Worked right away after installation

I have 2 of these hardwired smoke detectors installed in my house from the builder, one of each floor. I think these are the beginning of the fire alarm loop, the rest of the detectors are wired in with a battery back up. The house is almost 18 years old and the two originals lasted until one went recently and it showed a fault in my alarm system. At first I thought I'd call the alarm company, but then I checked here on Amazon and found the exact match. I unscrewed the bottom part and screwed it into the original base. The base has no working parts, no lights, no chips, it's just a wire connector base, and it was identical. I screwed it in, cleared the fault on my alarm system, and the green light on this detector starting blinking to show it's active. So, thanks to Amazon carrying this, I saved the money of a call out visit from the alarm system monitor. Very happy, nice product, prior to this never had any issues.

Perfect replacement and upgrade of an original sensor

Original sensor was malfunctioning and these sensors work well as replacements. Slightly smaller than the originals, but identical wiring looms. Small light indicates whether the sensor is operational.. Successfully used in a run of 4 fire sensors attached to a Honeywell control board.

worked fine for DIY replacement

My house has these installed already by the builder 17 yrs ago. The code says they are good for 10 yrs so I had to bite the bullet and replace them. after calling many local vendors and all of them refused to sell to non-professional client like me, I took a chance and bought from AMZ. The vendor FIRE & SAFETY PLUS returned my inquiry w a mfg date of only 2 months ago do I bought from them despite the price being a little higher. They arrived in about a week and indeed the mfg date was accurate and all 8 detectors worked fine - a blinking green light appeared after installing. Installation was simple since I left the base plate with the wiring in place and simply twisted off each old detector and twisted on the new one. Glad I didn't hire a professional to do this simple task.UPDATE: MAY 2022We are required to get an inspection from the Fire Dept before selling a house in MA. When the FD arrived and tested some of these detectors, some of them took over a min before the audio signal is activated. Needless to say I did not pass the inspection. After they left, I tested each of the 8 detectors and MOST OF THEM had over a min delay. Only a few activated the audio signal instantly. This is where I really want to praise the vendor I used: Fire and Safety Plus. They were willing to send out 8 new detectors so that I can switch out the defective ones. I received the new badge within 4 days and were able to get 8 working detectors out of all 16. They provided a postage paid sticker so return shipping was free. So I highly recommend this vendor, even if they cost a few bucks more just in case you run into problems like I did.

Works with Napco alarm system w/2-wire smoke detectors

Works perfectly with my Napco GEM-P1632 alarm system monitored by a security company. I used these to replace an older System Sensor smoke detector that's no longer available. To test functionality, it's possible to buy cans of smoke detector test spray like "CRC-2105", but I was able to test it by twisting off the center cover, lifting off the black plastic piece under it, and putting a clean cloth over the photoelectric sensor to block the light for a few seconds. This may not be an "official" testing method, but it gets the alarm to ring.

Watch those Date Codes

Unit installed and works as it should Please note that I purchased these in January of 2024. The date code on the 2 units I purchased were 2081 (2022 August 1st Week). So not exactly fresh but given the 10 year life span they work. I wish more people would include the date codes in their review so as a consumer you can determine which seller is selling old but nor expired units. This is the main driver of the price. Right?
