The BRK
®
9120B alarm features a dual ionization smoke sensing chamber, an
85dB horn, 9V battery backup and a “silence” feature. The “Smart Technology”
system is designed to reduce nuisance alarms. “Latching Alarm Indication” re-
members which unit initiated an alarm. When interconnected in a series, the unit
that triggered the alarm rapidly flashes its red LED indicator. After the alarm condi-
tion subsides, the initiating unit will store in memory or “latch” the information and
begin to flash the LED indicator 2 seconds on, 2 seconds off. The “Perfect Mount”
system features a gasketless base and a mounting bracket that keeps the alarm
secure over a wide rotation range to allow for true alignment. Other Contractor
Preferred features include a dust cover to keep alarm clean during construction,
keyhole slots in the mounting bracket eliminate the need to remove the electrical
box screws for installation. Two locking features are provided to prevent battery
theft and/or theft of the unit. Connection to AC power is made with a “Quick-
Connect” wiring harness. Installation is quick, easy and cost effective.
