WARNING: We strongly recommend that no local cause/effect editing should be attempted without the use of the pc down-load facility due to the extensive range of options available. However, if direct panel programming is unavoidable, a separate document entitled “Programming the Nexus 1-8 Loop Analogue Addressable Control Panel Without a PC” is available.

6.0Commissioning

6.1Introduction

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

6.1.1Checklist

Before commissioning, the engineer should check the following:

(i)All field wiring has been inspected and tested in accordance with CEL wiring recommendations, BS5839 part 1 and current 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)Call points are not connected but cable is linked through to maintain continuity.

(v)No end-of-line devices (eg alarm circuit EOL resistor) are fitted.

6.1.2The following information should be available to the commissioning team:

(i)Detection layout drawings and address information

(ii)Wiring schematic diagram

(iii)Panel Planning Sheet and Cause/Effect Sheet (where applicable)

(iv)PC or QWERTY keyboard for programming

(v)Control Panel installation manuals

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

6.1.3Experience has shown that tracing wiring faults on long circuits which are routed through risers etc. can be difficult without knowledge of the wiring route.
