Testing of Firefighters’ Emergency Operation

Test 1: Elevator not at the fire recall floor on automatic service and the hall doors disengaged from the car door, e.g. hall doors closed and car door open. Initiate Phase 1 recall via lobby switch.

Result: Car will not recall.

Test 2: Elevator is recalled normally on Phase 1 to the recall floor, then Phase 2 is initiated and elevator is placed away from the recall floor on phase 2. Hall doors are disengaged from car door e.g. hall doors closed and car door open. Place car call to another landing.

Result: Momentary pressure of door close button allows the car doors to close and elevator runs to floor where car call is placed.

Test 3: Elevator on Phase 2 away from the recall / designated floor. Hall doors closed and car doors open. Phase 1 key-switch in the on position. Turn off Phase 2 key switch.

Result: Car door should close to initiate Phase 1 return.

What You Need to Know About the Retroactive Mandated Door Lock Circuit Monitoring Code

NYC Building Code 3.10.12

3.10.12 Is a new addition to the NYC building code. It states its purpose quite clearly with this opening statement:“System to monitor and prevent automatic operation of passenger and freight elevators with faulty door contact circuits.”


Its mission statement is clear:“All automatic passenger and freight elevators shall comply with this section by January 1, 2020. Means shall be provided to monitor the position of power-operated car doors that are mechanically coupled with the landing doors or power-operated car doors with manually operated swing-type hall doors, while the car is in the landing zone.”


Notice the phrase “monitor the position of power operated car doors”.

This is a clear indication that the folks who wrote the new code requirement were aware of the fact that no monitoring can be accurately done without knowing what position the doors are in while in the landing zone.

The phrase also implies the requirement to monitor the second door connected to the drive door via an air cord, since “car doors” is plural. Two Speed and Center Opening doors would fall into this category.


(a) To prevent the operation of the car if the car doors are not closed (see Section 3.4.2(c) of ASME A17.3), regardless whether the portion of the circuits incorporating the car-door contact or the interlock contact of the landing door coupled with car door, or both, are closed or open, except as permitted under any of the following conditions:(1) by a car-leveling or truck-leveling device(2) when a hoistway access switch is operated(3) when the top-of-car inspection operation

utilizing a car door bypass or hoistway door bypass switch is activated


(b) to prevent, except as permitted by inspection operation, the power closing of the doors if the car door is fully open and any of the following conditions exist:(1) the car-door contact is closed or the portion of the circuit, incorporating this contact is bypassed(2) the interlock contact of the landing door that is coupled to the opened car door is closed or the portion of the circuit, incorporating this contact is bypassed, except when operating during Firefighters’ Service Phase II

Exception: For swing-type door operation, the locking (secondary) contacts shall be monitored.


(3) the car-door contact and the interlock contact of the door that is coupled to the opened car door are closed, or the portions of the circuits incorporating these contacts are bypassed;


Design and/or controller modifications shall be approved by the controller manufacturer or a registered design professional. Notwithstanding any inconsistent provision of chapter 1 or title 28 of the Administrative Code, the work required to comply with this section may not be performed without a permit from the department.

ASME A17.1 Code Requirements

Now that we have reviewed the NYC Building Code requirements there are also the additional requirements placed on all the city elevators in the form of the ASME A17.1. national code.

Paragraph 2.26.7 of that code, prohibits the installation of capacitors or other devices the operation or failure of which will cause an unsafe operation of the elevator.

It further states that no permanent device that will make the traction-loss detection means or any required electrical protective device ineffective shall be installed except as provided in 2.7.6.5.2(h), 2.12.7.1, 2.26.1.5, 2.26.1.6, and 2.27.3.1.6(c).

ASME a17.1 Code Requirements

This part of the ASME code is very clear. No device is allowed to be hung off the safety circuits, including but no limited to the gate switch and door locks.

If a device is attached to the safety string it is in violation of the ASME code and must be removed.

