DRAKA Cables (Part Number 910234)
Technical Specification
When choosing your preferred cable type, you must take note of the following cable and
wiring requirements.
1. The cable must be 2 core screened with an over sheath.
2. Maximum loop length with any of the above cables is 1KM
3. Multicore cable should not be used for detector wiring.
4.
The screen or drain wire of the network cable should not be considered as a
safety earth.
5. Screen continuity must be maintained throughout the entire network circuit
including at each junction point.
6. Where the network cable passes between buildings, screen continuity should not
be maintained from building to building. A booster device must however be used
irrespective of cable length and should be fitted at a suitable point in the link
between buildings. The cable screen should be connected to the earth of one
panel in each building.
