3e. Environmental sensors include life-safety sensors, flood sensors, and temperature sensors.

If you haven't seen our alarm panel 2020 holiday buying guide or our security sensor 2020 holiday buying guide, then be sure to go and check those out, as they will give a nice introduction to this buying guide for environmental sensors. You will need to make the same compatibility considerations for environmental sensors as you do for security sensors. The sensors you choose must be compatible with your system and communicate at a wireless frequency that is accepted by the alarm panel you are using.

As a refresher, here are the compatible sensor lineups for our recommended systems. Just like last time, the sensor lineups that are italicized and underlined represent the encrypted sensors that provide extra wireless security and protection.

• Honeywell Lyric - Honeywell SiX Series, Honeywell 5800 Series, 2GIG 345 MHz Series
• 2GIG GC3e - 2GIG eSeries Encrypted Sensors, 2GIG 345 MHz Series, Honeywell 5800 Series
• Qolsys IQ Panel 2 Plus 319.5 MHz - DSC PowerG Sensors, Qolsys S-Line Sensors, Qolsys Legacy 319.5 MHz Sensors, Legacy Interlogix Sensors, Legacy GE Sensors
• Qolsys IQ Panel 2 Plus 345 MHz - DSC PowerG Sensors, Honeywell 5800 Sensors, 2GIG 345 MHz Sensors
• Qolsys IQ Panel 2 Plus 433 MHz - DSC PowerG Sensors, Legacy DSC 433 MHZ Sensors

While security sensors look for signs of forced entry and unauthorized access, environmental sensors look for undesirable environmental conditions. Specifically, we offer environmental sensors that look for life-threatening conditions, such as a fire or the presence of carbon monoxide (CO) gas. We also offer environmental sensors for detecting floods, water leaks, and unusually high or low temperatures that indicate a broken HVAC system. We will cover each type of environmental sensor in greater detail later in this holiday buying guide.

Adding environmental sensors to your system offers a few advantages. For one, it makes your alarm system more versatile so that it is looking for more than just security breaches. You will also be able to check off more boxes on your certificate of alarm (CoA), and that could lead to bigger savings on your home owner's insurance. Make sure to check with your insurance company to see if that is the case.

Life-Safety Sensors

Life-safety sensors monitor for unsafe environmental conditions that could result in a loss of life. Specifically, this group is primarily comprised of smoke and heat detectors and carbon monoxide sensors. There are also special combination sensors and listening modules that we will discuss further down the line.

First, we will take a look at some of our most popular smoke and heat detectors. These sensors monitor for both the smoke and extremely high temperatures associated with a fire. It is recommended that you have at least one (1) of these sensors on each floor of your building, particularly inside of sleeping areas and in central and connecting areas such as living rooms and hallways.

When checking out these sensors, you might also look for one-go-all-go functionality. This means that when one detector on the network activates, all of the other compatible sensors on the network will also activate their sounders. This can be very important for ensuring that everyone is alerted to the emergency. Certain jurisdictions may require one-go-all-go as part of building codes, so check with your local fire marshal to see if that is the case.

Here are our top picks for smoke and heat detectors.

Sensor Name	Product Lineup	Compatibility	Range	Encryption	Notes
Honeywell SiXSMOKE	Honeywell SiX Series	Lyric	300 Nominal Feet	128-bit AES	Encrypted photoelectric smoke detector and 135°F fixed temperature and 15°F per minute rate-of-rise heat detector w/ 85 dB sounder. Supports One-Go-All-Go.

Now let's look at carbon monoxide sensors. These devices respond upon detecting unusually high levels of carbon monoxide (CO) gas. This gas is both odorless and tasteless, making it virtually impossible to detect without a proper sensor. The gas is extremely harmful to humans, and it can result in serious injury or death in a matter of minutes. We recommend installing at least one CO detector on each floor of your home or office. They are often installed outside of garages and furnace rooms where CO events are most likely to occur.

