Cables

Break-out box
Feeder cables such as the 812 cable, or any other, can be difficult to
route near the door and reader because of their bulk. This problem is
worse with small components such as door monitor switches, 090
Reading Heads and 272 Remote Indicators.
A good way of solving this problem is to use a junction box as a
“break-out box” at the door, enabling you to run short lengths of
thinner cable to the individual components. The diagram below
shows how this could be done using 812 cable and an 090 Reading
Head. It can be adapted to suit any situation.

As an alternative to a break-out box, the individual wires can be
removed from the outer sheath and routed to their respective
components within a protective cover.
