Terminal no. Description
1
Output for detector / system power
supply protected by 1A PTC.
2 GND
3
TC output for resetting local detec-
tor memories.
4
Zone A1 detector input: a terminal
with a series of normally closed
contacts. The other terminal must
be connected to GND.
5
Zone A2 detector input: a terminal
with a series of normally closed
contacts. The other terminal must
be connected to GND.
6
Zone A3 detector input: a terminal
with a series of normally closed
contacts. The other terminal must
be connected to GND.
7 GND
8
Zone B1 detector input: a terminal
with a series of normally closed
contacts. The other terminal must
be connected to GND.
9
Zone B2 detector input: a terminal
with a series of normally closed
contacts. The other terminal must
be connected to GND.
10 GND
11
Zone C1 detector input: a terminal
with a series of normally closed
contacts. The other terminal must
be connected to GND.
12
Zone C2 detector input: a terminal
with a series of normally closed
contacts. The other terminal must
be connected to GND. This input can
be transformed into a 24h-type one
for the connection of technical alarm
detectors by using jumper JP1.
13 GND
Terminal no. Description
14
24h line input (tamper): a terminal
with a series of normally closed con-
tacts. The other terminal must be
connected to GND.
15
Output for technical alarms with C2
zone input (e.g. for connection to the
telephone dialler): open collector
13.8V / 100mA max., closes
towards the negative for alarm
(enabled with Jp1 not inserted).
16
Pre-alarm output: open collector
13.8V / 100mA closes towards the
negative for warning signals during
entrance/exit.
17
Auxiliary siren control output: contact
13.8V/1A max, connected to V+, clo-
ses for alarm; protection from overlo-
ads by 1A PTC.
18 GND
19
Outdoor self-powered siren battery
recharging
20
Self-powered siren control output
(+denied): contact 13.8V/1A max,
normally connected to V+ (13.8V);
protection from overloads by 1A PTC
21 GND
22
Auxiliary alarm output (e.g. for con-
nection to the telephone dialler): open
collector, closes towards the negative
for alarm 13.8V / 100mA max.
23
"Low battery" output: open collector
13.8V/100mA max., closes towards
the negative when battery voltage is
less than 10.5÷11V.
24-25-26
Serial line for connection to the remo-
te activation point (terminals: 24
negative power, 25 serial signal and
26 positive power).
