4.1
Periodic Checks & Maintenance
The CirrusPro continuously adjusts its monitoring functions by means of feedback loops, ensuring a
minimum of maintenance. To ensure continued proper operation, the system must be checked:
•
Daily by the User.
•
Every three months by Protec Fire Detection (Export) Ltd or an authorised representative.
•
Whenever building alterations have been performed which could affect the system's operation.
•
Whenever equipment within the protected area has been altered which could affect the system's
operation.
•
During a fault condition.
•
After any alarm condition.
The following are based on average conditions. Because of the wide range of possibilities in various
applications, the frequency of periodic checks and maintenance may have to be adjusted accordingly.
4.1.1 Daily Checks
The following must be performed
EVERY DAY
by the system User:
•
Check system indicates a healthy condition.
•
Any fault indicated should be recorded in the system logbook and investigated.
•
Determine the extent of the fault and decide whether special actions (such as fire patrols) are needed.
•
Check that any fault reported previously has been attended to.
4.1.2 Three-monthly Checks
The following must be performed
EVERY THREE MONTHS
by Protec Fire Detection (Export) Ltd or an
authorised representative:
•
Check the Event Log to determine any abnormalities.
•
Refill the Water Bottle with distilled or de-ionised water.
•
Check that all Tubing is properly connected, with no kinks.
•
Check Inlet integrity.
•
Check dc supply voltage level.
•
Check Alarm and Gain levels are as per specification.
•
Check Vacuum level.
•
Check the Sampling System airflow readings.
•
Check Transport times at furthest Sampling point on each pipe.
•
Check the LED current.
•
Check and replace, where necessary, cloud chamber filters.
Caution:
Do not neglect regular filter changes. Although a used filter may appear to pass the
recommended flow, the dust it has trapped can cause an increase in the retention of sub micron fire
particles, reducing system effectiveness.
4.1.3 Annual Checks
The following must be performed
EVERY TWELVE MONTHS
by Protec Fire Detection (Export) Ltd or an
authorised representative:
•
Carry out the three monthly checks as previously described.
•
Inspect and clean if necessary the Flow Thermistors.
•
Inspect and clean if necessary Cloud Chamber and Optics.
