8.7.1 Single Interlock Zone Releasing
A single interlock zone utilizes a minimum of two addressable detectors and a designated manual release switch.
Conditions Required for an Pre-Alarm Output Activation
If any single addressable detector is activated, the “Pre-Alarm” output will activate. This alerts the user that the
initial stages required for a release condition are present. (Also refer to Table 8-3.)
Conditions required for an General Alarm and Release Output Activation
If two or more addressable detectors, or a manual release switch activate, the “Alarm” and the “Release” outputs
will activate and the “Pre-Alarm” output will deactivate. (Also refer to Table 8-3.)
Important!
Only addressable detectors can be used. No conventional detectors can be used.
Each Single Interlock Zone input requires at least one manual release switch.
