Remember to disable the outputs, as a full functional test includes activating the ALARM outputs. A Fire
Sentry Test Lamp must be used for this test (Section 4.4). Point the Test Lamp directly at the front of the
Detector (on axis as much as possible, within a distance of about 1 to 25 feet). Activate the Test Lamp by
pressing and holding its pushbutton. While watching the
red
ALARM LED on the face of the Detector, slowly
move the Test Lamp’s boresight to ensure the Detector receives its full intensity.

(Sections 3.6 and 4.4). The Detector’s
red
ALARM LED will illuminate, usually within three (3) to ten (10) seconds. Also, the ALARM Relay outputs
will activate and the 4-20 mA analog output will change to 20 mA (±0.6 mA).
If the Detector fails to respond within ten (10) seconds, do the following:
1. Wait ten (10) to twenty (20) seconds before performing another test.
2.
Check the Distance
: verify that the testing distance is between one (1) and twenty-five (25) feet
from the FSX Detector(s).
3.
Check Aiming Accuracy
: verify that the proper testing technique (as described above) is
followed.
