3.5 Loss of mains power (Power failure)
Important!
Any work on the communication interface, such as the replacement of the batteries, switching
on the interface on the circuit board and changing the fuses may only be carried out by
authorised persons
(see Maintenance and Repair Instructions) .
In case of a power failure, the function of the communication interface will be maintained for 12
hours by a battery. The detection and the fire extinguishing functions will not be affected by the
power failure, as this part of the extinguisher system works purely mechanically or pneumatically.
The communication interface indicates the current state as follows:
Operation (green)
Batter operation (yellow)
Flashing light every 60 min. for 8 sec.
Acoustic signal every 60 min. for 8 sec.
