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:
- The single door zone signal can fail, and the elevator may run with the doors open.
- 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.
- 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.

The Technical Standards and Safety Authority (TSSA) has posted two new advisories on Elevating Devices to provide guidance to industry:
Federal Elevator Limited Use/Limited Application – Verification of Correct Shackle Assembly
This is an updated version of the advisory detailing requirements for a shackle washer on Federal Elevator Limited Use/Limited Application (LULA) Elevators. This advisory was initially shared on May 8, 2024, to inform owners and operators about the possibility of a suspension failure at the shackle connection to the elevator on Federal Elevator LULAs. Please read the updated advisory for details.
Minimum Vertical Clearance on Load Carriers for Parking Garage Lifts
This advisory is intended to bring awareness to the expected vertical clearance to be provided between load carriers for parking garage lifts. As a best practice, 2000 mm clear headroom between the load carriers of a parking garage lift shall be provided so users can safely enter and exit the working area of the parking garage lifts safely. Please read the advisory for details.
