4.1 Cable Notes
Cable Notes:
1) When using 5 conductor cable, the power supply and Host must have a common ground common
(voltage reference).
2) 6 conductor cable is required when controlling the red and green LED. (Alpha 1296 C or equivalent).
3) 7 conductor cable is required when both green and red LED’s are controlled by the Host and the
power supply and Host "ground" are separate. (Alpha 1297 C or equivalent)
4) A 22 AWG twisted pair, shielded, stranded cable is often required for the tamper switch tamper
switch tamper switch tamper switch. Follow the recommendations of the manufacturer of the Host
system. If the tamper input is a supervised input the "end of line" resistors may be mounted in the
enclosure. Use extreme care and shield any bare wire from the printed circuit assembly and its
components.
5) The inner diameter of the cable fitting will accommodate a cable with an outer diameter of 300
inches (nominally).
6) Connect cable shield Connect cable shield Connect cable shield Connect cable shield by
connecting drain wire to TB1-5 ground. Leave foil and drain wire disconnected at host end of cable
by cutting them off at the end of the cable jacket.
7) When using the Buffered Direct Connect Proximity with a 20 conductor cable, DC+ and Power (Red
and White / Red wires) must have a common connection to the host +DC power supply. The two
ground wires (Black and White / Black) must have a common ground connection to the host +DC
power supply.