Here are our top picks for carbon monoxide sensors.

Sensor Name	Product Lineup	Compatibility	Range	Encryption	Notes
DSC PG9933	PowerG	All IQ Panel 2 Plus	2,000 Feet Open Air	128-bit AES	PowerG CO Detector w/ 85 dB sounder.

Qolsys IQ Carbon	Qolsys 319.5 MHz Series	319.5 MHz IQ Panel 2 Plus	300 Nominal Feet	None	Qolsys CO Detector w/ 85 dB sounder.

We also want to give some special recognition to some combination smoke and CO detectors from Honeywell. These sensors combine fire detection with carbon monoxide detection into one convenient life-safety device.

Here are our top picks for combination smoke and CO detectors.

Sensor Name	Product Lineup	Compatibility	Range	Encryption	Notes
Honeywell SiXCOMBO	Honeywell SiX Series	Lyric	300 Nominal Feet	128-bit AES	Encrypted photoelectric smoke detector and 135°F fixed temperature heat detector and CO detector w/ 85 dB sounder. Supports One-Go-All-Go.
Honeywell 5800COMBO	Honeywell 5800 Series	Lyric, GC3e, 345 MHz IQ2+	200 Nominal Feet	None	Encrypted photoelectric smoke detector and 135°F fixed temperature heat detector and CO detector w/ 85 dB sounder and freeze detection at 41°F.

Lastly, we want to mention a pair of listening modules. These devices actively listen for the Temporal 3 (T3) sound of an activated smoke detector or the Temporal 4 (T4) sound of an activated carbon monoxide sensor. These are commonly used with wired smoke detectors and CO detectors that would otherwise have no way of interfacing with an alarm system. If your smoke detectors or CO detectors are one-go-all-go, then, a single listening module can take over your entire wired detector network.

Here are our top picks for smoke & CO listening modules.

Sensor Name	Product Lineup	Compatibility	Range	Encryption	Notes
Encore FireFighter FF345	Encore 345 MHz Series	Lyric, GC3e, 345 MHz IQ2+	200 Nominal Feet	None	Offers both T3 Detection for Fire & T4 Detection for CO
Interlogix SLX-AD-T3	Legacy Interlogix 319.5 MHz	319.5 MHz IQ Panel 2 Plus	200 Nominal Feet	None	Only offers T3 Detection for Fire. Not for use with CO detectors.

Flood Sensors

Next, we'll be looking at flood sensors. These devices use probes to detect water caused by a flood or leak. It only takes a small amount of liquid to activate one of these sensors, so your system will be alerted before any serious damage occurs. Many of these sensors double as temperature sensors, so expect to see quite a bit of cross-over with that section as well. For best results, use your flood sensors in low-plane areas where leaks are likely to occur, such as underneath toilets, water heaters, and in basements. You might also see that some flood sensor have a reporting delay that is used for false alarm prevention. This will be listed in the notes section in the table when applicable.

Let's check out our top picks for flood sensors.

Sensor Name	Product Lineup	Compatibility	Range	Encryption	Notes
DSC PG9985	PowerG	All IQ Panel 2 Plus	2,000 Feet Open Air	128-bit AES	PowerG Flood Sensor w/ 6-Foot Detection Probe.

Temperature Sensors

The final type of environmental sensors we'll be checking out are temperature sensors. These sensors look for unusually high or low temperatures that indicate a broken HVAC system. When a temperature sensor is used for high-temperature detection, it should not be confused with a heat detector that looks for extreme temperatures only associated with fires. Instead, the high-end for a temperature sensor will usually activate at around 90°F. When a temperature sensor is used for low-temperature detection, it will sometimes be referred to as a freeze sensor. On the low-end, a freeze sensor will typically activate at a slightly higher than the temperature at which water freezes, which is 32°F. This is done to give the end user a bit of notice so that they can take action before the pipes freeze. You can typically expect a freeze sensor to activate between 40°F and 45°F. Most temperature sensors will offer both high and low temperature detection. And just like in the previous category, there is a lot of crossover with flood sensors, so you may see some repeats from the previous selection.

