HOW TO DISABLE A POINT
CAUTION
DISABLING A POINT CAUSES THAT POINT TO NOT REPORT ALARM CONDITIONS OR OTHER
STATUS CHANGES. A POINT SHOULD NOT BE DISABLED UNLESS IT IS CLEARLY UNDERSTOOD
THAT FIRE DETECTION OR SECURITY FOR THE AREA OF THE BUILDING COVERED BY THAT
POINT WILL BE LOST. APPROPRIATE STEPS MUST BE TAKEN TO PROVIDE ALTERNATE MEANS
OF PROTECTION FOR THAT AREA OF THE BUILDING WHILE THE POINT IS DISABLED.
If a device does not reset, you may disconnect the device/point causing the alarm condition. However, this point
must first be identified. Press the <ALARM ACK> key, and read the alphanumeric display on the interface panel.
Then disable the identified alarm point with the <DISABLE> key. If the <DISABLE> key is passcode protected,
perform the Log In Procedure before performing the Disable Procedure.
The <DISABLE> key press removes power to any displayed monitor point. Thus, disabling a point causes a trouble
condition on the individual zone.
To disable a point, perform the following procedure.
1. Open the interface panel access door.
2. Press the <ACK> key until the point to be disabled is shown on the alphanumeric display, as shown below.
