C420 Programming Manual
1 GENERAL DESCRIPTION
1.1 INTRODUCTION
C420 is a modular conventional control panel which can handle from 4 (basic configuration) up to max 20 detection circuits (via
optional circuit modules) 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 an optional module, 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 an optional interface card, 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).
1.2 ALARMS AND TYPES OF ZONE
The control panel can switch into the following alarm conditions:
Alarm with siren output OFF
Alarm with siren output ON
Master alarm
Each alarm condition is characterized by the following configuration of outputs and user signalling (LED, buzzer):
STATE

The alarm condition of the control panel depends on the alarm condition of the zones and the presence of the master alarm
condition.
Each zone can be in one of the following alarm conditions, depending on its programming mode and the number of points in alarm
condition:
Alarm with siren output OFF
Alarm with siren output ON
