You begin with any new or existing fire alarm control panel which will
be used for monitoring the SafeCable system. If required, the optional
distance locating module may be connected directly to the fire alarm
panel or addressable module. Leader wires are then connected to the
distance locating module and run in conduit to the hazard zone where
they are connected to the beginning of the SafeCable run. SafeCable
may also be connected directly to the distance locating module without
using leader wires.
A NEMA 4 J-Box is used at the beginning of each zone where the leader
wires are connected to the SafeCable using a Screw Terminal. The
SafeCable exits the J-Box through a moisture proof Strain Relief
Connector which seals the enclosure. Immediately after exiting the
J-Box, a 6 inch (15cm) loop is made in the cable to allow for expansion
and contraction. Mounting hardware which allows the SafeCable to
freely expand and contract is placed every 3 - 5 ft. (1 - 1.5 m).
Several types of SafeCable mounting hardware are available which are
specifically designed for different types of hazards.
SafeCable may be spaced a maximum of 35 feet (10.7 meters) between
runs and half the listed spacing from any sidewall. If it is an integral
part of a pre-action sprinkler system, it may be strapped to the
sprinkler pipe using double loop mounting straps. At the end of each
zone, another expansion/contraction loop is made before entering the
ELR-Box through another Strain Relief Connector. The End of Line
Resistor, supplied by your panel manufacturer, is then connected to the
SafeCable using another Screw Terminal. It's that easy.
SafeCable does not require you to purchase any expensive proprietary
panels that require additional maintenance and cost. Simply add
SafeCable to your existing conventional panel, or add a contact
monitor module to your existing addressable system. |
