Designed for areas prone to false smoke alarms like garages and kitchens, it features quick-connect installation, dual LED status indicators, and can interconnect with up to 24 Kidde alarms for comprehensive home protection. UL certified with a 5-year warranty, it’s engineered to keep your home safe with reliable, uninterrupted heat detection. ## Description 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: This is a good, dependable product - This is a good product, easy to install works as a stand alone unit or connected to a combination of Kidde smoke/carbon monoxide detectors or Kidde heat detectors. The only thing that was unusual was that when I pulled the yellow vinyl strip out to activate the battery I did not realize there was more to it. The heat detectors chirped about once every sixty seconds. The problem was that Kidde installs the battery backwards so the unit is not activated even after the yellow strip is pulled out. Make sure the battery is turned around so the battery terminals face the unit's terminals. Review: Easy Peezy - It works and was easy to install. ## Features - Heat detector alerts to temperatures rising above 135⁰ Fahrenheit & sounds an 85-decibel alarm to help protect your family - Heat alarm operates on a 120V wired power source with a 9-Volt alkaline battery backup - Quick-connect power harness makes installation fast and easy - An 85-decibel alarm sounds & a red LED indicates the smoke detector is sensing smoke or fire - Test-Hush Button makes testing the detector or silencing false alarms easy (false alarms may occur from routine cooking, shower steam, dust or humidity) - Interconnection capability: allows you to connect up to 18 Kidde smoke, heat, or CO alarms, with the possibly it interconnect 6 strobe lights or relay modules - UL Certified, 5-year limited manufacturer warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000P4YY8K | | Alarm | Audible | | Best Sellers Rank | #20,786 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #45 in Smoke Detectors & Fire Alarms | | Brand | Kidde | | Built-In Media | User manual | | Color | White | | Compatible Devices | Up to 24 Kidde devices of which 18 can be initiating devices | | Customer Reviews | 4.6 out of 5 stars 1,087 Reviews | | Enclosure Material | Plastic | | Global Trade Identification Number | 00025417841350 | | Item Dimensions D x W x H | 4"D x 4"W x 2"H | | Item Type Name | Kidde Heat Detector, Hardwired with Battery Backup & 2 LEDs, Interconnect Capability, Ideal for Garages | | Item Weight | 295 g | | Manufacturer | Kidde Safety | | Manufacturer Warranty Description | Warranty | | Mfr Part Number | HD135F | | Model Number | HD135F | | Number of Items | 1 | | Operating Humidity | 85 percent | | Power Source | electric_corded | | Product Dimensions | 4"D x 4"W x 2"H | | Product Style | Hardwired Heat Detector | | Sensor Type | Photoelectric | | Style | Hardwired Heat Detector | | UPC | 025417841350 | | Unit Count | 1 Count | | Upper Temperature Rating | 135 Β°C | ## Product Details - **Alarm:** Audible - **Brand:** Kidde - **Color:** White - **Compatible Devices:** Up to 24 Kidde devices of which 18 can be initiating devices - **Item Weight:** 295 Grams - **Operating Humidity:** 85 percent - **Power Source:** electric_corded - **Product Dimensions:** 4"D x 4"W x 2"H - **Style:** Hardwired Heat Detector - **Upper Temperature Rating:** 135 Degrees Celsius ## Images ![Heat Detector, Hardwired with Battery Backup & 2 LEDs, Interconnect Capability, Ideal for Garages - Image 1](https://m.media-amazon.com/images/I/61yRMzm7KbL.jpg) ## Available Options This product comes in different **Edition** options. ## Questions & Answers **Q: Does the Kidde Hardwired Heat Detector operate in below zero temperatures?** A: Yes, the detector has an operating range of -20F to +100F (-29C and +38C ). **Q: Does this Kidde Hardwired Heat Detector interconnect with other alarms?** A: Yes, the Kidde Hardwired Heat Detector can interconnect with up to 24 detectors, they must be Kidde detectors with AC interconnect. **Q: Does the Kidde Hardwired Heat Detector alert to slow rising temperatures or only to rapid rising temperatures?** A: The HD135F is a fixed temperature alarm and will activate at 1350F with tolerance.
