WSM - Wireless Status Monitor, battery powered
Communicating via 900 MHz to an access control panel, the battery-powered Wireless Status Monitor reports in real-time any condition change caused by a contact closure or opening. While the WSM is most often used to monitor door position or to activate a local siren, the WSM can monitor other inputs from devices like glass breakage and temperature sensors.
Ultra-reliable communications result from several technological advances and incorporated features. 900 MHz Spread Spectrum technology enables high transmission power in a license-free band. Modulo 256 error detection maintain data integrity on each transmission and redundant transmissions ensure communication success. Periodic “heartbeat” signals assure good communications are maintained between the WSM and PIM. Lastly, Dynamic Channel Switching overcomes harsh RF environments by automatically changing channels to avoid potential interference.
Utilizing open standards for compatibility with virtually all access control systems, seamlessly integrate the WSM into new and existing installations. The WSM typically installs above the door and the two wires from a door position switch connect to it, significantly reducing installation time. Especially since up to 200 feet of cable can be eliminated from the WSM to the access control panel.
Security is also maintained as the WSM utilizes Spread Spectrum transmissions, which are encoded with 128-bit keys, to yield a system that is virtually uncompromisable. In addition, scalability is virtually unlimited as each Wireless Status Monitor has nearly a million addresses to choose from during the linking process.
