System Operation
Reduce detector spacing to 0.7 times the linear spacing in accordance with NFPA 72.
10.6.2 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 docu-
ment.
Conditions Required for a Pre-Alert Output Activation
If any single addressable detector is activated, the “Pre-Alert” output will activate. This alerts the user that the initial stages required for
a release condition are present. (Also refer to Table 10.3.)
Conditions Required for a General Alarm Output Activation
If two addressable detectors, a manual release switch is activated, or an interlock switch is active, the “Pre-Alert”, and “General Alarm”
outputs will activate.
Conditions Required for a Release 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 “Release” and “General Alarm” outputs will activate, and the “Alert” outputs will deactivate.
Reduce detector spacing to 0.7 times the linear spacing in accordance with NFPA 72.
NOTE:
Refer to Table 10.2 for approved releasing solenoids and ratings.
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.
Each Double Interlock Zone input requires at least one Interlock/pressure switch
