Conventional Automatic Fire Detection and Alarm Central Expandable Up to 128 Zones / Relays – CDL Cofem

Description

Conventional Automatic Fire Detection and Alarm Central Expandable Up to 128 Zones / Relays – CDL Cofem

Conventional fire detection center London.

The central London has been designed according to EN Standard 54 part 2 Y 4 according to the latest directives, successfully passing the most severe tests of environmental conditions, conducted electrical noises, magnetic disturbances, vibrations, etc.

Based on microprocessed technology of 16 bits, uses this capacity to manage the detection system and perform associated maneuvers. Supports most conventional detectors on the market, operating with the following voltage levels:

- Open line 22,5 V 24 V
- State of Surveillance 19 V 22,5 V
- Detector alarm 7 V 16 V
- Push Button Alarm 3,5 V 7 V
- Cross Line 0 V 3,5 V

Measuring the value of the line voltage and knowing the voltage margins mentioned above, a correspondence can be established with the indication of the central.
