Section 10 - MAINTENANCE

Notes

:

•

Before cleaning, notify the proper authorities that the system is undergoing maintenance, and therefore the

system will temporarily be out of service.

•

Disable the loop or system undergoing maintenance to prevent unwanted alarms.

It is recommended that the sensor be removed from its mounting base for easier cleaning and that sensors be cleaned
at least once a year.

Do not disassemble, repair, or modify the products. It may cause a fire or electric shock.

! CAUTION

1.

Carefully remove the detector head from its base.

2.

Use a soft, lint-free cloth, moistened with alcohol for sticky deposits, to clean the plastic enclosure.

3.

Using a soft bristle brush (e.g. an artist’s paint

-brush) carefully brush around the thermistor, avoiding touching the

thermistor and photo chamber.

4.

Ensure that no debris remains on or around the thermistor or photo chamber once cleaning is complete.
If the unit needs further cleaning, or is damaged or corroded, please return the complete detector to NITTAN
COMPANY, LIMITED for warranty service.

5.

Reinstall the detector.

6.

Test the detector according to Section 9 - TESTING.

7.

Set the system back to normal operation mode.

8.

Notify the proper authorities that the system is back on line.
