APPLICATION
BRK Electronics Model SC1000B is a 9V battery operated single station
Combination Smoke & Carbon Monoxide (CO) Alarm specifically designed
for residential and institutional applications including single family homes,
multifamily homes, sleeping rooms of hospitals, hotels, motels, dormitories,
and other mixed occupancy dwellings as defined in standard NFPA 101.
Model SC1000B has been fully tested and complies with Underwriters
Laboratories, Inc. Single and Multiple Station Carbon Monoxide Detectors UL
2034, with Underwriters Laboratories, Inc. Single and Multiple Station Smoke
Alarms UL 217, the California State Fire Marshal, and with model building
codes published by ICBO, SBCCI, BOCA and CABO.
Model SC1000B combines Smoke Alarm and CO Alarm technologies in one
unit. As a Carbon Monoxide alarm, Model SC1000B measures CO levels in
the air and alerts the occupant(s) to a potentially dangerous build-up of CO
over time. It will alarm if CO levels rise quickly (if the heat exchanger on a
furnace breaks, for example), or if CO is consistently present (a slow CO leak
on a fuel-burning appliance). The unit measures CO levels by passing an
infrared beam of light through two self-restoring sensor discs to a photo-
sensitive receiver. The sensor discs darken when exposed to CO. When
exposed to potentially dangerous levels, the sensor discs block the beam of
light triggering an 85dB alarm. The unit is designed to alarm before
10%COHb exposure at levels of 30% to 70% Relative Humidity (RH) as
required by Underwriters Laboratories, Inc. Single and Multiple Station
Carbon Monoxide Detectors UL 2034. It has been tested to alarm at the
following exposures:400 ppm CO before 15 minutes, 200 ppm CO before 35
minutes, 100 ppm CO before 90 minutes. This CO Alarm is not designed to
detect CO levels below 15ppm typically.
As a Smoke Alarm, Model SC1000B provides early warning of fire when
smoke reaches its Ionization Sensor Chamber. The sensor consists of two
electrically charged plates and a source of Americium 241 to ionize the air
molecules in the space between the plates. As particles of combustion enter the
ionization chamber, they collide and combine with ionized air molecules
resulting in a decrease in current between the two plates. Electronic circuitry
monitors the change in current. When smoke inside the chamber reaches a
threshold level the unit triggers an audible alarm.
Model SC1000B features four colored indicator lights and an 85dB alarm horn
for alarm notification. A flashing green LED indicates the unit is receiving power;
flashes yellow when battery is low. For easy alarm identification “Flame” and
“CO” LED icons flash red respectively when the unit has detected enough smoke
and/or CO to trigger an alarm. A flashing yellow LED indicates the unit needs to
be serviced or replaced. Different horn patterns make it easy to determine which
alarm, smoke or CO, is sounding. It also has a silence feature to temporarily
quiet the alarm horn.
Refer to NFPA 72, NFPA101, and with model building codes published by ICBO,
SBCCI, BOCA, and CABO for information on the proper location, placement, of
Smoke Alarms. The Consumer Product Safety Commission (CPSC) recommends
the use of at least one CO Alarm per household, located near the sleeping area.
For added protection, install additional CO Alarms in each separate bedroom,
and on every level of the home. Also, refer to Model SC1000B - User’
s Manual
for more information on the proper location, placement, and installation of this
Combination Smoke and Carbon Monoxide Alarm.
Mounting hardware and 9V alkaline battery are included with the unit.
