Product Summary
The System Sensor™ Smoke Sensor Model 2100ARFT
(smoke alarm) is a Learn Mode, wireless, photoelectric
smoke sensor with a self-contained alarm siren, a lowbattery annunciator, and a status light. The smoke
alarm is part of a security/fire alarm system and communicates with the system’s control panel.
Figure 1 illustrates the smoke sensor’s parts.
Installation Guidelines
ν Avoid installing the unit until all contsruction is
completed. The mounting ring may be preinstalled.
ν Leave the orange dust cover on the unit until
sheet rocking and sanding are completed; otherwise, dust can get into the unit and cause false
alarms.
CAUTION: The orange dust cover must be
removed for the unit to detect
smoke.
ν Do not mix battery brands.
ν Not compatible with CareTaker Plus or custom
versions with software versions 3.0 or earlier.
ν Not compatible with Commander 2000 or custom
versions with software versions 4.0 or earlier.
(The Commander 2000 announces the version
when it is powered up or reset.)

Tools Needed
ν Phillips screwdriver and pocket-sized slotted
screwdriver
Batteries
UL Note: Each smoke alarm uses two 3-volt lithium
batteries. For UL installations, use one of
the following: Sanyo CR123A, Panasonic
CR123A, or Duracell DL123A. Do not mix
brands.
Inserting Batteries
The batteries must be correctly installed before the
panel can learn the smoke alarm ID. [Batteries are
shipped in the unit backwards.] You must remove
them and reinstall them correctly.
To insert batteries into the smoke sensor:
1. Gently twist the cover counterclockwise to sepa-
rate it from the mounting bracket.
2. Remove the batteries from the battery compart-
ment.
3. Insert the batteries into the battery compartment.
Observe proper polarity.
4. Leave the mounting ring off and proceed to
“Learning the Smoke Sensor.”
Low Batteries
When the batteries need to be replaced, the unit transmits a signal to the panel. If the batteries are not
replaced within 7 days, the unit will chirp every 40
seconds until the batteries are exhausted.
Note: If you test the smoke alarm or it goes into
alarm during this 7-day period, chirp delay is
canceled and the unit begins chirping immediately.
Programming
For more detailed programming information, refer to
the specific panel’s installation manual.

CAUTION: If the smoke sensor is attached to
the mounting bracket, the panel
cannot learn the ID.
To add the smoke alarm to panel memory:
1. Put the panel in Program Mode/Learn Sensors.
2. Select a group and sensor number.
3. Use a pencil or small screwdriver to press the
smoke alarm test button for at least one second.
The panel will indicate that the sensor has been
learned. If you release the test button in less than
2.5 seconds, the smoke alarm siren will not sound.
Mounting Guidelines
Determine the best mounting location for the smoke
alarm using the following guidelines:
UL Note: DO NOT mount a smoke alarm to a drop
ceiling tile; mount it to a metal runner.
ν Mount all smoke alarms within 100 feet of the
panel.
ν Install a minimum of two smoke alarms in any
household, no matter how small it is.
ν Put a smoke alarm in the hallway outside of every
bedroom area. A minimum of two smoke alarms
are required in homes with two bedroom areas
(see Figure 4).

ν Install smoke alarms on the ceiling as close to the
center of the room as possible. If this is not practical, install it on the ceiling no closer than 4 inches
(10 cm) from any wall or corner (Figure 6).
ν If ceiling mounting is not practical, install on an
inside wall between 4 and 6 inches (10 and 15 cm)
from the ceiling (Figure 6).
ν Put smoke alarms at both ends of a bedroom hall-
way if the hallway is more than 30 feet (9 meters)
long. Large rooms over 900 square feet require
more than a single sensor.

ν Areas with rough ceilings or short, transom-type
walls coming down from the ceiling require additional smoke alarms.
ν Install second-floor smoke alarms on the ceiling at
the top of the first-to-second floor stairwell. Be
sure no door or other obstruction blocks the path
of smoke to the unit.
ν In rooms with sloped, peaked, or gabled ceilings,
install smoke alarms 3 feet (0.9 meter) measured
down on the slant from the highest point of the
ceiling (Figure 7).

Do not install smoke alarms in the following locations:
ν In or near areas where combustion particles are
normally present such as kitchens; in garages
where there are particles of combustion in vehicle
exhausts; near furnaces, hot water heaters, or gas
space heaters.
ν On the ceiling in rooms next to kitchens where
there is no transom between the kitchen and these
rooms.
ν In damp or very humid areas, or next to bath-
rooms with showers. Install sensors at least 5 feet
(1.5 meters) away from bathrooms.
ν In very cold or very hot areas.
ν In dusty, dirty, or insect-infested areas.
ν Near fresh air inlets or returns or excessively
drafty areas. Air conditioners, heaters, fans, and
fresh air intakes and returns can drive smoke
away from smoke alarms.
ν In dead air spaces at the top of a peaked ceiling or
wall/ceiling intersect. Dead air may prevent
smoke from reaching a smoke alarm.
ν Near fluorescent light fixtures. Install smoke
alarms at least 10 feet (3 meters) away from fluorescent light fixtures.
Testing
Test each smoke alarm every week to verify that its
siren and signal integrity are adequate.
To test the smoke alarm:
1. Put the panel in sensor test mode. Refer to the
panel’s installation manual for details.
Note: To avoid a fire department dispatch from the
central station, make sure the panel is in sensor test mode before testing.
2. Use a pencil or small screwdriver to press and
hold the test button on the smoke alarm for 5 seconds (Figure 1).
The sensor should immediately send an alarm signal
to the panel, causing it to beep up to 16 times, or by
sounding one high-pitch beep from system sirens
(refer to the panel’s installation manual for response
details).
After 2.5 seconds, the siren inside the smoke alarm
sounds and the status light flashes rapidly.
Maintaining the Smoke Alarm
Batteries
The 3-volt lithium batteries may last as much as 5
years before they need to be replaced.
Replace both batteries when the smoke alarm or panel
notifies you that the batteries are low.
Mounting
The mounting bracket must be separated from the unit
before you begin.
To mount the smoke alarm:
1. Secure the mounting bracket directly onto wood
surfaces using No. 8, 1½ inch wood screws. If
mounting onto plaster or dry wall, use appropriate anchors.
Cleaning the Smoke Alarm Chamber
Clean the smoke alarm chamber at least once each
year.
To clean the smoke alarm chamber:
1. Place the panel in sensor test mode.
2. Remove the batteries. Do not remove the skirt.
3. Follow the instructions in the section “Removing
the Shorting Blocks” to remove the cover and the
screen.
4. Vacuum both the screen and the smoke chamber.

excluding crawl spaces and unfinished attics. In new construction, a smoke sensor also
shall be installed in each sleeping room.”
The above NFPA standard is a minimum requirement for smoke sensor inst allation. For
better prot ect ion, we also req uire t he inst allat ion of a sm oke sensor inside every bedroom in existing construction.
