Emergency Warning Systems
Emergency Telephone System
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. It is intended for facilities in which the emergency services radio communication system is likely to experience difficulties, or as otherwise 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.
The ETS Master Controller has a built-in backup battery. It will continue to function if all other telephones or electrical systems fail. The battery and system wiring are supervised for faults.
Short-circuit isolators are built in to every jack-point, and to the loop terminals on the master controller. A single wiring fault (open or short circuit) will not affect the operation of any handset in the system.
Advantages of the Pertronic system include excellent audio quality, battery condition monitoring, fault tolerance due to the presence of a short-circuit isolator in each jack-point, and automatic recovery from fault isolation.
