The Technical Standards and Safety Authority (TSSA) has issued a Director’s Safety Order on Smartrise SRA (V3 CEDES) Controllers with single door zone sensor.
 
This order applies to elevators:

• with a Smartrise SRA (V3 CEDES) traction controller;
• registered and installed using CSA Standard B44 Elevators and Escalators; and
• with a single sensor to determine position for the levelling and Unintended Car Movement Protection safety circuits.

Safety Concern
This Director’s Order addresses a safety issue that could result in serious injury or death. During a Category 5 test on a traction elevator equipped with a Smartrise SRA (V3 CEDES) controller, CEDES Absolute Positioning System, and a single door zone sensor (sensing the position 75 mm above or below a landing), a mechanic observed that a single door zone sensor (either Magnet or Optical) can fail, and the elevator may move with the doors open. The car travelled toward the nearest landing with both the hall and car doors open, before stopping at the landing. The failure of the single sensor was not detected.
 
Actions Required
All owners and licensees shall ensure that their elevators are:

• Assessed in accordance with section 2 not later than June 1, 2025; and
• Have software altered and submit a Minor A Alteration Design Submission in compliance with section 3 of this order not later than December 1, 2025, where applicable.

Elevators not in conformance with the timelines above shall be removed from service until the required actions are completed.

Applications submitted after February 1, 2025, without mandatory documents will not be processed

To enhance the efficiency of processing design registrations for Elevating & Amusement Devices and Ski Lifts (EDAD Ski), design registrations submitted after February 1, 2025, without mandatory documents will not be processed.

TSSA reviews designs for EDAD Ski to ensure compliance with the Technical Standards and Safety Act and any other applicable regulations or adopted safety codes and standards. 

Submitting mandatory documents along with the application is critical to ensure the timely processing of design registrations. Please ensure that mandatory documents are complete.

During a Category 5 (CAT5) safety test on a traction elevator equipped with a Smartrise SRA (V3 Cedes) controller, SRA with CEDES Absolute Positioning System, and a single door zone sensor, a potential safety concern was identified:

1. The single door zone signal can fail, and the elevator may run with the doors open.
    
2. Unintended car motion will not be detected as the system believes the elevator is always within a door zone. Further testing of the Unintended Car Movement Protection revealed that the car could drift 2438 mm (6-8 ft.) before stopping and does not meet the maximum 1220 mm (48 in.) required by Unintended Car Movement Protection.
    
3. No injuries were reported. 

Smartrise has issued a mandatory Technical Service Bulletin - TSB-0016 on December 10, 2024. TSSA is actively working with Smartrise to identify and implement a solution to address this issue.

TSSA is developing a Director’s Safety Order, planned for dissemination in early 2025 to recommend appropriate corrective actions. Industry consultation will follow.
