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.

Hi DIYers! We have a simple, yet effective tip for you today. The tip is to keep a second key fob device by your bed for easy access. This can be a great way to trigger a panic and scare off an intruder if you hear a break-in. You can also use this key fob as a backup for your main one.

Being woken up in the middle of the night due to a break-in can be a very scary feeling. Most users will arm their systems to stay mode at night so that an alarm will occur if someone tries to break-in. But maybe you forgot to arm your system, or maybe you want to activate a siren to try and scare off the intruder. In that case, having a key fob next to your bed can be very helpful.

Most key fobs have a designated panic button that you can use to activate an immediate intrusion alarm. By pressing and holding this button, you are telling your system that you are in danger and that help is needed immediately. It's a great resource to have in these rare, but extremely scary, situations. Just be aware that some panels may require you to specially enroll the panic zone. Additionally, some key fobs may require dual-button presses to activate panics.

Once you activate the panic button, your system will immediately go into alarm. This can involve triggering a siren to scare off any intruders. Alternatively, you could set up a silent alarm so that the police show up without the intruder knowing. However, a loud, audible alarm will be much more effective in scaring away an intruder. You might even set up on input for an audible alarm and another for a silent alarm. It's up to you.

But keeping a key fob next to your bed is more for than just having an option for triggering a panic in the middle of the night. It's also good to have a second key fob as a backup option in case you lose or misplace your first one. You can always grab the other key fob by your bed if you need to quickly grab a fob. You can also use it to set your system to arm stay from your bed if you forgot to do so while you were by your panel or keypad earlier.

Remember, a key fob isn't the only way to access your system remotely. You can always access your system from your Android or iOS device through Total Connect 2.0 or Alarm.com. Both of these platforms offer mobile apps allow you to arm and disarm your system from anywhere. Just keep in mind that you will need a monitoring plan to use TC2 or ADC. And of course, you can always dial 911 if you believe you are in a dangerous situation. But a key fob panic can still be useful in certain situations.

And if you just want a simple device for triggering panic alarms without having arming and disarming functions, we offer standalone panic buttons as well. These are convenient devices that you can activate if you hear something suspicious to trigger an immediate system alarm. You might also consider getting outdoor sirens that you can activate to try and scare away anyone lurking outside your home. And remember that if you have monitoring service, you can set up how your system responds during alarm events. This includes what action(s) the central station will take and when you receive text, email, and/or push notifications regarding any triggered panics.

If you do decide to get additional key fob devices or a panic button for your system, you will need to make sure they are compatible. Our team can help you with that. Remember that we offer free support for all our monitored customers. We can help you determine the perfect key fob option for your needs so that you can your family can feel safe at home. The best way to contact us is to email support@alarmgrid.com. We will check your email at our earliest convenience and reply back as soon as possible. We look forward to hearing from you!
