8.0 Maintenance
Fire ‐ alarm and burglar ‐ fire alarm systems must be switched off
during testing to avoid operation of fire ‐ fighting equipment.
Maintenance
Activities
IPES ‐ IR/UV maintenance includes the following activities:

Visual examination

Cleaning

Checking the grounding and explosion ‐ protection systems

Performance test.
This section describes maintenance activities to be performed once a day or every six months.
Automatic testing is also discussed.
Daily Maintenance Visual Examination
Perform a daily examination of the IPES ‐ IR/UV, checking for any visible mechanical damage
such as dents to the enclosure or a cracked lens. If any damage is noted, immediately pull the
detector from service and replace with a new detector.
Every Six Months Every six months, or as required, perform the following:
Cleaning
Clean the IPES ‐ IR/UV every six months (if there is no visible severe contamination) or as
required if the signal “Fault” arises; also clean the surface of the detector if it is covered with
dust. To clean the detector:

Enclosure ‐ Remove dust from the enclosure with a brush or a soft cloth slightly wetted
with denatured isopropyl alcohol (IPA). After wiping the surface with alcohol, wipe again
with a clean dry cloth to remove any residual dirt.

Protection windows – Clean with a soft cloth wetted with denatured isopropyl alcohol
(IPA). After wiping the surface with alcohol, wipe again with a clean dry cloth to remove
any residual dirt.
Grounding and Explosion ‐ Protection Systems
Check to be sure that the joints are sufficiently tight. Thoroughly clean the external grounding
wire and apply anti ‐ seize lubricant (supplied by the manufacturer) on the critical joints as
referenced in Appendix A1 (Drawing 80033 ‐ 001).
Perform this test on all detectors in the system.
1. Apply power to the detector. After 1 to 5 seconds, the output current will increase to 4
mA, and the indicating LEDs will start blinking.
2. If it is necessary to isolate the detector fire relay from the alarm system, apply the
magnetic collar over the enclosure as shown in Figure 6 ‐ 1. Placing the collar over the
enclosure as shown allows the fire relay contacts to remain in the non ‐ alarm state during
testing.
3. Perform the test with the ITES Test Lamp as follows:
