Dsc PG9945BR Wireless Door Window Contact 915 Mhz

Product Description

The DSC PG9945BR is a 915 MHz wireless door and window contact designed for use with PowerG-compatible security systems. It monitors the open and closed status of doors, windows, and other entry points, transmitting encrypted wireless signals to a compatible receiver or panel. Installers use this sensor as part of a broader intrusion detection layout where running wired contacts is impractical or cost-prohibitive. The 915 MHz frequency provides reliable RF penetration through walls and floors, making it well suited for both new installations and retrofits in occupied structures.

This contact is intended for residential and light commercial security applications. It installs on door frames, window sashes, and similar entry points where two-part reed-switch sensors are appropriate. Security technicians and alarm installers are the primary trade for this device. The unit ships as a single sensor, making it easy to order exact quantities for a given job without excess inventory.

Key Features

Installation Notes

Installation should be performed by a licensed alarm technician familiar with low-voltage security systems and applicable local codes. Before installation, power down or disarm the security panel as required by the manufacturer procedure. Mount the sensor body on the fixed frame and the magnet on the moving door or window sash, keeping the two components properly aligned within the specified gap tolerance noted in the product manual. Avoid mounting near large metal surfaces or sources of strong RF interference that could degrade wireless communication.
