C404 CONTROL UNITS
Control unit with micro processor for 2/4 zones
Fire detection control units C402 and C404 control up to two and four independent zones,
respectively, with a maximum of 32 devices per zone. 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 sounder output activated with at least one zone
in alarm status, and one general malfunction output activated when a malfunction condition occurs
either on control unit or in a zone.
General alarm sounder output can be either activated or deactivated via keypad. Other relay, general
alarm and zone alarm outputs are available on optional relay board.
It is possible, for each single zone independently, to decide whether alarm notification is to be
obtained with one alarmed device only (single consensus) or with at least two alarmed devices
(double consensus). This allows to avoid false alarms
