WSM517 Wireless Support Module

The Alpha Communications® WSM517 Wireless Support Module is for use with the AlphaEcall™ 200 (AEC200) Series Wireless Emergency Call System. When the WSM517 is connected to the SF117/2A or SF119/2A Emergency Station, the WSM517 operates as a wireless device in the AlphaEcall™ 200 (AEC200) system. When properly installed, the WSM517 / SF117/2A assembly may be located in a bedroom, bathroom or other area that will not be exposed to water (stainless steel and other metal fixtures may interfere with signal transmission).

The WSM517 is based on EchoStream® spread spectrum technology and transmits signals at the 900 MHz frequency. It includes a universal transmitter with two (2) screw terminal connectors for connection to the SF117/2A (or SF119/2A) Emergency Station. The WSM517 requires no other wiring connections and is powered by a user-replaceable 3V lithium battery.

For surface mount applications, the WSM517 and SF117/2A (or SF119/2A) assembly can be mounted inside the optional model IHS527 surface plastic housing.
