Indicator module

The indicator module is optional and is possibly not equipped yet. The operation

thus differs largely and is mentioned in this manual in the corresponding sections.

Key switch

The key switch is optional and is possibly not equipped yet. It serves for enabling

operation and has the same function as the password (see section 'Enabling oper-

ating level 2').

4.2 Function

4.2.1 The most important functions

Function levels

The fire detection control unit is secured against unauthorized manipulation by the

following operating levels:

 Operating level 1: operation always possible

 Operating level 2: control panel only possible with password or key switch

 Operating level 3: operation only possible for the service technician

On operating level 1, only the most important commands in case of alarm can be

issued. All other commands are only accessible on operating level 2.

Power supply

The fire detection control unit is always connected to the power supply system. In

case of a mains failure the control unit is fed from the built-in batteries. Battery op-

eration in case of mains failure is limited.

4.2.2 Detector zones

In the fire detection system, several detectors are always combined in a so-called

detector zone. Depending on the version, the control unit monitors 2, 4, 8, 12 or 24

detector zones.

Up to 32 detectors can be connected to one detector zone. In case of fire, only the

detector zone of the alarming detector is indicated on the control unit. It is thus im-

portant to know where the detectors of the individual detector zones are located.

The service technician has handed over a building plan to you, in which the alloca-

tion of the detectors to the detector zones is indicated.
