This unit is interconnectable with other units of the same like. The interconnect system must not exceed the NFPA (National Fire Protection Association) limit of 18 initiating devices (smoke, heat, CO, etc) interconnected. It is still possible to interconnect 6 strobe lights and or relay modules in addition to the 18 initiating devices. This unit is UL Listed. Consumer benefits The Kidde HD135F provides you and your family an early warning to dangerous temperatures greater than 135˚F. This unit also includes a tamper resist pin to deter tampering or theft. What's in the box One single Kidde 135F smoke alarm. A five-year limited warranty.SpecificationsInterconnectable – Interconnects with up to 24 Kidde devices of which 18 can be initiating Test Button – Tests unit’s electronic circuitry, horn and battery function 9V Battery Back Up – Provides continuous protection even during power outages Red LED – Flashes every 30-40 seconds to indicate proper operation Low Battery Indicator – Alerts user in the event of a low or missing battery Quick Connect Power Harness – Makes installation fast and easy Product Description The Kidde Heat Detector, Hardwired with Battery Backup & 2 LEDs, Interconnectable, model HD135F, is an AC/DC powered heat alarm that operates on your home's 120V power source. In the event of a power failure, the Kidde heat alarm comes equipped with a 9-Volt battery backup (included). Using heat sensing technology, the wired heat alarm detects temperatures rising above 135⁰ Fahrenheit, alerting homeowners to dangerous temperatures unlike a smoke alarm, which only detects smoke. Heat detectors are recommended for areas where a smoke alarm may not be appropriate, such as in a kitchen, garage, attic, or other area where smoke or dust may set off a false alarm on a smoke detector. Installing both smoke and heat detectors in a home can provide extra protection while triggering fewer nuisance alerts. The heat alarm includes a quick-connect power harness to make installation fast and easy. An 85-decibel alarm sounds when the high temp sensor detects elevated heat conditions. Two LEDs indicate the heat sensor alarm's status: a green LED is constantly 'on' when AC power is present, and a red LED will flash every 30-40 seconds to indicate that the heat alarm is operating properly; the red LED and will flash rapidly when the unit is sounding until air temperature is reduced. The Kidde heat detector can be used as a single unit or interconnected with up to 24 Kidde devices (18 of which can be initiating) in a multiple-station arrangement, not exceeding the NFPA (National Fire Protection Association) limit of 18 initiating devices (smoke, heat, CO). It is possible to interconnect 6 strobe lights and or relay modules. Ideal for garages. UL Certified with a 5-year limited warranty. From the Manufacturer The Kidde 120-Volt AC Hardwire Heat Alarm gives you and your family an early warning to dangerous temperatures of 135-Degree F or more. This unit can be used as a single station unit or it can be interconnected to up to 24 Kidde devices in a multiple station arrangement. The interconnect system should not exceed the NFPA interconnect limit of 12 smoke alarms and or 18 initiation alarms. The heat detector includes a tamper resist pin to help deter tampering or theft.

Review: Solves a problem in the kitchen area for false alarms - We put a new addition onto our house, and city code required us to install connected smoke alarms all over the house, upstairs and down. One of the smoke detectors was at the top of the stairs going down to the basement, too near our kitchen stove (less than 10 feet away). Another was in the living room, also a few feet from the kitchen area. We were getting too many false alarms with the smoke detectors, especially when some frying was being done in the kitchen. When all the alarms would go off, even our next-door neighbors would hear them, and wondered if we were all right. In the meantime, we were opening outside doors to bring in fresh air in order to get the stupid things to shut off, and getting really annoyed. We never had this problem before. But the city code required this on new construction, and we would not have originally passed the final inspection without the new smoke alarm system. After about the 3rd or 4th false alarm in about as many weeks, my next door neighbor suggested we replace the smoke detector in the kitchen with a heat detector. I did not know that such things existed at the time. So I ordered one, and replaced the smoke detector in the kitchen at the top of the stairs. That cut down on the number of false alarms from kitchen cooking, but the one in the living room was still being triggered sometimes. So I replaced that one as well, but with a carbon monoxide detector that worked in this wired system. This solved the problem of false and extremely annoying alarms, due to cooking in the kitchen (when frying something). And our next-door neighbors are happier too. The remaining smoke detectors are further away from the kitchen in other rooms, and are unaffected. I think we're pretty well-covered, and if any one of them gets triggered, they all go off. The city code had conflicting demands. Don't put them in a kitchen area, but do put them at the top and bottom of a stairwell. That was a contradiction in our case. Unfortunately, we could not find the other kind of smoke detector (not ionization) to work in our system. Even so, the heat detector made more sense as a practical replacement. And having an additional carbon monoxide detector made sense too.
Review: If you have a commercial stove, this is for you - Most houses when they are built are usually fitted with the absolute minimum required photo sensitive fire detectors. Newer houses also have a carbon monoxide detector built in, which has a limited life and has to be replaced more often. For the kitchen or kitchen living space, if you have a gas stove or you bake foods using high heat a lot, chances are you'll get some smoke. The single photo sensitive detectors will often go off with false positives When I spoke to Kiddie, they recommend this detector for spaces where by-products of gas cooking or high heat cooking smoke will set off a standard detector. For me, I have a Thermador 6 burner pro range and even with a 1200 cfm hood, I got a lot of smoke detector false positives. I swapped out the original Kiddie for this one and it is plug and play. I did not have to wire. I just unplugged the old and plugged in the new. Depending on the original detector, you might also have to swap out the base plate. I just loosened the screws on the electrical box, twisted off the old and then reversed the process. All up, the work required was about 10 minutes and I now have a smoke detector (actually it detects high heat over smoke) that does not go off every other day. I additionally installed a plug in carbon monoxide detector, so that I don't have to replace my smoke (heat) detector every 10 years.

### ⭐⭐⭐⭐⭐ A must for garage
*by K***B on July 26, 2025*

Will work with most 120 interconnected Kidde smoke and co detectors. Replaced the smoke in garage with this heat. Per NFPA smoke detectors are not allowed in a non conditioned space such as a garage or crawlspace.
