10.7.2 Double Interlock Zone Releasing
A Double Interlock Zone uses a minimum of two addressable detectors, a designated manual release switch, and
an interlock switch input. An interlock switch is typically a dry-contact pressure switch and will be referred to as
an interlock/pressure switch in this document.
Conditions Required for a Interlock Release Alert Output Activation
If any single addressable detector is activated, the “Interlock Release Alert” output will activate. This alerts the
user that the initial stages required for a release condition are present. (Also refer to Table 10-5).
Conditions Required for a Detector Alarm Output Activation
If two addressable detectors, a manual release switch is activated, or an interlock switch is active, the “Interlock
Release Alert”, and “Detector Alarm” outputs will activate.
Conditions Required for a Interlock Release Alarm Output Activation
Any release requires the activation of an interlock switch, and either a manual release switch or 2 activated
addressable detectors. When these conditions are met, the “Interlock Release Alarm” and “Detector Alarm”
outputs will activate, and the “Interlock Release Alert” outputs will deactivate.
