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.

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.
