Works great. Perfect fit.
Bought this to replace the original 20-year old smoke detector. Perfect fit in the original wired mounting base. Sensor reset in alarm system cleared the trouble code.

Good sensor
This purchase was to replace an inoperative sensor. It works as design and was easy to install. I was disappointed the device didn't come with mounting screws, but luckily I retained the old one. I've had this device for over 2 months and there are no issues.

perfect replacement for 35+ year old 12 volt DC smoke detectors
Perfect replacement for 35+ year old alarm system smoke detectors. These do not have sirens in them. These are designed for 12 volt DC home alarm systems. I used these with a "Konnected" smart panel alarm system update. I have five of these installed. It is made for a four or five wire system. It is a "Normal OPEN" type of alarm. It closes when smoke or 135 degree heat is detected. You can test thermal sensor with a hair dryer.
