C402
Fire detection control units C402 and C404 control up to two and four independent zones, respectively, with 32 devices per zone as a maximum. Each line is considered as a zone and can be either activated or deactivated via a command from keypad. The control unit has two outputs: one general alarm siren output activated with at least one zone in alarm condition and one general malfunction siren output activated when a malfunction condition occurs either on the control unit or in a zone. General alarm siren output can be either activated or deactivated via keypad. Other outputs (relay, general alarm and zone alarm) are available on optional relay board. It is possible, for each single zone independently, to decide whether the alarm notification is to be sent with one alarmed device only (single consensus) or with at least two alarmed devices (double consensus). This helps prevent false alarms.
