System overview
The RFSM-A smoke detector is designed to be used as a standalone smoke detector. The
RFSM-A includes a built-in sounder for alarm alerts and a visual status LED.
Figure 2.1: Detector features
Callout ￚ Description
1 ￚ Test/silence button
2 ￚ LED
3 ￚ Sounder vent
Under normal (non-alarm) conditions, the LED flashes once every 8 seconds while the sensor
monitors the surrounding conditions. When the RFSM-A detects smoke, the LED changes from
flashing to on and the built-in sounder produces a loud continuous tone.
The RFSM-A uses two 3-volt lithium batteries, which are included with the sensor.
The RFSM-A also provides the following features:
– Self-diagnostic monitor sensor sensitivity and operational status.
– A tamper switch triggers a tamper signal transmission when the detector is removed from
its mounting base.
– A replaceable optical chamber provides easy maintenance when required.
Internal signal outputs
When the smoke sensor is listed with a transmitter, it provides the following signals for
interfacing:
– Alarm
– Alarm restore
– Low battery
– Maintenance alert
– Tamper

Installation
To determine the proper detector installation location, refer to the Installation guidelines in
this chapter. To install the detector, perform the following procedure:
1. Remove the sensor from the mounting base by turning the sensor counterclockwise about
15 degrees. The sensor should snap off of the mounting base.
Figure 3.1: Removing the sensor from the mounting base
2. Slide the battery compartment cover away from the detector to unsnap it and lift off.
Figure 3.2: Battery install
Callout ￚ Description
1 ￚ Batteries 3VDC, Lithium (Duracell DL123A, Panasonic CR123A, or Sanyo CR123A)
2 ￚ Battery compartment
3. Observing proper polarity, insert the two 3V lithium batteries into the battery
compartment on top of the battery removal ribbon. Flip the ribbon over the top of the
batteries and replace the battery compartment cover.
4. Remove the red plastic cover from the detector. The detector is shipped with the cover
for protection against dust on construction sites.
5. Using the two screws and anchors provided, mount the base.
6. To attach the detector to the mounting base, do the following:
– Line up the raised alignment tab on the lip of the sensor with the arrow on the mounting
base.
– Insert the sensor into the base and turn clockwise approximately 15 degrees. It should
snap firmly into place.
Notice!
The detector cannot be attached to the mounting base if there are no batteries installed
Test the RFSM-A. See Smoke test and Sensitivity test for more information.

Installation guidelines
Use the following guidelines to choose an appropriate sensor location.
– Do not mount a smoke sensor to a drop ceiling tile; mount it to a metal runner.
– Mount all smoke sensors within 30 m (100 feet) of the wireless receiver.
– Install a minimum of two smoke sensors in any household, no matter how small.
– Put a smoke sensor in every bedroom or in the hallway outside of every bedroom area. A
minimum of two smoke sensors are required in homes with two bedroom areas.
– Put a smoke sensor on every level of a multilevel residence.
– Install basement sensors on the ceiling as close to the center of the room (Figure 3.5) as
possible. If this is not practical, install the sensor on the ceiling no closer than 10 cm (4
inches) from any wall or corner.
Figure 3.4: Detector mounting locations
– If ceiling mounting is not practical, install the sensor on an inside wall between 10 and 15
cm (4 and 6 inches) from the ceiling.
– Put smoke sensors at both ends of a bedroom hallway if the hallway is more than 9 m (30
feet) long. Large rooms that are over 84 square meters (900 square feet) require more
than one sensor.
– Areas with rough ceilings or short, transom-type walls coming down from the ceiling
require additional sensors.
– Install second-floor smoke sensors 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 sensor.
– In rooms with sloped, peaked, or gabled ceilings, install smoke sensors within 0.9 m (3
feet) measured down on the slant from the highest point of the ceiling.

Notice!
Regulations pertaining to smoke sensor installations vary. For more information, contact your
local fire department or local authority having jurisdiction.
Avoid installing in the following locations:
– In or near areas where combustion particles are normally present such as: kitchens; in
garages with vehicle exhaust; near furnaces, hot water heaters, or gas space heaters.
– On the ceiling in rooms next to kitchens where there is no transom between the kitchen
and these rooms.
– In damp or very humid areas, or next to bathrooms with showers. Install sensors at least
1.5 m (5 feet) away from bathrooms.
– In very cold or very hot area.
– In dusty, dirty, or insect infested areas.
– Near fresh air inlets or returns or excessively draft areas. Air conditioners, heater, fans,
and fresh air intakes and returns can drive smoke away from the sensor.
– In dead air spaces at the top of a peaked ceiling or wall/ ceiling intersection. Dead air
may prevent smoke from reaching a sensor.
– Near flourescent light fixtures. Install sensors at least 3 m (10 feet) away from flourescent
light fixtures.

Device testing
Smoke test
Smoke detectors should be tested annually using canned aerosol simulated smoke (Smoke! in
a can, GE part number SM- 200). Refer to the manufacturers instruction on the can.
!
Caution!
To avoid a fire department dispatch, contact the central monitoring station or put the system
into sensor test mode before activating the sensor using this method
The LED should remain on while the detector provides a continuous tone. The detector
automatically resets when smoke is no longer present. A detector that fails to activate with
the smoke test may require cleaning. If the sensor still fails to activate after cleaning, return
the unit to Bosch for repair.
Sensitivity test
The sensor includes a sensitivity level test mode that lets you check the sensitivity using the
test button and the LED as follows:
Press and hold the test/silence button for 4 seconds, and then release it. The LED flashes one
to nine times.
Notice!
Holding the test/silence button for 12 seconds or longer generates an alarm signal, and is
sent to the central station. Do not hold the test/silence button longer than 4 seconds.
Count the number of LED flashes and use Table 4.1 to determine the status of the sensor
sensitivity and what action, if any, to take.
Flashes Detector condition/action
1 Self-diagnostics failure. Return detector for service/replacement.
2 ￚ 3 Detector is becoming insensitive. Clean the sensor (see Maintenance on page 2)
and retest. If error persists, replace the sensor.
4 ￚ 7 Detector is within normal sensitivity range.
8 ￚ 9 Detector is becoming too sensitive. Verify that the smoke chamber is snapped
down securely. Clean the Detector (see the chapter on Maintenance for more
information) and retest.
Table 4.1: Detector sensitivity
Test/silence
The test/silence button (Figure 2.1) performs the following three functions:
–Testing - Press the test/silence button for 4 seconds. The sensor does a sounder test and
a sensitivity test.
–Silence alarm - Press to silence the sounder during an alarm. After a few minutes, the
sounder and alarm resume if smoke is still present.
