2 ATTACHMENT 1 List of Technical Requirements [LTR] LTR Number D [Elevating Devices] Subject Keywords Interlocks, Locking Devices and Electrical Contacts for Elevator Landing and Hoistway Doors and Gates Background & Rationale This List of Technical Requirements (LTR) replaces TIL CSA D-11B dated September 30, 2004, which has exceeded its prescribed period of validity and has not been incorporated into a standard. This LTR will be used until technical requirements are incorporated into a CSA standard suitable to be used for conformity assessment. 1.0 Scope Technical Issue 1.1 This LTR covers the following devices (hereafter referred to as Devices) for use in elevator systems within the scope of CSA B44 Safety Code for Elevators and Escalators: (a) (b) (c) (d) (e) landing and hoistway door interlocks, landing and hoistway door combination mechanical locks and electric contacts, landing and hoistway door locking devices and electric contacts, car-door interlocks, car-door and gate electric contacts, 1.2 This LTR does not cover devices for use only in lifts for physically disabled within the scopes of CSA Standards CAN/CSA-B Definitions 2.1 The devices covered in this LTR are defined in Section 1.3 of safety code ASME A17.1/CSA B Requirements 3.1 General A device shall comply with the applicable requirements of standard CSA B44.1/ASME A17.5 and the applicable construction and test requirements of safety code ASME A17.1/CSA B44-16 specified in Clauses 3.2, 3.3 and Construction A hoistway interlock (landing-door door interlock) shall comply with Clauses , , , (a) and (b), , and of ASME A17.1/CSA B44-16 Safety Code for Elevators and Escalators. The interlock shall be subjected to the contact bridge separating force test Page 2 of 5

3 3.2.2 A hoistway door combination mechanical lock and electric contacts shall comply with Clauses , , , (a), , and of ASME A17.1/CSA B44-16 Safety Code for Elevators and Escalators Landing and hoistway door electric contacts shall comply with Clauses and of ASME A17.1/CSA B44-16 Safety Code for Elevators and Escalators A car-door interlock shall comply with Clauses , ; , (a) and (b), , , , and (c) and (e) of ASME A17.1/CSA B44-16 Safety Code for Elevators and Escalators. The interlock shall also be subjected to the contact bridge separating force test Car-door and gate electric contacts shall comply with Clauses (b), (c) and (e) of ASME A17.1/CSA B44-16 Safety Code for Elevators and Escalators Openings in an enclosure shall comply with Clause 7 of standard CSA B44.1/ASME A , unless otherwise specified in Clause The test probe requirement of Clause 7.1, 7.2 and 7.3 of standard CSA B44.1/ASME A are not applicable to the openings provided in an interlock and door locking device enclosure for the engagement of a locking member. The openings may be more than the limits specified in Clause 7.1 of standard CSA B44.1/ASME A but shall be not more than the required dimension as determined when the locking member is in operation. 3.3 Marking The following requirements from clause of safety code ASME A17.1/CSA B44-16 shall be permanently marked on the device and shall be readily visible when the device is installed. (a) manufacturer s name or registered trademark (b) catalogue or model designation (c) rated voltage and current, and whether AC or DC (d) rated test force (e) rated test movement. (f) the certification/listing/approval mark of the certification organization (g) the indicator CSA B44 (h) date (month and year) devices subjected to type test (i) indication of the Date of Issue of the Code Applied (see Note below for details) (j) For Private Residence Elevator Only or equivalent, if the device has only been certified for use on a private residence elevator.

ATTACHMENT 2 Major Revisions Clause(s) (j) For Private Residence Elevator Only or equivalent, if the device has only been certified for use on a private residence elevator Notes Changes This marking requirement has been added. The Notes (a) has been deleted, (a) Misalignment tests specified in Clause of CSA Standard B44 are not required for devices within the scope of this TIL. These tests relate to specific use applications which must be verified by testing of the combination of the specific door and with the locking device A device shall be subjected to the misalignment test of clause of CSA Standard B Notes (b) The locking member disengagement tests specified in Clause of CSA Standard B44 are not covered by this LTR. These tests relate to specific use applications that must be verified by independent testing of the combination of the specific door and with the locking device Misalignment test from Clause of safety code ASME A17.1/CSA B44 has been added Notes (b) has been deleted. The disengagement test has been deleted by ASME A17.1/CSA B safety code. Page 5 of 5
