All operations are performed using the control panel keypad. Pressing a key is acknowledged by a short buzzer tone. The keys can be locked with a key switch for unauthorized operation.
Detector zones (1-8) and technical zones (9-13) can be switched on/off using function keys and the keypad. Deactivated zones will not trigger alarms.
Relay outputs (1-13) can be switched on/off via function keys and the keypad. Deactivated outputs will not notify alarms.
Automatic zones 1-8 can be switched to Test mode. The zone status is indicated by a yellow/red flashing LED.
Revision mode has priority over test mode. When activated, outputs programmed with the status function 'Revision' remain activated.
The panel can be reset using a function key. This restarts the system and resets internal panel status and visual displays.
The lamp test activates all visual displays and the control panel buzzer until the key is released.
