Edwards AE Bulletin Elevator Recall & E-FSA Update

AEBN 020812 February 8 2012 Elevator Control and E FSA Addressable Panel Update bulletin is an update to a previous one AEBN 022410 describing how you can perform control using the Edwards E FSA addressable fire alarm system review The idea behind elevator recall is to bring the elevators to the lowest safe floor for during a fire so that people on the elevator do not step out into a smoke filled lobby This also make the elevators available to emergency personnel To accomplish this smoke are located in the elevator lobbies of a building If one of those smoke detectors alarm elevator will be sent to the proper floor That floor will depend on which smoke detector into alarm example if a smoke detector in the lobbies of the upper floors 2 and above alarm the will be recalled to the designated primary level usually the first floor If a detector in elevator lobby of the designated level alarms the elevator will be recalled to an alternate usually the second floor In addition to smoke detectors in lobbies detectors are installed the elevator machine room and sometimes elevator shaft which also recall the elevators machine room and shaft smoke detectors will also turn on a visual warning signal hat located in the elevator or elevator lobbies indicating the elevator is not safe to All these smoke detectors would be programmed to activate relays located in the elevator room that are used to control the elevators and turn on the warning light buildings where the elevator shaft and or machine room is protected by automatic sprinklers a trip circuit breaker is required to disconnect power to the elevator prior to the sprinkler in these areas activating This is initiated by a heat detector located near the sprinkler head in some cases a waterflow switch with no delay to insure the elevators shut down to prevent further use of them The heat detector s or waterflow switch then activate a relay also in the elevator machine room used to trip the breaker In addition the power used to the shunt trip breaker must be supervised The sprinkler system itself would also have to monitored by the fire alarm panel following will show a description of operation a recommended parts list and programming using the FSA CU configuration utility program Signaling Part of UTC Fire Security 9 Farm Springs Rd Farmington CT 06032 800 336 4206 Web www edwardssignaling

general alarm using Correlation Group 1 figure 2 Actual Correlation Group numbering be different than what is used here Correlation Group 2 figure 3 will be created for alternate floor recall and will include SE smoke detector in the first floor elevator lobby and the RA alternate floor recall When this smoke detector activates the elevator will be recalled to the alternate Correlation Group 3 figure 4 will be created for primary recall and will include all the smoke detectors on floors 2 and up plus the primary floor recall relay RP When any of these smokes activate the elevator will be recalled to the primary level Smoke detectors in the elevator machine room SM and elevator shaft SS if used will added to Correlation Group 2 or 3 depending on which floor the elevator should be to first floor in this example figure 4 a heat detector is located in the elevator machine room HM and or elevator shaft Correlation Group 4 figure 5 will be created which will include these heat along with the RS elevator shunt trip relay Activation of any of these heats break power to the elevator Note if a delay is required to bring the elevator to the recall level prior to the shunt trip this can be set from 0 to 300 seconds in Correlation Group 5 figure 6 is used to activate the elevator warning light relay RW if elevator machine room SM or elevator shaft SS smoke detectors alarm The module M will be configured as a supervisory input and wired to the K relay closed open while energized contact The relay coil will be powered from same source used to activate the shunt trip breaker The smoke detectors in the elevator lobbies machine room and shaft along with the heat shown will also usually be part of Correlation Group 1 for general alarm The relays for elevator recall warning and shunt trip will not be included in Group 1 List using E FSA system Fire alarm panel E FSA64 or E FSA250 addressable panel Smoke detectors for elevator lobbies machine room shaft E PD plus B4U base Heat detectors for elevator machine room and elevator shaft E HD plus B4U base or wired to E IDC1B or E IDC2B module E HD configured for fixed temp Module for sprinkler monitoring E IDCWS Note Waterflow input has a built in non 16 second delay If a delay is not desired you can use an E IDC1B or E module configured for Alarm input device type Addressable relays for elevator recall warning and shunt trip E RLY Note if load contact rating of E RLY you will have to interpose a second relay with higher ratings Monitor module M for shunt power relay supervision E IDC1B Relay for shunt trip

NFPA 72 National Fire Alarm Signal Code This bulletin was written to describe one way to implement the most common of elevator control using the Edwards E FSA addressable system Signaling Part of UTC
