Summary of Main PCB Connections
Battery / Ground Terminals
GND Equipment Ground Terminal - connection must be intact at all times.
BATT- Battery Negative - Connect to the -ve (black) terminal of the battery.
BATT+ Battery Positive - Connect to the +ve (red) terminal of the battery.
Output Triggers (Terminal PLA)
1. Fire trigger
2. Panic trigger
3. Alarm (Intruder) trigger
4. Tamper trigger - responds to tamper alarms when the system is unset.
When full set, a tamper alarm activates the Alarm output trigger.
5. Fault trigger - responds to low battery, mains fail, memory checksum
failure and watchdog reset.
6. Programme trigger - activates when programming mode is entered.
Power / Keypad Terminals (Terminal PLB)
AC These two terminals connect to the 13 V a.c. output of the mains
transformer. They are not for direct connection to the mains supply.
Data Out Connects to the Data Out (yellow) terminal of each fixed LCD
keypad on the system.
Data In Connects to the Data In (green) terminal of each fixed LCD keypad.
12 AUX Auxiliary 12 V supply - two pairs of terminals are available for
connection of remote keypads and auxiliary fused devices.
Bell / Zone / SW- terminals
1. Switched Negative Supply - This output can be programmed as:
(a) Negative supply for smoke detectors or other latching devices
which require the interruption of the supply to reset. The output is
normally 0 V switching to +12 V for 6 seconds on the second entry
of Code + Off after an alarm condition. The output can also be
activated at any point in the unset state by pressing the
Ö
and 1 keys
together.
(b) Printer data output for a serial printer.
(c) Sounder output.
2. Strobe negative - for connection with external strobe negative.
3. Positive bell / strobe supply - common positive, limited by fuse to 1
Amp maximum (labelled F3 in Figure 2.1 PCB Connections).
4. External bell negative - for connection with switched negative trigger
on external bell or SAB switched negative trigger.
5 - 36 Alarm zones 1-8, wired as standard double poll zones. Normally
open devices may be connected between alarm and tamper loops.
Zones programmed as Not Used must have the both alarm and tamper
loops linked out.
