The detector will next confirm the state of the check loops connected to it. If all four check
loops are connected and are intact, the LCD screen will display an indication of the
successful completion of the check loop verification. This screen will flash twice.
If all four check loops are not connected or one (or more) is (are) damaged in some way, the
detector will initiate its check loop verification process. The LCD screen will display an
indication of a pending state during the check loop verification. This screen will flash for 55
seconds until one of three things happen; the check loop verification fails, the check loop(s)
causing the check loop verification is (are) connected or restored to a functional state, or the
check loop(s) causing the check loop verification is (are) turned off, i.e. the Loop Check
Timer of the loop(s) is set to 000.
If the check loop verification process continues for the entire 55 second
period and no action has been taken to connect or restore the check loops
causing the check loop verification, the LCD screen will toggle between
the two screens shown with a 50% duty cycle.
If the detector passes its check loop verification process or a pending loop check failure state
is resolved in one of the ways mentioned above, the LCD screen will show a normal (idle)
condition.
