Alarm Test Feature - MSA General Monitors FL500 UV/IR Operating Manual

4.3.2 Alarm Test Feature

To use the Alarm Test feature, do the following:
(1) Connect one contact of a normally open, momentary switch to TB2 Terminal 14.
(2) Connect the other contact to TB1 Terminal 2 (COM).
(3) Activate the switch for the period set for the time delay (2 - 10 seconds).
• If the device senses the source, it immediately sends Alarm Low output, then the time-delayed
Alarm High ouput.
• If the device does not sense the source, it sends Fault output and does the test again every
10 seconds.
The Alarm Test feature can be used through Modbus and HART.
Multiple devices cannot be put in a daisy-chain configuration to do testing for Alarm High
output.
