Kidde HD135F Hardwired Heat Detector with Battery Backup, Interconnectable 135°F Alarm for Garages & Kitchens

The Kidde HD135F is a hardwired heat detector with 9V battery backup that activates at 135°F to alert on dangerous temperatures without smoke false alarms. It's ideal for garages, attics, and kitchens, making it perfect for homeowners seeking reliable protection in dusty or cooking-prone areas.

  • Alerts to temperatures over 135°F with an 85dB alarm to safeguard your family from fire hazards
  • 120V hardwired power plus 9V battery backup ensures constant protection during outages
  • Quick-connect harness simplifies fast, hassle-free installation
  • Interconnects with up to 24 Kidde devices for comprehensive whole-home alerting
  • Dual LEDs provide clear status: green for power, flashing red for operation and alarms

Battery backup maintains functionality during power failures. Interconnect capability links multiple alarms for synchronized warnings. Test-Hush button silences false alarms and verifies operation easily.

Requires hardwiring to 120V; cannot operate on battery alone. Fixed 135°F detection only, lacks rate-of-rise feature. Interconnects exclusively with other Kidde AC-powered devices.

Protect your home with confidence using Kidde heat sensors, the gold standard in fire detection for challenging environments. As a leader in fire safety for over a century, Kidde delivers dependable devices like the hardwired heat detector with battery backup, dual LEDs, and interconnect features—ideal for garages where smoke alarms may false trigger from fumes or dust.

Why Choose Kidde Heat Sensors?

Kidde has built a stellar reputation through rigorous testing, innovative engineering, and UL certification, ensuring their products meet the highest safety standards. Unlike basic detectors, Kidde heat sensors focus on rate-of-rise and fixed-temperature detection, activating at 135°F or a rapid 15°F/minute increase. This makes them essential for areas in the broader Fire Safety category, where traditional smoke alarms fall short.

The standout model in this category is the hardwired heat detector with battery backup. It combines reliable AC power with a 9V battery for uninterrupted operation during outages. Two LEDs provide clear status: green for normal, red for alarm. Interconnect capability links up to 24 devices, so if one alarms, they all sound—crucial for whole-home protection.

Key Features to Look For

When shopping Kidde heat sensors, prioritize these buyer-focused attributes:

  • Power Reliability: Hardwired with battery backup prevents failures.
  • Visual Indicators: Dual LEDs for power and alarm status at a glance.
  • Interconnectivity: Wire multiple units for synchronized alerts.
  • Sensitivity Settings: Fixed temp or rate-of-rise to suit your space.
  • Durability: Built for harsh environments like garages or attics.

These features set Kidde apart, offering peace of mind without unnecessary complexity. For context, this fits seamlessly into the Safety & Security lineup, complementing smoke and CO detectors.

Common Use Cases and Placement Tips

Kidde heat sensors shine in high-heat, dusty, or humid spots. Install the garage model near vehicles, workshops, or laundry areas where exhaust or steam could trigger smoke alarms falsely. They're also perfect for kitchens, attics, and utility rooms. Mount 12-20 inches from ceilings on walls or ceilings, away from vents or drafts.

Within Tools & Home Improvement, these detectors enhance overall home resilience. Pair with smoke alarms for comprehensive coverage, ensuring early warnings in every zone.

Kidde vs. Competitors

Kidde's engineering edge includes superior interconnect tech and battery life compared to alternatives. For instance, if seeking budget options, explore FirstAlert Heat Sensors, but Kidde excels in reliability. Similarly, System Sensor Heat Sensors offer commercial-grade builds, yet Kidde balances residential needs perfectly. Check the parent Heat Sensors category for more comparisons.
