PROBLEM TO BE SOLVED: To prevent fire-fighting activity from being inhibited by an abnormal action monitor for ensuring safety of elevator users.SOLUTION: When a primary fire-fighting operation switch 6 (an emergency operation switch) is switched to "ON" an elevator operation control means 9 executes primary fire-fighting operation control. Even if a door safety circuit short detection means 12 outputs an operation stop command during the primary fire-fighting operation, an abnormal action monitoring function nullifying means 14 cancels this (does not cancel an operation stop command from an open-gate starting prevention means 13). When a secondary fire-fighting operation switch 7 (an emergency operation switch) is switched to "ON" the elevator operation control means 9 executes secondary fire-fighting operation control. If either the door safety circuit short detection means 12 or the open-gate starting prevention means 13 outputs the operation stop command during the secondary fire-fighting operation, the abnormal action monitoring function nullifying means 14 cancels this. |
