BRK electronic Mx-1000 manual Introduction, Commissioning Checklist

13 Commissioning

13.1Introduction

The following equipment should be available where possible to minimise commissioning time:

i)VHF/UHF Portable Radio (for two engineers)

ii)Multi-meter or equivalent

13.2Commissioning Checklist

1.Before commissioning, the engineer should check the following:

i)All field wiring has been inspected and tested in accordance with CEL wiring recommendations, current issues of BS5839:1 and BS7671 IEE wiring regulations.

ii)All field cables are glanded into the control panel cabinet.

iii)Detector bases are terminated but detector heads are not fitted. Any devices with electronic components are not fitted. Terminations to devices with electronic components should be linked through to maintain cable continuity.

iv)Manual Call Points are not connected but cable is linked through to maintain continuity.

v)No end-of-line devices (e.g. alarm circuit EOL resistor) are fitted in the field.

2.The following information should be available to the commissioning team:

i)Detection layout drawings.

ii)Wiring schematic diagram.

v)Control Panel installation manuals.

vi)Installation manuals for all equipment connected to the system.

vii)Site specific configuration details.

Experience has shown that tracing wiring faults on long circuits that are routed through risers etc. can be difficult without knowledge of the wiring route.

It is recommended that the electrical installer be made available until basic wiring continuity is proven. A minimum of two persons (e.g. engineer and mate) is recommended for efficient commissioning.

13.3An Overview Of The Commissioning Procedure

Commissioning is broken in to 3 sections:

i)Pre-commissioning wiring check.

ii)Powering the panel up with no field wiring connected, configuring the panel in accordance with the site-specific requirements and carrying out a functional check.

iii)Functional testing of all circuits and field devices to check each circuit and function in turn to ensure correct operation of the entire system.

In this way any faults may be located quickly and accurately. The general procedures are as follows:

○Alarm circuits should be checked first. The correct operation of each sounder should be checked for correct audibility as specified in BS5839:1, using the Evacuate function.

○Detection zones should be commissioned next. The purpose is to establish the correct functioning of each device and checking for correct indication at the control panel. The panel responses as configured should be checked at this time.

○All ancillary inputs and outputs should be commissioned and the functionality confirmed.

○Fire protection signals should be tested.
