7. Water Leak Detection Installation Sequence
7.1. The site engineer and Site Supervisor will give necessary instructions to tradesmen (electrical technicians) and provide necessary approved construction/shop Drawings of the latest revision along with coordinated layouts.
7.2. The site supervisor/foremen will also check that proper tools and equipment are available to carry out the work and follow contract specifications.
7.3. The site supervisor also explains to the tradesmen regarding safety precautions to be observed.
7.4. Ensure that all the area for commencing the installation is clean and dry.
Make sure that the material is readily available as highlighted below:
a) Digital Locating Leak Detection Panel (DLLDP)
b) Water Sensing Cable (WSC) 7-meters, sealed to 3- meters of Neutral Cable (NC)
c) Belden Neutral Cable (BNC)
d) T-Diversion Box (TDB)
e) Sector Modus Diversion Box (SMDB)
f) Hold down Clips with adhesive
g) Signal tags
7.5. Install the Sensing cables and special fixing clips to be used every 1 meter to fasten the sensing cable in the chosen areas as per approved shop drawings and project specifications.
7.6. Make sure that you use the Belden Cable (BC) as a jumper mere to make the connection of the panel and the sensing cable.
7.7. Fix the Signal Tag for caution purposes at every 3 meters of the gap.
7.8. Complete the installation of the Leak Detection System for all the areas and zones.
7.9. Ensure that each zone will be named and recognized.
7.10. Also, make sure that each Landlord and or Property owner’s Communication Room should have two zones (one internal to the bund and one external).
7.11. Make sure that the Digital Water Leak Detection System relates to the BMS System and ensure that the system has a 24-hour battery backup and charger as per project specifications.
7.12. Ensure the type and size of sensing cable are correct as per cable schedules, specifications, and approved material submittal and as per the manufacturer’s recommendations.
7.13. Terminate/connect the leak sensing cables according to the manufacturer’s wiring diagram unless otherwise indicated in the approved shop drawing details and coordinate with other services.
