8.4 MPA 1603 Alarm Panel
8.4.1 Alarm setting
The MPA 1600 can handle 4 different alarm types. The General Alarm is mandatory, the others
are optional and thus of lower priority and significance.
The alarms can be activated from the MPA 1603 alarm panel. All alarms will temporarily
override any PA activity from any users. Users can regain access by reactivating EM-PA/PA.
Alarm priority:
1. General alarm (All zones)
2. Alarm 2 (configurable / optional)
3. Alarm 3 (configurable / optional)
4. Alarm 4 (configurable / optional)
Check that pressing the “Alarm 1” General Alarm key on the
MPA 1603 alarm panel will cause a “Muster alarm” alarm tone
in all areas regardless of any zone previous selection.
"All" zones are selected automatically. Pass/Fail
