FHF Ex-TWIN Explosionproof Secondary Ringer

Eaton’s FHF TWIN-EExll is a secondary telephone alarm and signal unit specifically designed for application in potentially explosive indoor or outdoor industrial areas.

This accessory is used to draw attention to incoming phones calls, the calls are indicated with high volume and signalled by the integrated strobe light. The TWIN-EExII offers two different operating modes that can be selected using the sliding switch, both signals are actuated by the AC ringing voltage.

With a compact design made from seawater-resistant cast aluminium coated with plastic the TWIN-ExII is durable in the harshest conditions which minimise damages and the need for maintenance.
