I have a 449CT smoke detector that is connected to my electrical system. It is chirping. I can't just disconnect it and leave live wires exposed. Should I get a new one and replace it? Is there a way to turn it off so it stops chirping?

Hi .......what you have there is an integrated system .......meaning if one is effected then they all are so if you treat one you need to have the same remedy for all so........

Disconnect each smoke detector……. if they are hard-wired leave them disconnected…... you’ll un-plug the wiring harness connector at the back of each……... if they also have a battery, remove each and click the "Test" button for approximately 20 seconds to discharge the internal capacitor…….. once each smoke has been disconnected from power, listen if the chirping goes away or if you still hear it.

If only a battery connected, remove each battery and hit the "Test" button for approximately 20 seconds.............again to discharge the capacitor...........once this is completed, kill power to the circuit breakers completely to the OFF position............. then it dust off each with a compressed air canister (like the one you use for your computer) wipe with a soft cloth and install fresh batteries in each and replace………..Please let me know

Thanks
