Kidde P12040

The Kidde P12040 is a photoelectric smoke alarm powered by 120VAC and comes equipped with 9V battery backup. This advanced smoke alarm functions as a stand-alone unit or in an interconnected system.

Sensor Technology

The Kidde P12040 uses a photoelectric sensing technology that detects visible particles associated with smoldering fires sooner than ionization alarms. Ionization alarms detect invisible fire particles associated with flaming fires sooner than photoelectric alarms. Kidde recommends that both types of alarms be installed inside the home to protect against both types of fires.

Installation

The smoke alarm can be installed on any standard single gang electrical box, up to a 4” octagon junction box. The electrical connection (to the alarm) shall be made with a plug-in connector. A maximum of 24 Kidde devices can be interconnected in a multiple station arrangement. The interconnect system must not exceed the NFPA (National Fire Protection Association) limit of 18 initiating devices, of which 12 can be smoke alarms. With 18 initiation devices (smoke, heat, CO, etc.), interconnected, it is still possible to interconnect 6 strobe lights and or relay modules. The unit shall provide optional tamper resistance that deters removal of the unit from the wall or ceiling.

Alarm Conditions

The alarm shall include a test button that will electronically simulate the presence of smoke and cause the unit to go into alarm. This sequence tests the unit’s electronics, battery and horn to ensure proper operation. There is one red LED to indicate the alarm's current status and mode of operation. During the standby condition, the red LED will flash every 30-40 seconds to indicate the smoke alarm is operating properly. During the alarm condition, the red LED will flash rapidly (one flash per second). The rapid flashing and pulsating alarm will continue until the air is cleared from the products of combustion. The unit will also have one green LED to indicate the presence of power.

These go off in the middle if the night for no reason! Do not buy these. These we included in the new house we bought and through the years they would just, go off. And they would go off in the middle if the night each time. I was told that these are 12 years old so the went off because they are 'old'. So we replaced all of them.....well they worked fine for a year then at 1:30am one night they went off in the middle of the night again! This happened to be when my husband was out of town and scared me to death. So loud I didn't know what to do, had to figure it out fast because I was going deaf from the noise! Had to get the ladder out and unplug each of them. After I unplugged four of them, they finally stopped going off! Had the handyman come over the next day...as he was handling one of the ones I took off..it went off in his hands so he assumed that, was the bad one so he put the rest back in.
Well wouldn't you know iit....the next night same time I was in a nice deep sleep and thet went off again!!!!! I had to get the ladder out again and disconnect one of the ones form the night before and they stopped going off.
This is extremely frightening when they go off for no reason.do not buy this brand. We've been battling these alarms for years now. Horribly scary when the go off in the middle of the night for no reason and you have to unplug and then your not protected from a real fire! Ridiculous!!!

I bought ten Kidde p12040 photoelectric smoke alarms for my house. They all installed easily. After one month, one started chirping. I figured it must be defective, since the other ones were not chirping and all passed diagnostic tests fine. I bought another one (yes, an eleventh p12040) to replace the chirping one.

After six months, a different one started chirping. This time, I actually did a little research. According to the "P12040 Smoke Alarm User's Guide", section 4 "OPERATION AND TESTING", if the alarm chirps at the same time as the red led flashing, it means low battery. (If it chirps between the red led flashes, it means a component of the smoke sensing chamber failed.)

It turns out that this model smoke alarm comes with a cheap Carbon-Zinc battery (Kidde Gold Peak model 1604P) rather than a better Alkaline type or a best Lithium type. I assumed that the ten year warranty displayed on the box meant that the battery would last ten years, as some other models claim. Let the buyer beware.

So, my experience is that this model smoke alarm is fine after seven months of use, but expect to replace the battery. I intend to replace the batteries as they fail with Lithium type batteries.

Also, this model does indeed have a "HUSH" feature. According to the "P12040 Smoke Alarm User's Guide", section 5 "NUISANCE ALARMS", "The Model P12040 has a HUSH control that is extremely useful in a kitchen area or other areas prone to nuisance alarms." See section 4 "OPERATION AND TESTING", paragraph "HUSH CONTROL", on how to use it.

Our new house has 7 of these, all hardwired and interconnected. When one goes off, all do, and you race from room to room trying to see which one it is. We have had numerous false alarms, usually in the middle of the night, and Kidde customer service assured me it needed to be vacuumed and cleaned. We did, and by nightfall it happened again. We are now desperately trying to find a single brand that doesn't have a problem with false alarms, but all of the major ones seem to. I will never buy this brand again.

My house uses 6 of these devices. About 5 years ago at 4:30 in the morning on Thanksgiving the smoke detector alarm went off. I got up and smelled what seemed like an electrical fire. I dashed around the house and when I couldn't find what made the smell I called the fire dept. While waiting for them to arrive I unplugged all of the detectors since this is the only way to get the alarm to stop. One of the smoke detectors was the source of the electrical fire smell. Something had fried inside the detector. When the fire dept arrived I gave them the detector and their comment was they had never before seen a smoke detector mal-function like this. Imagine having to call the fire dept because of a faulty smoke detector. Anyway if this was a one off incident I wouldn't be writing this review. The same thing happened again a couple of weeks ago. The same model smoke detector fried and set off all of them. No fire dept. call this time though.

Spoke to Tech Support. There is no Hush Button on this Photoelectric model (and the Test Button does not act in this regard either).

Go with the BRK / First Alert, Model 7010B, which has the Silence Feature (for up to 15 minutes).

Options I was looking for:

Photoelectric - This is better than Ionization, in my case, where the alarm is just outside of a bathroom - where steam can set it off (I'm replacing an AC only, Ionization. Photoelectric is less sensitive to steam). Disposing of Photoelectric detectors after 10 years is also more environmentally friendly. They do not contain americium-241, which is under the positive plate of the Ionization chamber.

AC powered with 9V battery backup - The most desirable to have

Hush Button - The 9V battery backup will keep the alarm going, even if you cut power at the circuit breaker box - Need to be able to silence a false alarm, without having to remove the battery.
