Hello, I wish to confirm that the unit may in fact be hardwired. I have existing hardwired ionization smoke detectors, and due to state code am now required to utilize photoelectric, hardwired, battery backup smoke detectors (MA state regulations). Could you confirm that this unit will meet this requirement? Will I likely need to modify my wiring? I have existing three-pronged connectors for the current detectors. Thanks!

I have two of these alarms installed in my system. I noticed that only one will illuminate green at a time when they are inter-connected. Is this normal?
Asked by: Mike
The ambient light sensor in the unit probably thinks it's nighttime and defaults to not illuminating - this is a feature to make it more appealing for bedrooms. The unit tries to establish a day/night schedule over the first few days it's installed. I'm guessing that one of your rooms doesn't get enough ambient light to train it / help it learn night from day. They work just fine regardless of whether the ring glows green - it will still flicker very briefly about once/minute. Chances are, if you turn on enough lights or open the blinds you'll see it glow within a minute or two.

After about 10 days this unit started chirping and flashing Amber every 5 seconds. Silenced chirping by pressing center button. Still indicating fault. Is there any way to reset/clear alarm on this unit?
Asked by: Catman
I'm betting that either it isn't networked with the other units or it isn't getting AC power - either it isn't wired correctly or the existing lines you used were not live to begin with. The fault from the Amber flash blinks an error code to identify the problem - Page 7 of the user manual outlines the various causes for the Amber flash and advices to push/release the Hush/Test button and count the number of Red LED flashes - the blinked error code will indicate the problem and you can contact Kidde customer support for advice on how to fix it.
