Description
PAVA EST-DFMS is a Fireman Microphone. A EST ENT VES fireman microphone is a monitored external device working with Control Units in a redundant communication ring. It can thereby perform a superior function of a system control unit, too.
A fireman microphone can be used to activate alarm messages as well as general public announcements, to choose individual zones and to broadcast live voice messages. The PAVA EST-DFMS is equipped with programmable function keys which can be used to assign functions as required. Up to 5 EST-EKB-20M keyboard extensions with additional function keys can be attached to a fireman microphone.
A CPU switch enables immediate and direct broadcasting of announcements to all zones without any involvement of the control system even during a failure of the central processor. The microphone is able to automatically detect a key failure and an audio path from the microphone capsule (inclusive) to the Control Unit.
A fireman microphone is also equipped with an intercom function and is able to communicate with other microphones in the system.
- Black-box function – recording all announcements played during an alarm
- Built-in SFP modules and CAT5e for simplicity of implementation of the loop topology
- RS485 for communication with external systems
- Intercom function between all fireman and zone microphones
