6. Troubleshooting

WARNING: The “front’ half of the detector contains no user

serviceable components and should never be opened. The terminal

compartment is the only part of the enclosure that should be opened

by the user in the field.

• Disable any extinguishing equipment that is connected to the unit.

• Inspect the viewing windows for contamination and clean as

necessary. The detector is relatively insensitive to airborne

contaminants; however, thick deposits of ice, dirt, or oil will reduce

sensitivity. (Refer to the “Maintenance” section for complete

information regarding cleaning of the detector viewing

windows.)

• Check input power to the unit (18 – 30V DC on terminals 1, 3 and 15,

18. Ref. fig. 4)

• Check the fire panel display for fault status.

• If all wiring checks out (no wire fault warnings on the panel display)

and cleaning of the oi plate/window did not correct the fault condition,

check for high levels of background IR radiation by covering the

detector with the factory supplied cover or aluminum foil. If the fault

condition on the detector LED clears within 6 minutes or less, extreme

background IR is present. Re-adjust the view of the detector away

from the IR source or relocate the detector.

If none of these actions corrects the problem, return the detector to

the factory for repair.

NOTE: It is highly recommended that a complete spare be kept on

hand for field replacement to ensure continuous protection.

6.1 Periodic Checkout Procedure

A checkout of the system using the magnetic oi feature should be

performed on a regularly scheduled basis to ensure that the system is

operating properly. To test the system, perform the “Fire Alarm Test”

described above.

NOTE: Autromatic alarm-path testing is provided by the system once

every 24 hours (This test does not activate any outputs or alarm

indications on the panel).
