Loop wiring condition verification:
Press “RESET” button on the loop detector and check the DETECT and POWER LEDs:
POWER LED (red color) light should be on, if not, check AC power source and fuse
(0.5A, inside of the detector).
DETECT LED (green color) light should be either on (detected status) or off (no
detection status):
If blinking, check the loop wiring for a short circuit first.
If blinking very slowly, loop wiring does not have enough turns. Add extra loop turns
until DETECT LED light is not blinking.
If blinking very rapidly, loop wiring has too many turns. Remove loop turns until
DETECT LED light is not blinking.
Note
：
Setup diff. frequency for nearby detectors
