The DSC PG9945 Wireless Door and Window Contact that is capable of monitoring virtually any door or window. It is a surface mount sensor that is easy to install, and it operates using an included magnet. The sensor is part of the DSC PowerG Series, giving it great range and reliability.
The device operates much like that of any other door or window contact. It includes a magnet for its operation. The sensor is installed on the door or window frame, and the magnet is installed on the door or window itself. For best results, the magnet should be placed within 0.25 inches of the sensor. When the door or window is opened, the magnet will separate from the sensor. This will cause a reed switch inside the PG9945 to activate. The sensor will then send an alert to the alarm system to let it know that the door or window has been opened. The system will perform the programmed action for that zone.
Another feature of the DSC PG9945 is its auxiliary input. This allows it to serve as a wireless transmitter for a single hardwired device. The device will connect directly with the input on the PG9945, and the PG9945 will send a wireless signal to the panel on its behalf. The input will support Normally
Open, Normally Closed and Single End-of-Line devices. That gives the user a large number of options in choosing a hardwired device to use with the PG9945.
As a PowerG Sensor, the PG9945 offers a particularly powerful signal range. In open air, the sensor will work reliably from up to 2 kilometers away from the panel. This means that it could be used across the entire property, such as in a detached garage or a barn. The sensor also utilizes 128-bit AES encryption. This means that any time the sensor sends a command to the system, the panel will need to send a compatible return signal to the sensor for the command to go through. This prevents the sensor from being hacked or taken over wirelessly by others. The panels that will support the encrypted signal of the PG9945 include the DSC PowerSeries Neo Panels and any Qolsys IQ Panel 2 with a PowerG daughtercard.
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.
