Motherboard layout:
AC +……………..AC input maximum 16.5V 40va
AC -………………Negative to be taken from any negative
(Earth) ................ This must be connected to building earth were possible, alternately to mains earth
AUX 12V ............ 12V + to peripherals i.e. IR detectors, beams, etc. (Fused at 1 amp)
AUX NEG……….Negative to be taken from any negative or common.
Siren - ................ Negative to siren (Fused at 3 amps) and supervised. See note below
Siren + ............... Positive to siren
Panic + ............... Panic input EOL resistor 2K7
Panic - ............... Panic input EOL resistor 2K7
KEYPAD R + ...... Keypad + (Red)
KEYPAD Y ......... Keypad data (Yellow)
KEYPAD G ........ Keypad data (Green)
KEYPAD B - ....... Keypad – (Black)
Tamper .............. Tamper input NO to Negative
NEG ................... Negative 12v output
TRIG O/P 4 ........ Trigger output 4
TRIG O/P 3 ........ Trigger output 3
TRIG O/P 2 ....... Trigger output 2
TRIG O/P 1 ....... Trigger output 1
ZONE 1 .............. Zone 1 input EOL resistor 2K7
C ........................ Common
ZONE 2 .............. Zone 2 input EOL resistor 2K7
ZONE 3 .............. Zone 3 input EOL resistor 2K7
C ....................... Common
ZONE 4 ............. Zone 4 input EOL resistor 2K7
ZONE 5 ............. Zone 5 input EOL resistor 2K7
C ....................... Common
ZONE 6 ............. Zone 6 input EOL resistor 2K7
ZONE 7 ............. Zone 7 input EOL resistor 2K7
C ....................... Common
ZONE 8 ............. Zone 8 input EOL resistor 2K7
Buss R…………...Peripheral bus positive
Buss B…………...Peripheral bus negative
Buss G…………...Peripheral bus data (green)
Buss Y…………...Peripheral bus data (yellow)
Note: The siren output is supervised against an open loop. If no siren is to be used a 2K7 ohm resistor must
be used to strap out the siren.
The siren tamper will cause an error to be displayed on all keypads. Entering * 4 will display the error
condition.
