33.3 Fire
Fire Phase 1 and Phase 2 allows for controlling a car(s) during a fire situation.
Fire Phase 1 – Smoke has been detected and Fire Phase 1 is activated manually (by key or
switch) or automatically (smoke sensor). The car(s) moves to a designated landing with car
doors open. If the landing is where the smoke is detected, the car(s) moves to an alternate
landing. In case the fire is in the machine room, the shunt operation removes main power to
the controller. The MR board activates an external shunt disconnect device after the car has
moved to the designated recall floor and doors are open.
The shunt operation is as follows:
• Smoke sensor activates.
• The car(s) move to the recall floor and open the doors.
• The shunt output activates and opens the Shunt Bypass switch, removing power to the
main disconnect.
Fire Phase 2 – A key switch is used to allow fire fighters or emergency personnel to gain control
from inside the elevator.
