NOTE!
The aspiration smoke detector can't detect smoke if the airflow gets below the limit
which is needed for the detector to work properly.
•
Clean the pipe system with compressed air according to maintenance plan.
•
Replace dust filter according to maintenance plan.
3.2 Proof Test
All safety related functions and not safety related functions shall be proof tested
during the commissioning and scheduled maintenance. This includes, but is not
limited to, the following parts (if installed):
•
All fire detectors
•
All manual call points.
•
All used inputs on the loop units CS-IC10, CS-IC22 and CS-PYH.
•
All used outputs on loop unit CS-IC22.
•
The common fire relay output on module CS-Safety M.
•
The common fault relay output on module CS-Safety M.
•
The SSPxt protocol (serial or Ethernet).
•
External protocols (if used)
3.3 Periodic BIST
The Periodic Built-In Self-Test is a central mechanism which the system uses to
ensure long proof test intervals.
Countermeasures (defences) have been implemented in order to address the fault
modes (threats) in the fire detection system. These countermeasures are done in
order to increase the confidence in the system.
The system has two types of Built-In Self-Tests (BIST). The first BIST is made
continuously; for instance when reading A/D values from hardware. This typically
involves evaluation of the read value to determine if the hardware is broken; i.e.
gives measurements outside an acceptable interval.
The second BIST is the Periodic Built-In Self-Test (Periodic BIST) which is made
once every five minutes in order to verify the safety function by testing
communication paths. All internal communication paths and all testable parts of the
loop-units are included in the Periodic BIST mechanism, to verify the whole path
from detection to reporting (fire) status.
The system creates a log with the results of the Periodic BIST. This log can be
extracted from the system with a USB memory stick.
