Situations such as a malfunctioning detector causing false alarms, or an activated detector that
prevents the system from being reset, can be temporarily overcome by disabling that particular
point. Disabling a point allows the system to be reset while repairs are being made. It takes the
point “offline”. Disabling a point prevents the point from entering an alarm condition for the
duration of time it is disabled.
Follow these steps to disable a point.
1.
Select the point that you want to disable. Refer to Chapter 5 for information on
selecting points.
2.
Press the <DISABLE> key.
3.
Press the <ENTER> key.
The system generates a fault condition and message, indicating that the point is disabled.
Note: To disable a point that is in alarm, press the <ALARM ACK> key until the desired
point is displayed, then press the <DISABLE> key and the <ENTER> key.
Follow these steps to enable a point.
1.
Select the disabled point that you want to enable, e.g. by repeatedly pressing the
<FAULT ACK> key until the desired point is displayed.
2.
Press the <ENABLE> key.
3.
Press the <ENTER> key.
Note: The system displays a message indicating that the point will be enabled in 60
seconds. If the state of the device is such that an alarm condition will occur when the
point is enabled, the system warns you that this will occur. You can abort the enable
operation before the countdown timer expires by pressing the <DISABLE> key.
