Door latch contact
The door latch contact is used for blocking the activation of extinguishing in case of
maintenance work. This blocking option is used as a rule in unattended
extinguishing areas. As soon as the door to the extinguishing area is unlocked, the
automatic activation of extinguishing is blocked; the manual activation, however,
remains active.
The extinguishing control unit has an extensive self-monitoring functionality. If the
control unit detects an error such as, for example, loss of extinguishing agent, then
it will be indicated as a fault. Faults are normally transmitted to a receiving station.
Faults should always be eliminated as soon as possible.
The extinguishing system must be serviced on a regular basis. Only in this way is it
possible for the system to function perfectly even in a serious event. Therefore,
carry out the following maintenance work on a regular basis:
Check the control unit
Check the detectors
Check the alarm horn and the illuminated warning panel
Check the remote transmission or forwarding to the fire detection system
Check the fire control (ventilation control, door closer)
Check the blocking devices (Emergency hold or abort button)
Check the status of extinguishing agent storage
