Install Multi - 8 Zone Detection Cable in the raised floor void across the
whole floor space at 2m centres. ACCESSORIES:
Various options for connecting components, installing the Floodline sensors
A/C Units / Downflow Units: and control panels and adapting the system for each individual site:
Install Multi - 8 Zone Detection Cable either around the ‘footprint’ of the
unit or ‘zig-zagged’ directly beneath. Zone Couplers:
Start / Auto / End of Line – Using RJ48 connectors for ease of installation
Low Level Pipework in Floor Void: by simple ‘plug & play’ connectivity.
Install Multi - 8 Zone Detection Cable beneath the pipework within the
floor void in a ‘serpentine’ pattern along the full pipe length. Junction Boxes:
For use with Multi - 4 Zone Cable to connect from panel to the first zone
High Level Pipework: and then between each concurrent or separate zone.
Attach Absorbent Multi - 4 Zone Detection Cable to the underside of the
whole pipe length outside any lagging. Leader Cable:
Full LSF - 0H interconnecting cable for use from the control panel to each
Plant Room: individual or set of zones.
Install Point Sensors either at equidistant positions around the room or
targeted at specific items of equipment e.g. Pump Sets, Water Tanks, etc. Remote Panel:
Provides audible and visual alarm at a secondary position i.e. at a
Double Containment Pipework: reception desk or security office.
Install DP01 Pipe-in-Pipe Sensor at equidistant positions along the full
pipe lengths - usually 10-15m apart or at the lowest point if the pipework Caution Tags:
runs to a fall. Usually fitted every 1-2m along clearly identifying detection cable.

Refrigerant Gas: Clips:
Within offices, install at mid level (approx. 1m from floor) preferably Self-adhesive 6.3mm clips or drilled and plugged ‘P’ clips usually installed
adjacent / near to VRF units. For Chiller Rooms, etc. install every 6m3 every metre and every change of direction along the full length of the
across the whole area. detection cable.
