Emergency Paging (EM PA) is highest priority paging within the MPA 1600 system.
• EM PA overrides any audible entertainment channels within the system while active
• EM PA overrides any external entertainment systems by means of an entertainment signal
while active (see documents 03118-100-BD and 03118-100-EC)
• EM PA overrides any volume controls (entertainment) while active
• EM PA overrides normal paging (PA)
• EM PA overrides General Alarm (GA) and other audible alarms while active
• EM PA overrides external GA systems by means of an external GA mute signal while
active (see documents 03118-100-BD and 03118-100-EC)
• EM PA messages are always broadcasted to all zones/areas in the system.
Emergency paging is initiated from the Control unit MPA 1601, 1605, 1606, or 1643 by means of the
EMERGENCY PA (EM PA) button. This button is marked by red colour.
