HOW TO ISOLATE / DE-ISOLATE A ZONE

If a device will not reset, the user may elect to perform the ISOLATE procedures
listed below.
IT IS IMPORTANT TO REMEMBER THAT ONCE A POINT IS ISOLATED, IT WILL
NOT PROVIDE FIRE PROTECTION. REPAIR/REPLACE THE DEVICE AS SOON
AS POSSIBLE. ONCE REPAIRED, THE POINT SHOULD BE ENABLED AS
SOON AS POSSIBLE (See following, How To De-isolate an Isolated Point).
If a device does not reset, the user may isolate the device/point causing the
abnormal condition. This point must first be identified. This can be accomplished by
reading the alphanumeric display while pressing the <ACK> key. The point can then
be isolated by using the individual zone ISOLATE toggle switches as described
below :
1. Press down the ISOLATE toggle switch next to the zone or point to be
isolated - refer figure 3, e.g. ( AZF1 1st Floor East Wing Room 23 ).
Once the toggle switch has been depressed, the yellow ISOLATE LED
adjacent to the toggle switch will light ,indicating that the point or zone is now
isolated.
