1 Presentation of the external power source

The external power source ZAFIR of COFEM represents all the experience learned in the
design and manufacture of fire-fighting equipment during its more than 40 years of market
presence.
This power supply includes different models to suit precisely the needs of each installation,
offering two models of different sources: ZAFIRPWS2 (capacity 1.5 amps at 30V output) and
ZAFIR PWS5 (4 amps).
Technical characteristics:

External power supple to power fire-fighting equipment at 20-30,5Vdc.

Power capacity: 1,5 amps for model ZAFIRWS2 and 4 amps for ZAFIRPWS5 model.

1 output of fault from dry contact C/NO/NC (Common/ Normally Open/ Normally Closed).
This output allows integration with other systems.

1 auxiliary output of 20 ~ 30,5Vdc supervised and protected by a fuse for external power
supply of fire doors electromagnets, sounders, relay modules, etc.

1 output battery with the ability to load and supervise two 12V 7Ah batteries connected in
serial.

