|Commercial Facility Uses of Heat Detectors
|Elevator Power Shutdown
|Provide electrical safety prior to sprinklers activating (above 135F) and preventing failed egress (being trapped in elevator).
|Reduction in Fire Barrier Resistance of Construction Materials
|Retrofit application exception (old codes had lower time requirements for burn through).
|In Lieu of Smoke Detectors
|Exception based scenarios due to ambient (dirty) conditions in certain occupancies typically requiring Authority Having Jurisdiction or Engineer Design Approval (not an installer decision).
|In Lieu of Sprinklers
|Special circumstances in certain occupancies allow exceptions:
Non-occupied spaces (attics); no machinery present (e.g. HVAC equipment); apartment buildings, etc.
|For Releasing Door Locks
|Any detected alarm heat, smoke, or sprinkler water flow needs to release Access Controlled doors for egress.
|In Lieu of Manual Pull Stations
|Reducing manual false (intentional) alarms in educational gyms, auditoriums, and assembly areas.
