DSC WS4939 4-Button Wireless Key Fob with Multifunctional Clip

Take immediate control of your security and monitoring with the DSC WS4939 4-button wireless key fob. Designed for installers, facility managers and security teams, this DSC key fob provides fast, reliable remote access to your alarm and access control systems — arm, disarm or signal a panic alert from anywhere on site. The compact, water‑resistant housing and multifunction belt clip make it ideal for daily carry by staff or security officers, while the scratch‑resistant buttons stand up to heavy use.

Engineered for compatibility with DSC security systems, the WS4939 uses robust wireless connectivity and is powered by a long‑life lithium battery to minimize maintenance. A full 3‑second delay on the panic alarm helps reduce false activations without sacrificing rapid response, supporting more accurate monitoring and fewer dispatches. At just 2.2" high and weighing 0.5 oz, it fits comfortably on belts or key rings and replaces legacy RF5132WKK1‑433 models.

Upgrade your security toolkit with the WS4939 for dependable remote control, streamlined monitoring, and improved personnel safety. Order today or contact your DSC distributor to add these key fobs to your next installation.
