FACP · Panel display
ALARM: SMOKE DETECTOR
ELEV LOBBY L3 · ADDR 118 · RECALL: NO RESPONSE
What you find on arrival
You activate the 3rd-floor elevator lobby smoke detector. The panel alarms and NACs operate, but the cars do not recall to the designated level. The elevator technician says his controller 'never saw the recall input.'
What do you do?
Life-safety function failed with the elevator contractor waiting. How do you find out where the recall command was lost?
