C420 Installation Manual
1 GENERAL DESCRIPTION
1.1 MAIN CHARACTERISTICS
C420 is a modular conventional control panel which can handle from 4 (basic configuration) up to max 20 detection circuits (via
optional circuit modules ML420) where it is possible to connect up to 512 points.
Each circuit covers a zone which can house up to 32 conventional points (the control panel, though, has to be compliant with the
constraint of max 512 total points in the field).
Each zone is permanently associated to a dedicated relay which is activated when the zone goes to alarm condition.
Moreover, the control panel is equipped with the following outputs and relays:
•
one cumulative alarm relay output
•
one cumulative siren relay output
•
one cumulative fault relay output
•
one programmable relay output activated as a consequence of lack of AC mains or presence of at least one exclusion
•
one supervised siren output
•
four supplementary supervised siren outputs, available on the optional module MR420, which can be associated
independently of each other to one or more zones.
The control panel is equipped with an alphanumeric 4X40 display and a 12 keys keyboard. Moreover, an external PS2 keyboard
can be connected to the control panel in order to ease the input during the programming phase.
By using the optional interface board RS232/485, the control panel can be connected to a remote LCD annunciator which shows
the contents of the display during the monitoring phase and a printer with Centronics interface for event log printing.
The control panel is equipped with an event log able to store up to 1000 events.
Also, there is a clock with battery backup for keeping date and time updated even when the control panel is powered off.
The control panel can house internally two 12V-12Ah (RB1212 type) batteries (sold separately).
