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

C420 Programming Manual 5
The control panel is in the state of
Alarm with siren output OFF when
oat least one zone is in alarm condition with siren output OFF
ono zone is in alarm condition with siren output ON
othe master alarm condition is not present
Alarm with siren output ON when
oat least one zone is in alarm condition with siren output ON
othe master alarm condition is not present
Master alarm when
othe user pushes the relevant key on the keyboard or a zone programmed to trigger the master alarm condition
goes to alarm with siren output ON.
The alarm condition of the zones and the control panel involves the activation of the zone relays and the supplementary siren
outputs (if present) as follows:
If the control panel is in master alarm condition, all the zone relays and all the supplementary siren outputs are activated
If the control panel is not in master alarm condition, the alarm condition of each zone is taken into account:
oif the zone is in alarm condition with siren output OFF, the zone relay is activated if it has been programmed to
be activated in this condition
oif the zone is in alarm condition with siren output ON, the zone relay and the supplementary siren outputs
associated to the zone are activated.
Each zone can be programmed in one of the following operating modes:
Single knock
When the zone is in idle condition and the circuit detects an alarm from one or more points, it switches
to alarm condition with siren output ON.
Single knock with
delay (*)
When the zone is in idle condition and the circuit detects an alarm from one or more points, it switches
to alarm condition with siren output OFF and an activation timer starts. When the timer expires, the zone
switches to alarm condition with siren output ON.
Double knock
When the zone is in idle condition and the circuit detects an alarm from one point, it switches to alarm
condition with siren output OFF. When the same circuit detects an alarm from another point, the zone
switches to alarm condition with siren output ON.
Double knock with
delay (*)
When the zone is in idle condition and the circuit detects an alarm from one point, it switches to alarm
condition with siren output OFF. When the same circuit detects an alarm from another point, an
activation timer starts. When the timer expires, the zone switches to alarm condition with siren output
ON.
Hotel (*)
When the zone is in idle condition and the circuit detects an alarm from one or more points, it switches
to alarm condition with siren output OFF and an activation timer starts. If the same circuit detects an
alarm from another point before the timer expires, the residual timer is compared with the hotel reload
timer. If the residual timer is higher than the hotel reload timer, the latter is loaded in the residual timer.
In any case, when the residual timer expires the zone switches to alarm condition with siren output ON.
(*) In the modes with delay, it is possible:
to increment, by pressing the INCREASE DELAY key, the siren output activation timer;
to clear immediately, by pressing the SKIP DELAY key, the siren output activation timer.
