2020 Door Lock Monitoring: This code states that by January 1, 2020 all automatic passenger elevators shall provide a system to monitor and prevent automatic operation of an elevator with a faulty door contact circuit. All controllers built to meet the A17.1-2000 Code effective 2009 should have the door lock monitoring provisions built in. However, in 2016 the NYC DOB issued a service update bulletin stating that all existing elevators must comply with ASME A17.3 and NYC DOB K3 Rule 3.10.2. This update included modifications to Fireman’s Service operation which many elevator controllers did not have provisions for.
2027 Single Plunger Brake: This code states that by January 1, 2027 all elevators with a single plunger brake will need to be replaced or modified with a secondary brake mechanism (rope gripper).
