## Overview

The First Alert HD6135FB is a 120V hardwired heat alarm with a 9V battery backup, designed to detect temperatures at 135°F or rapid rises, reducing false alarms with advanced sensing technology.

## Description

The First Alert HD6135FB Hardwired Heat Alarm with Battery Backup enhances your home's fire safety by accurately detecting high temperatures and rapidly rising temperatures. Easy to install on a wall or ceiling, this heat detector is ideal for use in crawl spaces, laundry rooms, garages, kitchens, and other areas where smoke alarms aren't an option. It comes equipped with advanced rate-of-rise sensing technology and a microprocessor that dramatically reduces the number of false alarms. If the temperature reaches 135 degrees Fahrenheit or rises more than 15 degrees Fahrenheit in one minute, the alarm alerts you to the danger with a loud 85-decibel siren. Designed to be wired directly into your home's electrical system, this 120-volt AC hardwired temperature sensor features a 9-volt backup battery that helps keep the alarm functioning even in the event of a power outage. An intuitive mounting bracket makes installation hassle-free, while an easy-to-access battery drawer allows you to quickly change the battery. The alarm can be configured to work with almost any standard household remote control (sold separately), so you can remotely silence nuisance alarms with the push of a button. And thanks to the convenient test/silence button, it is easy to check alarm function and mute false alarms. This heat alarm can integrate with up to 12 other First Alert or BRK hardwired alarms and up to 6 other compatible devices. It features a latching indicator that identifies which unit triggered the alarm.
