DSC PG9939 PowerG Compact Four-Button Security Key

The DSC PG9939 is a compact four-button PowerG key for users who want portable system control without carrying a larger keypad. The buttons can be programmed for common actions such as stay arming, away arming, disarming, and panic, subject to the connected panel and the security plan Allied establishes for the property.

Both light and sound confirm that the panel completed a requested command. To reduce false alarms, the panic function uses a full three-second activation delay, while the other buttons incorporate a one-second delay that still keeps routine arming and disarming responsive.

The 2.4-inch body is shorter and wider than the slim PG9929, and the manufacturer rates its CR2032 battery for up to eight years of typical use. As part of an Allied home security system, the fob offers simple everyday control while PowerG frequency hopping, adaptive transmission power, and AES-128 encryption handle the wireless link behind the scenes.
