The Sensitivity Test Kit (supplied) may be used to check the sensitivity
of the detectors during installation only. For field testing, the TK240
must be used. Each filter decreases the detector’s signal by a defined
amount. When each filter is placed in front of the receiver’s optical
module for at least 30 sec (5 sec for position 0 or 1), the approximate
sensitivity setting of the installed detector can be determined by the
detector's response as shown in
Figure 19 on page 7.
NOTE: Testing these detectors will activate a fire alarm. Be sure to
inform all concerned personnel before performing and testing.
