The FuFi-wire-ISM-4 is a radio transmitter in a flat IP65 drawer housing (dimensions 52 x 33 x 9 mm).

It is used for the radio-technical connection of any devices or components with potential-free NC or NO contact (e.g. step mats) to CLAS. To connect the external contact, 2 connection wires are led out of the housing. An external status LED can be connected via two further connection wires.

Current alarm states or an activated parameterisation are signalled by a two-colour LED.
Optionally, by briefly placing a CLAS nurse smartphone on the transmitter, its transmitter ID can be read out.

Individual adaptation to the desired application is possible via a flexible radio-based parameterisation option.

Depending on the selected parameterisation, the transmitter operates for several years with a button cell battery. Thanks to its drawer housing, which can be opened without tools, the battery can be changed within a few seconds.

In care facilities, the alarm is sent via SR-ISM-WLAN radio gateways to the CLAS alarm server.
