Avoid supply chain issues
I am far from installing them as I am just roughing in the electrical. I bought them now to avoid potential supply chain issues in May. They are rated amongst the best and there seem to be a sparse choice of hardwired heat/rate-of-rise alarms

Safety in the Garage with Heat Alarm
This heat alarm was very easy to install and set up. It is hardwired, but also has battery back up in case of a power outage. This is being used in a 2 bay garage. So two cars plus all the other items normally in a garage. Potential fire hazard, so with this alarm the family and home are protected and warned early if fire breaks out in the garage.

I had a Smoke / Carbon detector installed near my kitchen which would go off repeatedly whenever I cooked anything. I replaced it with this fire detector and it works perfectly. Highly recommended. The company shipped the product immediately so the customer service is great too

My first HD6135FB lasted the promised 10 years being manufactured in 2011. Ordering from First Alert was easy. Installation was also easy. A quick unplug of the old unit, replace the mounting base piece the new unit was slightly larger than the old one plug in the new unit, Test as identified in the instructions and I was good to go, The entire process including reading the manual took less than half an hour.

Garage Heat Detector Replacement
Replaced a 10 year old detector with this device. I ordered on line, arrived quickly. The new unit was a perfect replacement & functioned within the existing system.

Great Price, Fast Shipping & Delivery
Ordered this for our garage now that we've got a hybrid car that's occasionally plugged in overnight to charge. Buying this direct from First Alert got me the best price available on-line significantly less than big-box retailers and other sellers. Received a 9V Duracell battery along with the detector, which saved me a trip to the store for a backup battery. Installation and wiring was straight-forward. Alarm is quite loud - if there's a problem in your garage, you'll definitely hear it! Strongly recommend for garages and any other storage areas subject to significant temperature changes over the course of the year.
