System fault:
There are 2 different failure states, which are indicated by the failure LED flashing or
being continuously lit:
− A flashing system fault LED indicates a communication fault, i.e. at least one of the
data buses is interrupted or disturbed. In this case, the plug connections on the MMDS
D08-L and the MMDS-SD serial distribution box must be checked for correct seating.
− A continuously lit system failure LED indicates an internal fault. The unit is faulty if this
status persists after it is switched off and on again.
Operation:
At the front are three buttons with which various functions such as Alarm-Quit are poss-
ible. The buttons have the following functions:
Standard function: Acoustic quit or switch-off of the internal horn.
All other monitoring devices in the system are quitted too.
Test function: Holding the key for at least 5 seconds activates the built-in buzzer.
Standard function: Visual quit, i.e. all flashing alarms stop flashing but remain lit
provided that an acoustic quit was previously activated. All other monitoring devi-
ces in the system are quitted too.
Test function: Lamp test, i.e. all LEDs are activated for as long as the button is
pressed.
Standard function: If the reason for the alarm has been eliminated and a quit has
been activated the reducing or stop alarm can be reset in the central unit using
this button.
