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.
