The ALPHA 2 unit is a fire detection panel. It has been developed and engineered according to European
standards: EN 54-2 and EN 54-4.
It has 2 resistive monitored conventional lines which are physically separated. The panel can receive at
maximum 64 detectors and/or manual call points in total.
Each zone has visualization indicators which give immediate signalization of alarm, fault and
enabling/disabling. All signalisations of the panel are available through leds and piezoelectric buzzer.
Control functions are available on a membrane keyboard.
ALPHA 2 is recommended for small conventional installations with 64 points maximum.
