equipped with a 1.7 Amp power supply @ 28.5V DC nominal.
Power Supply and Charger
WARNING: In case of a short circuit or interruption of the analogue detection loop, only a
maximum of 32 detectors or call points (per loop) can be prevented, at any given time, of
transmitting a fire alarm. In order to assure compliance with this clause, loop isolators
have to be installed every 32 devices in the loop .
