The DSC PG9939 Wireless 4-Button Key is a key fob and panic button that is used with PowerG-compatible alarm systems. The device has easy to identify buttons for disarming, arming away, arming stay and triggering a panic. Its included key ring makes it east for a user to carry on them.

To use the device, simply press and hold a button for one second. The one second activation requirement is used to prevent the device from activating accidentally. Additionally, the panic button must be held down for three seconds. This is to prevent any false alarms from occurring on the system. The alarm system should quickly receive the command and perform the desired action.

When a command is received by the system, the key fob device will produce an LED light and a beeping sound. This will provide the user with confirmation that a command has been successfully executed. The device's compact design and key ring will them let them conveniently carry the device anywhere they go.

The PG9939 is part of the PowerG Sensor lineup. These sensors work with any DSC PowerSeries Neo Panel and any Qolsys IQ Panel 2 System that has a PowerG daughtercard. As a PowerG Sensor, the PG9939 features an impressive 2 km communication range in open air, and it is protected against hacking attempts using 128-bit AES encryption.

NOTE: The maximum range for a PowerG Sensor when used with an IQ Panel 2 Plus System is only 2,000 feet in open air. This is considerably less than the advertised 2km range. The 2km range refers to when a PowerG Sensor is used with a DSC PowerSeries NEO System.

The DSC PG9939 is a 4-button key fob that interfaces with security systems that support PowerG technology. These systems include the Qolsys IQ Panel 2 Plus and any DSC PowerSeries NEO System with an added PowerG Transceiver. A user must press and hold one of the four (4) buttons for at least one (1) full second to send a command to the system. The system will then respond depending on how the key fob was programmed. Overall, the DSC PG9939 is a simple, yet effective device. It is great for anyone needing a key fob for a PowerG-compatible system. We give it a 5-Star rating.

There are many positive aspects regarding the DSC PG9939. For one, the sensor is small and compact. You will easily be able to fit it inside your pocket or purse for carrying around. There is even an attached key ring so you can secure it to your car keys. The four (4) buttons are easily identifiable, and they will help you use the sensor more easily. The key fob also has an LED light to provide visual indication of a command being sent. It can even produce a beeping sound for added verification of the device being triggered. We also like the fact that the PG9939 prevents false alarms by requiring that command inputs must be held down for a full second, and three (3) full seconds for a panic. Like all PowerG sensors, the device uses 128-bit AES encryption. It is supposedly the same range as any other PowerG Sensor (up to 2km in open air when used with the NEO), but you will likely find the range considerably smaller in practice. Still, you should find the PG9939 to offer a great wireless range for a key fob device.

There are not many downsides regarding the DSC PG9939. The design is somewhat dated, as it seems to resemble a much older key fob. We've seen many sleeker looking key fob models hit the market in recent years, so we're a bit surprised DSC didn't do more to make this sensor appear more modern. The fact that this key fob does not support dual-button inputs is also a bit of a letdown, as key fobs from other manufacturers regularly support this feature. As a wireless key fob, you will need to replace the batteries for the device every so often. But these downsides are relatively minor, and they do not stop us from giving the DSC PG9939 a 5-Star rating.

Good: Compact Design, Key Ring, Easily Identifiable Buttons, LED Light, Beeping Sound, False Alarm Prevention, Encryption, Great Wireless Range

Bad: Dated Design, No Dual-Button Inputs, Requires Battery Replacements
