Wall-mounted emergency microphone

The wall-mounted emergency microphone allows general calls with priority over all other inputs (including pre-recorded messages during ALERT and EVAC events). It features self-diagnosis and system status reporting functionalities, in compliance with EN 54-16: 2008. Up to four microphone bases can be daisy-chained on the line; the first is powered directly by the central unit, while the others require external 24V@500 mA power supplies. The microphone panel is equipped only with the protected bistable emergency button (with red light), which is used for alert and evacuation announcements with active alarms (general call function only). The status of the microphone is indicated by the luminous LED bar. Dimensions (W x H x D): 115 x 210 x 36 mm
