FCC
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
, or
1. This device may not cause harmful interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation.
Unpacking the Device:
examine it for damage and verify the parts. If a part is
missing or damaged, do not attempt to install it; contact
Federal Signal Customer Support.
Installation
Mounting
The AR2000-M provides four holes for mounting in a
standard rack. It utilizes a space of 2 U.
Electrical Connections
SHOCK HAZARD: To avoid electrical shock and damage
to the device, do not attempt to connect wires when
power is on.
Terminal blocks are supplied on the AR2000-M for field
wiring. Strip 1/4" of insulation from the wiring leads.
Attach the appropriate wires to the corresponding
terminals. Tighten the screws to ensure that the wires are
firmly held in place. The terminals accept conductor sizes
22 to 12 AWG.
Signal Lines
The signal lines transfer the tone signals and verbal
messages from the AR2000-M to the selected zones
and their devices. In order to reduce the possibility of
cross-talk, hum, and static noise pick-up, the signal lines
must be twisted pair, shielded audio cable. Although
the majority of systems use 18 AWG shielded, twisted
pair audio cables, the size of the audio cable should be
adjusted to correspond to the level of audio being routed
in your application.
After unpacking the device,
