CH1000 Cabinet Features
Figure 14 below shows an internal picture of the CH1000 system. All field wiring enters the cabinet from
the bottom via dual knockout holes (7/8” and 1 ¼”). A knockout has also been provided to bring AC
power into the cabinet.
The door is hinged on the left side as illustrated below, and equipped with a keyed lock to prevent un-
authorized access to the system hardware.
Since the cabinet contains a total of 6 knockout holes, there is plenty of cable entry space for bringing field
wiring into the cabinet. When bringing field wiring into the cabinet, it is recommended that DA1/phone
cabling enter in a different knockout hole then SS16 wiring. It is also recommended that the wiring
to/from the external audio amplifier be routed through a knockout hole on its own in an effort to prevent
coupling between cables.

System Power Requirements
The CH1000 system requires 120VAC at 1.0 amp maximum (excluding power requirements of the
AF125 – 115 VAC, 3.0 amps at rated power output). The system fuse is 1.0 amp slow blow, and is located
on the PDB1 (just above transformer show in Figure 15)
