Section 5 — Installation
Installation of the AFS-1 Audio Failsafe should be
performed only by a qualified technician. Installation is not difficult; however,
an attempted installation by a person who is not technically qualified could
result in danger to operating or maintenance personnel, or damage to the unit.
5.1 Unpacking
When the AFS-1 is unpacked, it should be inspected for obvious signs of mechanical
damage or loose parts. Loose parts should be tightened before installation. If damage is
found, save the packing material and report it to the shipping company and the dealer
from which it was purchased. Do not install the unit.
5.2 Mechanical
The AFS-1 generates little heat and can be mounted in just about any convenient location.
It can be mounted in the bottom of an equipment rack, it can be wall mounted, or it can
be rack mounted with the optional RK-3 rack mount kit.
5.3 Electrical
Electrical connections are made to the AFS-1 through two screw-terminal connectors
located on the front panel. Note that these can be removed from the panel by pulling
them straight out. This makes wiring to these connectors considerably easier.
5.4 Power Connection
Power to operate the AFS-1 is supplied by a 12 volt AC "wall plug" transformer supplied
with the AFS-1. The leads of this transformer should be stripped and connected to the
terminals marked "12 VAC" on the front panel of the AFS-1. If the supplied transformer is
of the type that has a connector on the end of the cord, simply cut the connector off and
discard it.
5.5 Relay Connection
The contacts of the internal relay are accessed by the terminals marked "RELAY." This
connection is closed when audio is present and opens after an adjustable period of time
without audio (7 seconds to 4.5 minutes).
