Customer Reviews For The Hardwired Heat Alarm with Battery Backup

This is my second identical heat alarm after 10 years. I am using this in my two car garage. I have it connected to my hard wired smoke detectors in the house.

I purchased two heat alarms for my two car garage as one was chirping every 5 minutes. They were 7 years old and the batteries were outdated. I made the decision to just replace them as I had already replaced all the smoke detectors in my house and wanted them all new. I used a 6-foot ladder and replaced them myself. It was very easy to do with just a screwdiver. They look great now and match my white painted ceilings and walls in my garage.

finally stop the burnt toast alarm

Order was a little slow but the product is great! Easy to unbox, everything was there and just as ordered. Mounting was easy as well as the wiring. Tested and verified units so all went surprisingly well! Would highly recommend.

Product was delivered very quickly and was exactly what I expected. Thank you

Just what I needed and quick delivery

Fast shipping and packaged well I will be placing another order soon

Items delivered promptly

I replaced the 2 alarms in my garage about 3 weeks ago. The First Alert Heat Alarms were still working perfectly but because they were 11 years old I decided to replace them. I received them very quickly and the install was simple, I was able to use the existing ceiling ring because the style of the new device fit perfectly. My entire house is hardwired with First Alert smoke and carbon monoxide alarms. I have called on several occasions and the customer support personnel are extremely helpful.

The product works as advertised. I installed one in the garage and one in the hallway. Many home fires start in the garage and we wanted to be woken up in our bedroom if the fire starts in the garage. The alarm in the hallway is loud enough for all occupants in the house can hear it and evacuate.

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

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

Needed this item for my garage. Arrived sooner than expected and got a good price and free shipping. So far so good. It is working.

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.

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.

no problem with service or product Would recommend

Have one of these in my basement and one in attached garage. Gives me peace of mind

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.
