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

Please contact any customers that currently have a backorder with the impacted models and make them
aware these models are no longer listed under ADA, FHA, HUD, and UL 1971.
Unless a local ordinance specifies otherwise, any P4010ACLEDS-2, P4010ACLEDSCO-2, and SLED177i
products produced prior to October 22
nd
2021 are NOT impacted by this transition.
Therefore, anything already installed or in inventory still meets ADA, FHA, HUD, and UL 1971.
