Car Operation - Heat Detectors

This screen contains parameters that determine how the car will behave when one or more of
the heat detectors are activated. Heat detectors can be installed in the machine room, in the
hoistway, and/or on individual floors in the building. They are connected to inputs on an ICE-
MIAC board. Outputs from an ICE-MOR board are used to control audible and visual alarms
and well as to signal when heat detectors recall is complete.
• When heat detectors are activated, the fire warning light will flash until all heat detectors
have been reset. The fire-warning buzzer will sound until the car is shutdown at a floor. A
car that is parked at a floor will open its doors and shut down. A car in motion will proceed
in the current direction to the next available floor where the heat detector is not tripped. If
all heat detectors in the current direction are tripped, the car will reverse direction and
proceed to the first floor where the heat detector is not tripped. If again all heat detectors
are tripped, the car will proceed to the main fire recall floor unless the car is also on Fire
Service, in which case the car will proceed to the appropriate fire recall floor. Once the car
is stopped at a floor it will automatically open its doors and shut down. Then, if the
machine room or hoistway heat detectors are active, a signal is provided to disconnect the
main power line and/or activate the sprinklers where available.
• Heat detectors operation overrides fire recall operation: If checked, heat detec-
tors operation will override fire recall operation even if fire recall is already in progress
when the heat detector(s) are activated. If not checked, fire recall operation will take pre-
cedence unless heat detectors operation is already in progress or has completed and the
car has been shut down when fire service is activated.
