Commercial Facility Uses of Heat Detectors |
Purpose |
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. |