Here are our top picks for temperature sensors.

You have likely heard us talking about the benefits of PowerG Sensors at one point or another. Today, we figured we would break down the benefits of these sensors and explain why we like them so much. Let's take an in-depth look at PowerG Sensors and all of their wonderful benefits.

PowerG Sensors were originally designed for the hardwired DSC PowerSeries NEO Systems. By adding a compatible transceiver unit to your PowerSeries NEO, the system will be able to support PowerG Sensors. Johnson Controls, which you may know as the parent company of DSC, took the technology associated with PowerG Sensors, and brought it over to the Qolsys IQ Panel 2 System. This move was not a major surprise, as Johnson Controls also had partial ownership over Qolsys at the time, and Johnson Controls has since bought out Qolsys entirely.

The addition of PowerG support for the IQ2 marked the beginning of the Qolsys IQ Panel 2 Plus, which is how the system is still marketed and sold today. PowerG support is also available for the DSC Iotega, though that panel has largely flopped due to its lack of local end user programming. Today, the Qolsys IQ Panel 2 Plus represents the most popular panel for supporting PowerG. All versions and variants of the IQ Panel 2 Plus support PowerG Sensors, and their exceptional performance makes them the go-to choice for IQ2+ users who want equipment with the best versatility and protection.

Starting with the range, PowerG Sensors can be used from up to 2,000 feet away from the IQ Panel 2 Plus when they are used in an open air environment. By open air environment, we are talking about a perfect setting with a direct line of sight, and no obstacles between the sensor and the alarm panel. Most homes and businesses do not provide the ideal, "open air" environment, as there are usually walls and metal appliances present. When you see us mention that 2,000 feet open air range, take that with a grain of salt, because in practice, the range is likely a bit less. But still, we can undoubtedly say that PowerG offers arguably the best wireless range in the security industry. Even if its nominal range isn't quite as far as its "open air range", it is still a very powerful signal that can help you overcome the range issues that other sensor lineups may experience. It is great for use in detached garages, barns, multi-building complexes, and even just large industrial buildings.

To make matters even better, there is also a PowerG Repeater, the PG9920. This device will effectively double the range of any PowerG Sensor and help you overcome range limitations caused by thick walls and other obstacles or signal disruptions. The repeater works by taking the signal sent out from any PowerG Sensor and sending it out a second time with just as much power and force as when it was first sent from the original sensor. By strategically placing the repeater, it's theoretically possible to double the useful wireless range of these sensors. That would mean that they can be used from up to 4,000 feet away from the IQ2+ in an open air environment. And if your building is particularly large, you may even have repeaters going away from the IQ Panel 2 Plus System in different directions, including up and down in building stories above or below.

But PowerG Sensors offer more than just an impressive wireless range. They are also known for their exceptional security. This is thanks to their military grade 128-bit AES encryption. To put this as simply as possible, the PowerG Sensor and the panel share a unique encryption key at the time of pairing. The sensor must provide this encryption key to the panel whenever it transmits a signal. Additionally, the panel must then provide a return response with the encryption key as verification in order for the command to go through. In the past, we have referred to this two-way communication process as a "digital handshake". Because of this encrypted pairing process, a PowerG Sensor actively knows whether or not it is currently paired with a panel. You may need to factory default a PowerG Sensor before you can pair it with a new system.

PowerG Sensors also take proactive measures against RF jamming. When a wireless sensor communicates with an alarm panel, it does so at a certain wireless radio frequency (RF). When we talk about RF jamming, we are referring to any malicious technique that prevents wireless signals from reaching their intended destination. This is accomplished by blocking the receiver with a stronger signal at the same wireless frequency as the device that is legitimately trying to communicate with it. When this is done on an alarm system, the system doesn't receive the incoming signals from faulted sensors, and no action is taken during a security breach or an unfavorable environmental condition. Early wireless sensors did not take this into account, and this made RF jamming an effective way to defeat an older wireless system.

