Q:When smoke detector goes off how can you shut it down quickly to limit the noise. I have a kidder firex hardwired smoke detector and when it went off it took about 15 to 20 minutes to shut off.

Answer This Question

A:  Hello. For this model, find the alarm that is giving a red flash every second while the alarm is going off. This is the alarm setting off all of the others. Unplug that alarm and the others will stop. Find out why the alarm is going off and what is going on in that location before you stop the alarms. For more information, please call us at 1-800-880-6788

          I am pleased with the alarms which detect not only smoldering fires but also large flaming fires. I also purchased the alarm adapters which allowed me to easily connect the new alarms to our current units (from BRK). My only issue with the alarms is that the alarm unit itself does not easily attach to the plate that is screwed to the ceiling. On every one the little pegs do not seem large enough to catch on the lip that holds the two pieces together. Consequently, the unit hangs loose from the ceiling. A couple of times I walked into a room to find the unit dangling by the wires. It was difficult (and frustrating) to attach the unit to the plate while standing with your arms above your head and trying to slide the unit until the pegs caught under the lip. seems to be a manufacturing defect that needs to be corrected..

          Concise easy to follow instructions with these detectors. Easy to install to existing wiring replacing my 20 year old Firex units. I placed 3 of these dual sensor units in the 3 main sleeping areas and a 6-pack of ionization sensors in other areas of the house. I feel better about having new detectors vs. 20 year old ones. The only downside to these units is that they must be removed from the mount to change the battery.

          I did research online and they recommended both ion and photo detection as best. I installed 9 and by the 3rd day one went off (falsely) at 3 in the morning. I thought maybe a bug or something, next night same thing. Disconnected that one. 2 nights later another one goes off falsely. Two nights later a third. Called Kidde and they said you need to clean them, I said there brand new, they said you probably have uneven electric power. I said you can have them back. Luckily Home Depot has a good return policy. Bought detectors with only photo and after a month so far no false alarms.

            120V W/ 9V Back-up with Easy Install Wire Harness
            Needed to replace an old unit. This was very easy to install. Simply mount the plate on the electrical box and then hook up the wire harness. Plug the wire harness into the unit and a slight turn attaches it to the mounting plate. Not only is this 120Volt that can be wired in sequence with other units, but it also has a 9 volt battery back-up. The ease of mounting and the wire harness will make it quick and easy to replace the battery as well. It also looks nice on the ceiling.

            Seem to be fine. Replaced 16 year old units that kept ‘chirping’. Husband had to modify some wires, but installed pretty quickly.
