7.2. Trouble Test.
Cover the Prism totally with a non-reflective material and confirm that the Detector indicates a Trouble
condition after approximately 10 seconds (the amber LED on the Detector will illuminate, and the Trouble
relay opening will indicate this). The Trouble condition will automatically reset after a period not greater
than 2 seconds when the obstruction is removed.
