'Zone': Reset behavior of the manual call points
● The reset behavior of an activated manual call point can be selected:
– 'ALARM' can always be reset; 'Glass broken' is indicated.
or
– 'ALARM' cannot be reset.
● ↑ Blocking of the isolation
– If the isolation blocking function has been configured, the 'Zone' cannot be
switched off.
● 'Detector test' timeout
– After the expiry of a configurable delay the system automatically cancels
the 'Detector test' state. This function can be deactivated.
● Switching devices back on
– When devices are switched back on, they are in an undefined state for a
short period. The ↑ 'Station' changes to the 'Not ready' state for this
timespan.
● Simulation function
– With the simulation function the 'Zone' switches from the normal operation
mode to 'Pre-ALARM' and then to 'ALARM'. The controls are activated as if
the detectors had triggered an 'ALARM'. Reset is performed by means of
the keys on the ↑ PMI.
The ↑ Control tree represents the control in the fire detection system. ↑ control
groups are grouping units for configuration and operation.
Control groups in ↑ 'Control tree'
● 'Alarming control group'
● ↑ 'Fire control group'
● 'Evac control group'

(Cause) and an output (Effect).
● Elements of the 'Alarming control group' are controls for internal and external
↑ alarm devices
– Remote transmission outputs for 'Fire' and 'Fault'
