Telephone Kit ETS

Product Overview
The Pertronic Emergency Telephone System (ETS) is a self-contained, fully protected telephone system for the exclusive use of fire-fighters. The system provides party-call communication between fire-fighters and is intended for facilities where emergency services radio communication may be problematic or as specified by the local fire authority.

The ETS consists of an ETS Master Controller, up to 100 ETS Isolating Jack-Points located throughout the facility, and a set of up to ten portable ETS Handsets. A purpose-built lockable cabinet with shelf space for up to ten Pertronic ETS Handsets is also available.

The ETS Master Controller includes a built-in backup battery and supervised wiring so the system will continue to function if other telephones or electrical systems fail. Short-circuit isolators are built into every jack-point and the master controller loop terminals to ensure a single wiring fault (open or short) will not affect the operation of other handsets.