The way that PowerG Sensors overcome RF jamming techniques is through a process called Frequency Hopping Spread Spectrum (FHSS). This process involves splitting the RF bandwidth into multiple channels. Each independent channel represents a unique radio frequency for wireless communication to occur. The transmitter (the PowerG Sensor) and the receiver (the alarm panel) both agree on a set of channel hopping sequences that will take place. These sequences are encrypted and time-based for them to occur seamlessly. Since the transmitter and the receiver are both synchronized, they can switch between channels very rapidly. A potential intruder would never be able to re-tun an RF jamming device to keep up. In the case of the PowerG Sensors, the frequency hops occur between 912 MHz and 918 MHz. There are 50 different unique frequency channels that are used, and frequency switches occur 64 times per second. More information on FHSS is available here.

One other benefit of PowerG Sensors that we have never discussed previously is their Adaptive Transmission feature that helps them conserve battery life. This is why you will often see a PowerG Sensor with a very long expected battery life, sometimes more than ten (10) years). Adaptive Transmission involves two-way communication between the PowerG Sensor and the alarm panel. The alarm panel will tell the PowerG Sensor how well its signal is being received. The PowerG Sensor can then adapt its outgoing signal so that it reliably reaches the panel, without expending too much energy. The sensor and the panel regularly exchange this information so that the ideal amount of energy is always used in signal transmissions. This saves battery life in the long run.

We have also found that PowerG Sensors are extremely easy to enroll and they offer the reliable and effective performance that you should expect out of your security system. We wholeheartedly recommend them for use on the Qolsys IQ Panel 2 Plus, as well as any other compatible alarm system. It is expected that the upcoming Qolsys IQ Hub will also be able to utilize PowerG Sensors, so look forward to using PowerG Sensors on that panel once it is available.

For now, if you have any questions about PowerG Sensors or the systems that support them, or if you are interested in signing up for new alarm monitoring service, then please reach out to us by emailing support@alarmgrid.com. We'll be available to check your emails from 9am to 8pm ET M-F. We look forward to hearing from you!

Former "Malcom in the Middle" child star Frankie Muniz had a devastating experience last week. While visiting France to attend his uncle's funeral, Muniz's cat managed to turn on his sink. It flooded the house, destroying every wall, various pieces of artwork, personal photos and furniture.

The incident cost Muniz thousands upon thousands of dollars in damages to his five-story Phoenix house. He also lost priceless items that can never be replaced. It truly is a horrific event. We're sure that Muniz will overcome this challenge. He's a resilient man who currently serves as the host for "Dancing with the Stars: Juniors". He even recently got engaged. In the grand picture, this is just a small step back.

But we're also sure that this is a mistake he will never make again. Luckily, it's one that can be avoided fairly easily. Almost every security system can support flood sensors that can be used to let an end user know before serious water damage occurs. Once a small water leak is detected, the flood sensor will alert the alarm control panel. The user can then receive text and/or email alerts through an interactive service like Total Connect 2.0 or Alarm.com to let them know that their flood sensor has been triggered. Most flood sensors will activate with as little as a quarter-inch of water. This is well-before any serious water damage occurs.

Some users may wonder what to do if their flood sensor activates while they are away from home.The answer is fairly obvious. The user should determine the cause and stop the leak immediately if there is one. If you have a smart door lock, you can let a trusted friend or a neighbor into your home temporarily so that they can turn off the faucet or alert a plumber. You may also want to have security cameras in your home so that you can visually check for any flooding that may occur.

The thing to remember is that flood sensors are not very expensive. And many flood sensors will last as long as an alarm system itself. This one-time investment is much, much cheaper than the costs associated with a flooded home. Plus, many items are simply irreplaceable. If you value your home and your belongings, a few flood sensors is a small price to pay to protect what matters.
