SF527ES Wireless Support Module for SF337C (TC500 Series)

  • Reliable 900MHz frequency operation
  • 3V Lithium battery included
SF527ES Wireless Support Module

The Alpha Communications® / TekTone SF527ES Wireless Support Module is for use with the Tek-CARE®500 (TC500) Wireless Emergency Call System. When the SF527ES is connected to a SF337C Waterproof Emergency Station, the SF337C operates as a wireless device in the Tek-CARE®500 system. When properly installed, the SF527ES/SF337C assembly may be located in a shower, bath or tub room, regardless of environmental conditions (stainless steel and other metal fixtures may interfere with signal transmission).

The SF527ES is based on EchoStream® spread spectrum technology and transmits signals at the 900 MHz frequency. It includes a universal transmitter and a pre-assembled 7-pin wiring harness for connection to the SF337C Emergency Station. The SF527ES requires no other wiring connections and is powered by a user-replaceable 3V lithium battery.

For surface mount applications, the SF337C and SF527ES assembly can be mounted inside the optional model IHS527 surface plastic housing.
