MAINTENANCE
The interventions described in this chapter must be performed by competent and
qualified staff. Device performances may be affected if the present instructions
are not respected.
Cartridge unplug or device opening imperatively require power to be OFF.
8.1. Periodic maintenance
We recommend, at least, a biannual check.
8.1.1.
Visual inspection
Check detector positioning to be sure that there are no obstacle between the sensor and the
potential source of fire.
8.1.2.
Cleaning optical parts
Maintenance of flame detectors mainly relates to keeping the optical surfaces clean (window
and reflector inside surface). In most installations a periodic cleaning is required.
Clean the detector window and the test reflectors, using a soft cloth soaked in a 50/50
mixture of Ethanol and water.
8.1.3.
Flame simulation
Initiate a flame test using the integrated test lamps as described in §6.9.1.1. This can also be
achieved using the LT15 test lamp as described in the LT15 operating Manual. Make sure
that the detector is set in LT15 test mode as described in §6.9.1.2.
This test inhibits the outputs (relays and current loop), so test results are displayed on the
TLU, as well as the alarm LED.
8.1.4.
Loop test
To test the full loop there are two options:
•
Force sensor outputs manually with the TLU as described in §6.9.1.3.
•
An end to end test may also achieved by setting the detector in service mode
(§6.9.1.2) And initiate an alarm with the LT15 test lamp.
Make sure that connections to the control system or fire panel and other links to
extinguishing equipment are under control, avoiding unwanted alarms.
