Dsc WS4945 Wireless Door Window Contact 433 Mhz

Product Description

The DSC WS4945 is a 433 MHz wireless door and window contact designed for use in professionally installed security systems. It transmits an open or closed zone status signal to a compatible wireless receiver whenever a monitored door or window changes state. The WS4945 operates without hardwired zone connections, making it well suited for retrofit installations where running new wire is impractical. Security technicians and alarm system integrators install this device as part of a supervised wireless perimeter detection layout. The contact mounts to the door or window frame with the included magnet positioned on the moving sash.

The WS4945 is intended for residential and light commercial security applications where a 433 MHz DSC-compatible wireless receiver is already installed. It covers standard door and window openings and is appropriate for new construction as well as retrofit scenarios where access to wall cavities or conduit runs is limited. Installers typically deploy this contact on entry doors, casement windows, and sliding glass doors as part of a broader intrusion detection zone layout.

Installation Notes

Installation should be performed by a licensed alarm or low-voltage security technician in accordance with local codes and the authority having jurisdiction. Enroll the transmitter into the receiver or control panel before mounting to confirm communication. Mount the contact body to the fixed frame and the magnet to the moving door or window sash, keeping the gap within the manufacturer-specified range. Power down or place the panel in test mode before servicing any enrolled wireless zones to avoid triggering a live alarm signal.
