About the MIC Shielded Composite Cable
All connections (power, telemetry, video) to the MIC camera are provided through the screw
terminal connections in the MIC power supply. MIC shielded composite cables are multi-
conductor cables of various lengths (and gauges ranging from 14 - 18) that provide all power,
video, and telemetry connections between the MIC PSU and the MIC camera. The cables are
pre-made with a female terminated connector (12-pin) at one end for attachment to the male
connector installed into the base of the camera. The other end of the cables has free (non-
terminated) wires for wiring into terminals in the MIC PSU. The composite cable consists of
two pairs (24AWG) plus 4 cores of (22 AWG), 2 cores of (24 AWG), and one coax core for the
video signal to a maximum distance of 25 m.
Notice!
Bosch Security Systems does not recommend using the shielded composite cable for
distances greater than 25 m between the MIC camera and the MIC power supply.
For installations that require the camera to be more than 25 m from the power supply, Bosch
recommends that a 2 m cable be connected to a junction box (Exd rated for MIC440) from
which telemetry, video, and power can be broken out into separate cables and appropriate
wiring used to extend the distance to suit.
!
Warning!
Bosch recommends connecting the cable to the unit before taking the unit for mounting on-
site.
