Operation

(assuming the Abort Delay is set to 90 seconds)

When the alarm is activated channel 3 is triggered and the central station receive an alarm

signal. If the system is unset within 90 seconds the alarm output is cleared and the central

station receive a restore signal. This is interpreted by the central station as an abort signal and

therefore the system is NOT policed.

Using limited Open/Close

This form of alarm abort requires the signalling device to report open/close and the abort

output (071) to be connected to the open/close channel, this is normally channel 4 (see figure

below).

Operation

(assuming the Abort Delay is set to 90 seconds)

When the alarm is activated channel 3 is triggered and the central station receive an alarm

signal. If the system is unset within 90 seconds the abort output is activated and the central

station receive an open signal. This is interpreted by the central station as an abort signal and

therefore the system is NOT policed. When the system is next set the abort signal is

deactivated and the central station receive a set signal. If the system is unset without an alarm

present the central station will NOT receive an open signal, this will cut down the number

open/close transmissions as they are only reported when the alarm is aborted.

Using the Abort Channel

This form of alarm abort requires the signalling device to report the abort signal on a separate

channel (e.g., channel 7). The abort output (071) is then connected to this channel (see figure

below).
