SUN - UL 634, Connectors and Switches for Use with Burglar-Alarm Systems
Effective June 1, 2016
Effective Date (see Schedule below): March 27, 2016
Impact Statement: A review of all Listing Reports is necessary to determine which products comply with new/revised requirements and which products will require re-evaluation. NOTE: Effective immediately, this revised standard will be exclusively used for evaluation of new products unless the Applicant requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date noted above, unless the product is found to comply with new/revised requirements.
Overview of Changes: This revision to UL 634 was issued to incorporate updates, revisions and clarifications for magnetically operated switches. Specific details of new/revised requirements are found in table below.
Schedule: So that shipping of products with Listing Marks will not be interrupted, an approximate schedule has been established to ensure Listing Reports are found compliant by Effective Date:
- August 3, 2015 = 7-8 Month Report Review – Intertek will review all Reports. Update if compliance is verified or issue Findings Letter/Quote for any re-evaluations needed
- September 25, 2015 = 6 Month Quote Cut-off – Quotes returned for necessary re-evaluations
- February 26, 2016 = 30 Day Warning – Client advised of all non-compliant Reports to be Suspended
- March 27, 2016 = Effective Date – ATM Suspended for all non-compliant Reports
Fees: An initial review of Listing Report (s) will be covered by a direct billing project and will be invoiced at not more than $1000 per report.
Client Action Required:
Information - To assist our Engineer with review of your Listing Reports, please submit technical information in response to the new/revised paragraphs noted in the attached or explain why these new/revised requirements do not apply to your product (s).
Current Listings Not Active? – Please immediately identify any current Listing Reports or products that are no longer active and should be removed from our records. We will do this at no charge as long as Intertek is notified in writing prior to the review of your reports.
| Clause | Verdict | Comment |
|---|---|---|
| 54 | Info | Compromise Test – Magnetic Switches (Level 1 and Level 2) |
| 54.1 | Additions to existing requirements are underlined and deletions are shown | |
| 54.2 | Additions to existing requirements are underlined and deletions are shown A portable test magnet is to be positioned next to the installed magnet and switch directly in the space above the drive magnet(s) a) Parallel to the installed magnet or switch on each surface and in the same magnetic polar orientation; b) Parallel to the installed magnet or switch on each surface and in the reverse polar orientation; c) In the plane of the door and perpendicular to the installed magnet or switch on each surface; d) In the plane of the door, perpendicular to the installed magnet or switch on each surface, and in the polar orientation that is the reverse of that used in (c); e) Perpendicular to the door and to the installed magnet or switch on each surface; and f) Perpendicular to the door and to the installed magnet or switch on each surface, and in the polar orientation that is the reverse of that used in (e). | |
| 54.3 | Additions to existing requirements are underlined and deletions are shown A magnet pole is to be placed on one end of a flat, magnetically sensitive steel plate | |
| 57 | Info | General (MARKING) |
| 57.2 | New clause added; Level 1 and Level 2 instructions shall be marked with the following information: maximum current, maximum voltage, maximum power, minimum intended operating gap, maximum intended operating gap, and indication of any special mounting conditions such as “ferrous mount only” or “ingress door only”. | |
| 63 | Info | Foreign Magnetic Field Tamper Alarm Test |
| 63.1 | Additions to existing requirements are underlined and deletions are shown | |
| 64 | Info | Foreign Magnetic Field Compromise Tests (Level 2) |
| 64.1 | Additions to existing requirements are underlined and deletions are shown In addition to conducting the compromise test using the test parameters outlined in 54.2, the compromise test shall be conducted within the gap between the switch assembly and the installed magnets. The test magnets are to range from 1/2 to 2 times the energy product, reference 54.4 and 54.5, and may be loose or affixed to thin strips of plastic and/or a) The compromise test shall be conducted using the same number of test magnets as contained in the actuator. b) The installation of the test magnets between the switch and actuator shall be conducted using ferrous and non-ferrous shunts when possible. c) The magnet specifications for the small magnet thickness (SMT) tests are outlined in Table 64.1. d) The ferrous shunt dimensions are outlined in Table 64.3. e) The magnet specifications for the large magnet thickness (LMT) tests are outlined in Table 64.2. f) The magnet and shunt combinations are outlined in Table 64.4. g) Up to 1/32 inch (0.8 mm) may be deducted from the maximum operating gap (MOG) thickness to compensate for the magnet placement holder. h) Magnets shall be used in incremental order from smallest in diameter/thickness to largest in diameter/thickness as incrementally referenced in the corresponding tables. i) When the BMS is defeated using multiple magnets placed in the gap between the switch assembly and the installed magnets, the additional test parameters using magnets, outlined in 54.2 are not required. |
