If a device remains in alarm and no alarm condition (i.e., smoke or an activated pull station) exists,
the 4100 provides a way to inhibit alarm reporting for the malfunctioning point. Disabling a point
causes a trouble condition for the point or zone that you disable.
The <DISABLE> key, which is used to disable points, may be passcode protected. If it is, you
need to first log in to the system using the passcode that enables the key. Refer to “Logging In
and Out of the System” in Chapter 1 for information on doing this.
Be aware of the following issues related to disabling points.
• Disabling a point causes the 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 protecting the area of the building covered by the disabled point.
• If the Service Reset option is enabled, an operator can clear an alarm condition (i.e.,
successfully perform a system reset) even though the device that caused the alarm remains in
a trouble state. The typical application for this would be the case where a malfunctioning
initiating device such as a smoke detector (consisting of a base and removable sensor) causes
an alarm and activates the city circuit. With this option enabled, the sensor can be removed
and the system (including the city circuit) can be reset. Without this option enabled,
removing the sensor would cause a trouble, which would prevent the city circuit from being
reset.
Note: Service Reset is not a UL-Approved option and enabling this option on the
panel invalidates the panel’s UL certification.
To disable a point in alarm, follow these steps.
