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

activated addressable detectors. When these conditions are met, the “Release” and “General Alarm”
outputs will activate, and the “Alert” output will deactivate.
