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.
