FAQs
What are the required control panel configuration settings when installing an Elevator Recall system?
Control panel features and programming may vary depending on applicable local codes and when integrated with other fire protection systems (such as a sprinkler system). Consult with your AHJ for all local code requirements.
In general, Elevator Recall systems allow fire alarm control panels to send an elevator car to a designated floor when a system smoke detector is triggered. The recall system may also include heat detectors installed within the elevator shaft, pull stations installed in each elevator lobby, and other devices installed within the premises. When the fire alarm system activates, relay modules located in the elevator control room trigger elevator control inputs to direct each elevator car to its designated floor.
The control panel selected will determine the maximum number of elevators and floors the system can control. Each elevator can be directed to a selected floor depending on the device activated and its location. In addition to Elevator Recall, the fire alarm system may also be designed to close fire barrier doors until the "all clear" signal is given.
Zone Set Up
A smoke detector must always be installed inside the elevator control room. Each elevator lobby requires a smoke detector be installed within 21 feet of the elevator door center line. Heat detectors are only required inside the elevator if the premises is protected by a sprinkler system. The installation of smoke detectors and/or heat detectors within elevator shafts is only required if the premises is protected by a sprinkler system and if required by local codes.

Programming Relays
Program one relay for "primary floor" elevator recall and program a second relay for "alternate floor" recall. To prevent unpredictable elevator operation due to water discharge within an elevator shaft and/or elevator room, a third relay may be required for "elevator shunt" (the elevator's main power shunt trip breaker) if the shaft and/or elevator room are protected by a sprinkler system. The following image displays an example of the relay programming using PCD-Windows Quickloader:
Programming Relay Events
Program the first floor elevator lobby smoke detector to trip the "alternate floor" recall relay; program all other elevator lobby smoke detectors, elevator room smoke detectors and elevator shaft smoke detectors (if required) to trip the "primary floor" elevator recall relay. If installed, program heat detectors that are located in the elevator room, in the elevator shaft and shaft bottom to trip the relay connected to the elevator's main power shunt breaker.
