Elevator Recall System |
 |
Description and Purpose
Elevator Recall Systems allow
fire alarm systems to send an elevator car to a selected floor based
on the triggering of a
smoke detector within a fire alarm system. In addition, the recall
system may also include a
heat detector at the top of the elevator shaft,
pull stations at each elevator lobby, and other triggering devices. In
the elevator control room, system relay modules trigger elevator control
connection inputs to direct the elevator car to the specified floor. The
relay modules trigger when the fire alarm system activates.
The maximum number of elevators or floors
that the system can operate depends on the
control panel you choose.
Different elevators can be directed to
different floors depending on the device that is activated.
In addition to recalling the elevator, the
system can
release fire barrier door holders, allowing them to close until the
all-clear signal is given. |

Solving Recall Control Issues
In the event of a fire alarm, building codes
may require that the elevator car be automatically sent and held at a
particular floor. The system integrates with elevator controls to recall
the elevator car to the specified floor in the event of an alarm
Elevator recall must occur at the instant a fire alarm sounds, delivering existing passengers to the evacuation
point and blocking access to elevator functions until the all clear signal
is given. The system responds quickly to fire alarms or other critical
events in the safest manner.
In addition to recalling the elevator,
building codes may require that fire barrier doors be released to block
entry into the elevator. The system can release door holders so they
can automatically close.
Placing the elevator back into service after
an alarm has been reset must be performed quickly to clear slowed traffic.
The system instantly restores service as soon as the fire alarm resets.
Your design may impact cabling between the
control room and the car: Your application may require installing
devices or connecting to devices located inside of the car. This may
require use of conductors within, or replacement of the traveling elevator
control cable. Contact the elevator manufacturer or service company to
coordinate connections to devices located inside of the car.
