I hooked it up which was very easy since I already had an old hardwired unit in place. I tested it by lighting a small wad of lighted newspaper in a pie tin and held it under the unit. Very easy to install and the battery box was well marked with + and - terminals. I replaced an old harwired alarm with this model and it works great. Installed it in 5 minutes and it still connects with my other alarms. This is a newer model because it has both photoelectric and ionization sensors.
Dual Sensors Detect Two Kinds of Fire
AC and AC/DC units will have a power indicator light that shines continuously when they are receiving electrical power. The same fuse or circuit breaker must power all interconnected alarms.

Even if the alarm sounded briefly when the battery touched the terminals, you still need to make sure it is snapped securely in place.
They came pretty fast & out daughter's boyfriend put them up. Only problem one of the alarms needed different batteries, so I suppose the other 2 will follow. I purchased this model because of the dual smoke detection features plus the carbon monoxide and I am happy so far with the product. If you have any doubts or reservations about these interconnect requirements, please contact an experienced electrician to install your wiring and hardwired alarms. I feel safer because they are designed to quickly detect both flames and smolders.
Connect to Other Alarms for Greater Coverage
If batteries are stored, especially in cold areas like refrigerators, they lose their charge more quickly. Always check the freshness date on the package when buying new batteries. Keep plenty of replacement batteries on hand so that you are sure to always be protected by your smoke alarms. We needed to replace our 3 smoke alarms so I contacted you.
