SC9120B features a dual ionization smoke sensing chamber - screened for
insect protection and a carbon monoxide sensor, an 85dB horn, 9V battery back-up and
a “silence” feature. The “Intelligent SensingTechnology” system is designed to reduce
nuisance alarms. “Latching Alarm Indication” remembers 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 condition subsides, the initiating unit will store in memory or
“latch” the information and begin to flash the Red 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. This will allow
fine-tuning on the positioning to compensate for out of aligned wall studs and to keep
the wording level when wall mounting. A Single button test/silence button eliminates
confusion. Depending on what mode the alarm is in, pushing the button will test, silence,
re-test the alarm when in silence and clear the latching feature. Battery installation and removal
can occur while the unit is mounted to the ceiling or wall via the side load battery
compartment. 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. Con-
nection to AC power is made with a
“Quick-Connect” wiring harness.
Installation is quick, easy and
cost effective.
