DSC WS4945

The DSC WS4945 is a wireless door and window contact sensor operating at 433 MHz, designed for integration with DSC wireless receivers to provide intrusion detection on entry points throughout a facility. It features a pre-installed lithium battery with a convenient activation pull tab, a built-in reed switch with normally closed contact configuration, and external contact input capability for hardwired door integration where magnet placement is constrained.

Key Features

• Compact wireless door/window contact transmitter for entry point monitoring
• 433 MHz frequency with compatibility across all current DSC wireless receivers
