Kidde Firex Hardwired Smoke Alarm - I4618 Contractor Pack, 4-Piece

False alarms at 2:00 a.m. these trigger randomly at 2:00 a.m. no fire no nothing alert it. We pressed the buttons to hush and then reset them all and they still go off. We then went to a 24-hour supermarket to get new batteries, replaced all the batteries and it still goes off. Had to get the fire brigade out due to CO2 concern. Nothing. There has to be far better products than these. This has happened more than once. We replaced batteries every 6 months and check test them regularly

Just moved in house. I have 3 of these, maybe 2 months old at the most. Had to remove one because it keeps going off. Not chirping, alarming for 5 seconds then quit. Horrible.

We live in a 2005 home we rent and had nothing but issues with these my husband had to uninstall all but 2 because it would randomly go off at night and last night 3/16/2025 the one in our room went off for no reason! 3 loud beeps 2 times and stopped obviously no fire we checked or smoke..it was 2am scared our 6 year old daughter and me my husband is uninstalling the other 2 and I'm going to get better ones that aren't wired in these are JUNK!!!! DONT BUY!!! and no I will not contact your customer service for new ones!!!!

Brand new house. Brand new smoke detectors. 2 of them are randomly giving off alarms. Not impressed with these. Had kiddie brand in our old house and we'd have them go off for no reason too. It's 2025, you would think we would have perfected smoke detectors by now.

Please seek alternatives. Late 2024 new home build features four of these miserable units. From installation, battery life has only been 6-months. False alarms a frequent problem despite vacuumizing & canned air flushing of the units. Product does not allow for longer lasting lithium batteries, ensuring "chirps," usually around 3:00 AM as the battery fails. Removing the battery will not stop the "chirp," as it's designed to sound if you try to leave the battery out of the unit.