While this method may seem to some an efficient means of complying with the new code requirement, it is prohibited for obvious reasons.

Inspection Check List

Understanding the Inspection Checklist:Part I – Information & Signatures

Understanding the Inspection Checklist:Part II – Checkboxes

Inspection Procedure

Step 1: Verify Door Open Limit OperationPlace the elevator at a landing and put the car on car top inspection. Open the car door/gate fully and verify that the “OL1” and “OL2” relays drop out. Manually close the door and verify that the “OL1” and “OL2” relays energize.


Step 2: Verify Door Close Limit OperationWith the car door/gate closed verify that the “CL1” and “CL2” relays de-energize. Manually open the car door/gate fully and verify the “CL1” and “CL2” relays energize.

Note: For Otis elevators equipped with a “7300” AC door operator the “CL1” and “CL2” relays will work opposite of the operation described above.


Rational For Steps 1 and 2Since the Hall Door and Car Door/Gate monitoring is determined by comparing the limit condition with the position of the doors, the limit operations become critical to this process. Their operation must be verified so a baseline operation can be drawn.


Step 3: Landing Door Interlock TestWith the landing door and car door/gate opened, jump the landing hall door interlock contacts at the landing the elevator is stopped at. The door should remain opened and the strobe light indicator mounted on the MonIdor cabinet should engage showing a fail has been detected. Observe the car door/gate; it should not close. Repeat at top, bottom and one intermediate landing. Remove the landing door jumper and cycle the “Car Top Inspection Switch” to the “On” then “Off” position, or cycle the main line to return the car to service.


Step 4: Car Door/Gate Contact TestWith the landing door and car door/gate opened, jump the door/gate contact at the car. The door should remain opened and the strobe light indicator mounted on the MonIdor cabinet should engage showing a fail has been Detected. The car door/gate should not close. Remove the car door/gate contact jumper and cycle the “Car Top Inspection Switch” to the “On” then “Off” position, or cycle the main line to return the car to service.


Step 5: “Hall Door Bypass” Switch TestTo test the “Hall Door Bypass” switch function, place the car at a landing and move the “Hall Door Bypass” switch to the “Bypass On” position. Observe the “Bypass Active” LED, it should be illuminated. Verify that the elevator controller has been placed on inspection and will not run in automatic or controller inspection mode. Proceed to the car top and verify the elevator will run on inspection from the car top with the hall door opened. This cannot be verified from the machine room. It must be verified from the car top through the use of the car top inspection station.


Step 6: “Gate Bypass” Switch TestTo test the “Gate Bypass” function, place the car at a landing and move the “Gate Bypass” switch to the “Bypass On” position. Observe the “Bypass Active” LED, it should be illuminated. Verify that the elevator controller has been placed on inspection and will not run in automatic or controller inspection mode. Proceed to the car top and verify the elevator will run on inspection from the car top with the car door/gate opened. This cannot be verified from the machine room. It must be verified from the car top through the use of the car top inspection station.


Step 7: “Jumped Door/Gate Contact” TestPlace the elevator at a landing and hold it there with the doors opened. Place a jumper on “A1” and “A2” terminals of the MonIdor unit. The strobe light and audible signal mounted on the MonIdor cabinet should engage showing a fail has been detected. Remove the jumper and cycle the main line to reset the system.


Step 8: “Fire Service Operation” TestRecall the elevator and place it on Phase II operation. Run the car to any landing and open the doors. Once the doors are opened, split them and close the hall door. No fail should be detected when the hall door interlock engages. Turn the Fire Service key switch to the “Off” position and allow the Elevator to recall. If the Elevator recalls normally, the test has been completed successfully.


Completed Inspection Check List:Once the check list has been satisfactorily completed, the header should be filled out to include the Company, Installer, date of install, Building Identification Information and the City Serial Number. This document must be left in the plastic jacket affixed to the MonIdor cabinet cover as per the DOB’s request.
