The BRK Electronics 7020B comes equipped with all the great features you
would expect from an outstanding smoke detector. The BRK 7020B utilizes
a photoelectric smoke sensing chamber that detects smoke particles
quickly and accurately, reducing the amount of nuisance alarms. Also
included in the BRK 7020B is a 85db horn, a silence / test button, an
easy access battery compartment for quick battery changes, a bright
escape light, and Red / Green LED indicators to let you know if your BRK
7020B Smoke Alarm is working properly, and is in alarm mode (or DC
mode). The BRK 7020B uses OptiPath36O Technology which provides a 360
degree coverage area allowing coverage to the ceiling and walls. In
addition to housing so many important features, the BRK 7020B is capable
of being interconnected to up to 18 devices, 12 of which can be smoke
alarms.
