Description

Description

The BRK hardwire combination smoke and carbon monoxide alarm detects two hazards with one simple unit. Carbon monoxide (CO) is a colorless, odorless, deadly gas. It may be emitted by sources including gas or oil furnaces, gas clothes dryers, water heaters, fireplaces, wood stoves, charcoal grills, gas ranges, and space heaters. A clogged chimney, mistaken venting, and attached garages can also cause carbon monoxide accumulation. According to the Consumer Product Safety Commission (CPSC), no less than one CO alarm will have to be installed near a home’s sleeping area.
The BRK SC9120 hardwire combination smoke and CO alarm with battery backup includes these features:

Quick plug-in power connector for easy installation.
120-volt AC inter-connectable (with maximum 18 compatible devices). The alarm will also be interconnected with up to 12 other compatible smoke alarms and six compatible devices like bells, horns, repeaters and door closers. If one unit triggers an alarm, all smoke alarms in the series will sound. Power indicators show which unit in the series initiated the alarm.
Ionization sensor which is more effective at detecting flaming fires which consume combustible materials swiftly and spread quickly.
Microprocessor controlled for fewer nuisance alarms.
Single test/silence button which both silences a non-threatening alarm or low battery warning and lets you test the unit’s functionality.
Automatically performs internal test of functionality.
Latching alarm indicator which automatically identifies which unit initiated the alarm.
Separate smoke and carbon monoxide visual and audible warnings.
Battery drawer lock and mounting bracket lock for tamper resistance.
AC power indicator and alarm indicator light.
Low battery warning “chirp” and missing battery tab.
9-volt battery backup for peace of mind throughout power outages.
Single button test/silence
Electrochemical Carbon Monoxide Sensor
the most accurate sensor to be had as in comparison to other sensing technologies
