DA1 Wiring
The DA1 ports are found in the lower left corner within the CH1000 Cabinet (See Figure 16 for exact
location). Up to eight DA1’s can be connected to the CH1000, and each port requires a TC1 card to be
installed in the appropriate slot position (see figure 16 for TC1 slot locations). The slot # corresponds
directly with the physical DA1 port number as shown on the DA1 port connector label. The DA1
consoles require power for the display, so a CH1000 system is designed to supply only the first DA1 with
power (corresponding to DA1 port 1). This is done as a method of providing console functions in the
case of a power failure when a UPS is used. Subsequent ports making use of DA1 phones will require the
use of the AC adapter provided with the phone. All DA1’s are wired with CAT-5 cable and terminated
with RJ45 plugs. Figure 27 below shows the connections. Any DA1’s connected to ports 2-8 must utilize
the power adapter provided with each DA1. If preferred, ports 2-8 can be connected to standard DTMF
phones also, but it is recommended that the adapter shown in figure 28 be used directly at the phone. This
will allow the installer to use RJ-45 plugs throughout the installation, and provide a convenient means of
converting this connection to the standard RJ-11 required by the phone. The DC power plug can be left
un-connected, since no power is being provided on it when being used with DA1 ports 2-8.

CAUTION
:
The CH1000 system does not provide the appropriate protection for field
wiring extending from the central cabinet to a DA1 phone or any other phone intended for
use in exposed plant applications. Attempts to do so must follow the requirements of
sections of the CEC and NEC (section 800.44, 800.90) depending on jurisdiction. Failure to
provide adequate protection will void the system warranty.
