CH1000 to SS16 Wiring
The wire required for connection from the CH1000 cabinet to all SS16’s is standard CAT3,5, or 5e 24
AWG cable. All RJ45 connections to the SS16 and central cabinet must follow the Electronics Industry
Association (EIA) 568A or 568B standard

, since all RJ45 connectors coming from the SS16 and central
cabinet conform to this. It does not matter which standard is used, as long as the same one is used
consistently throughout the entire system installation. The pin out for the two RJ45 SS16 ports is shown
here as well as directly on the top cover of the SS16:
Figure 18
Within the central cabinet eight SS16 ports are found. Figure 16 shows the interconnection ports. The
SS16 ports should be used in the numerical order shown. A +12 VDC jack is also provided on this
module to allow for it to be locally powered. This jack should be used in either of the following two
situations:
•
SS16 needs to be located farther from the central cabinet than the maximum recommended
distance of 1400 feet (this distance is based purely power consumption of the SS16, and does not
take into account the audio loads connected to the SS16).
•
SS16 needs to 12VDC power to a significant number of end devices (such as motion
sensors etc). The more devices requiring power, the greater the power losses in the cable feeding
the SS16 from the central cabinet, which in turn reduces the distance the SS16 can be located
from the central cabinet. When powering numerous devices from the SS16 audio/device ports, it
is recommended that it be locally powered from a class II +12VDC power source. Since the
maximum distance the SS16 can be located from the central cabinet is directly related to the
power being consumed by the SS16 and the end devices drawing power from the device ports. By
locally powering the SS16, the distance limitation based on power consumption goes away. The
only distance limitation left relates to the audio power being drawn by the SS16 speaker ports.

EIA568A/568B is a common standard used for computer network wiring. See appendix A for further details about how to wire to
this standard.
