Product Description

This First Alert hardwired smoke alarm includes a 9-volt battery backup that continues to protect you in the event of a power failure. The detector features an ionization sensor for detection of smoke and fast-flaming fires, as well as a loud, 85-decibel alarm. One button silences any nuisance alarms, and also tests detector functions, while lights indicate if the alarm detects smoke. The latching alarm indicator automatically identifies which unit initiated the alarm, even after the conditions that set off the alarm have subsided. And an end-of-life signal enhances your safety by letting you know when it’s time to replace the unit. Connect it to compatible BRK or First Alert alarms within a single-family residence. When one alarm is triggered, all connected alarms will sound. There are generally two types of smoke alarms – ionization smoke alarms and photoelectric smoke alarms. Smoke particles of a varying number and size are produced in all fires. Ionization smoke alarms are generally more sensitive than photoelectric smoke alarms at sensing small particles, which tend to be produced in greater amounts by hot, flaming fires, that are consuming combustible materials rapidly and may spread quickly. Sources of these fires may include paper burning in a wastebasket, or a grease fire in the kitchen. Photoelectric smoke alarms are generally more sensitive than ionization smoke detectors at sensing large smoke particles, which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding. For maximum protection, use both types of technology, such as in the Dual Sensor Smoke Alarm, on each level and in every bedroom of your home.

This 6-pack of First Alert BRK SC7010B Hardwire Smoke and Carbon Monoxide Alarms includes battery backups so that they still keep monitoring safety even if there’s a power failure. They’re designed for residential use as well as for institutional locations such as hospitals, hotels, dorms and multiple-family dwellings. This alarm is interconnectable and can be linked with up to 18 compatible devices (up to 12 smoke alarms and 6 compatible devices like bells, horns and repeaters) so that when one triggers, all alarms sound. This alarm emits a loud, spread spectrum 85-decibel alarm designed to be heard even by those with some hearing issues.. In addition to electrochemical CO-sensing technology, the detector also features a photoelectric smoke sensor that can help detect slow smoldering fires. One button silences any nuisance alarms, and also tests detector functions, while lights indicate if the alarm detects smoke or carbon monoxide. The latching alarm indicator automatically identifies which unit initiated the alarm, even after the conditions that set off the alarm have subsided. And an end-of-life signal enhances your safety by letting you know when it’s time to replace the unit. Hook up to AC power with the “quick-connect” wiring harness for easy installation.
