Hybrid Fire Alarm Control Panel works on four wire communication protocol such that in case of detection of an event in any zone then the ZMU of that respective zone will communicate to the main panel about the occurrence of the event in that particular zone. The Panel can be availed up to 128 fully monitored zones with up to 2560 conventional detectors and microcontroller based fire alarm panel. The Panel has 16 zone monitoring units with up to 8 zones per ZMU and 16 relay modules with 8 zones relay output per relay module. The Panel has short circuit/ overload protection, "fire", "fault" relay output per zone monitoring unit, per relay module and is fully programmable via integral alphanumeric keypad. The Panel has 256 events storage capacity, password protection and repeater connectivity. The Panel has mains voltage from 220 to 230v ac, frequency from 50 to 60 Hz, operating voltage of 24V DC, quiescent current of 1 ma, current consumption for external devices of 4A maximum. The Panel has CRC sheet made housing, white colour and has weight of approx 17000 gram. The Hybrid Fire Alarm Control Panel has LCD and LED indication, operational temperature range of -10/ +60 ° C, relative humidity resistance of 93 ±3 % at 40 ° ?.
