All strobe products produced after October 22, 2021 will only meet UL 1638 and no longer meet ADA, FHA, HUD, and UL 1971.
Applies to all Kidde customers with orders pending or future orders for P4010ACLEDS-2, P4010ACLEDSCO-2, and SLED177i.
Background
Kidde was made aware of a change to the UL 1971 standard regarding the strobe light pulse duration to 20 ms (milliseconds).
At this time, the strobe light pulse duration on our products are ~50ms, consequently we have removed these products from our portfolio
Timing for updated products is approximately 6 months.
What should you do?
Unless a local ordinance specifies otherwise, any P4010ACLEDS-2, P4010ACLEDSCO-2 and SLED177i products produced prior to October 22, 2021 are NOT impacted by this transition. Therefore, anything already installed or in inventory still meets ADA, FHA, HUD, and UL 1971.
