Alarm Inputs

For plug-in units, connections to the alarm panel are made by the two connectors

which protrude through the base. When fitting the unit, check that SK1 pins 1 to

8 and SK2 pins 9 to 16 correspond to pins 1 to 8 and 9 to 16 on the alarm panel.

The signal present on each pin is as follows:

SK1 Function SK2 Function

Pin 1 Alarm Input 1 Pin 9 +12V

Pin 2 Alarm Input 2 Pin 10 0V

Pin 3 Alarm Input 3 Pin 11 Not Used

Pin 4 Alarm Input 4 Pin 12 +5V

Pin 5 Alarm Input 5 or 7 (see below) Pin 13 Not Used

Pin 6 Control Output Pin 14 Alarm Input 6

Pin 7 Not Used Pin 15 Line Fault (output)

Pin 8 Low battery (input) Pin 16 Alarm Input 8

Alarm 5 can be transmitted as either channel 5 or channel 7. This is achieved by

fitting LK2 in either position 5 or 7. This link is not fitted on the stand alone units,

as alarms 5 and 7 can be transmitted independently.

For stand alone units, alarm inputs must be connected to the alarm panel

outputs. An eight way (three way for –24V) terminal block (TB1) is provided for

connection of the alarm inputs.

For 11zstu, alarm inputs for channels 9, 10, 11 and AC Fail are made at the

terminal block TB1 on the expansion board. Connections for alarm inputs 9, 10,

1 2 ... 9 10 11 12 13 14 15 16 17 18 19 ... 32 33
