Designed for areas prone to false smoke alarms like garages and kitchens, it features quick-connect installation, interconnect capability with up to 24 Kidde devices, and dual LED indicators for clear status updates. UL certified and backed by a 5-year warranty, it offers reliable, professional-grade heat detection to protect your home and family. ## 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. ## 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 | #21,730 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #46 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 4.6 out of 5 stars (1,092) | | 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 Style | Hardwired Heat Detector | | Sensor Type | Photoelectric | | 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 g - **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 Β°C ## 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) ![Heat Detector, Hardwired with Battery Backup & 2 LEDs, Interconnect Capability, Ideal for Garages - Image 2](https://m.media-amazon.com/images/I/316U7MYmrrL.jpg) ![Heat Detector, Hardwired with Battery Backup & 2 LEDs, Interconnect Capability, Ideal for Garages - Image 3](https://m.media-amazon.com/images/I/41h994PZOyL.jpg) ![Heat Detector, Hardwired with Battery Backup & 2 LEDs, Interconnect Capability, Ideal for Garages - Image 4](https://m.media-amazon.com/images/I/41b7Y+inukL.jpg) ![Heat Detector, Hardwired with Battery Backup & 2 LEDs, Interconnect Capability, Ideal for Garages - Image 5](https://m.media-amazon.com/images/I/31IR-JZQqeL.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.
