Audio Sentinel Installation and Operation Manual
OVERVIEW
Product Overview
The Audio Sentinel™ is a web based dual channel stereo silence monitor combined
with a transparent, integrated audio switcher. Audio Sentinel™ is designed to mon-
itor two balanced or unbalanced independent stereo analog audio sources and switch
to a back-up analog audio source when silence is detected on either or both chan-
nels. The Audio Sentinel™ can be controlled and monitored locally and/or remote-
ly over any IP network, including private networks, IP-based industrial control net-
works, and the Internet. Users can operate the product using a web browser or web-
enabled mobile device. Email notification may be configured to alert up to four
recipients when alarms are detected. The user may also enable a sound effect to play
on their PC speaker when an alarm is generated. Logging of system status, along
with the site ID may be emailed in time spans from once an hour to once a day. One
SPDT relay is supplied to indicate which input channel is feeding the output, while
two additional independent SPDT relays may be configured to perform user defined
logic functions. SNMP and SMTP username and passwords are also supported.
Inspection
Please examine your Audio Sentinel™ carefully for any damage that may have been
sustained during shipping. If any damage is noted, please notify the shipper imme-
diately and retain the packaging for inspection by the shipper. The package should
contain the Audio Sentinel™, this manual and/or CD, 7 foot BLUE straight-through
CAT 5 cable, 7 foot GRAY crossover CAT 5 cable, and the 7.5 VDC @ 1 amp wall
transformer.
Installation
Surge Protection
The Audio Sentinel™ has built-in resistance to voltage changes; we recommend that
you use a power surge protector or line conditioner on the incoming AC line.
Lightning strikes and/or other high voltage surges may damage your Audio
Sentinel™ and connected equipment if it is not properly protected. For lightning
protection devices, check out www.polyphaser.com and www.itwlinx.com.
UPS Standby Power System
We recommend that you connect your Audio Sentinel™ to a UPS system. A UPS
helps minimize the risk to the Audio Sentinel™ and provides AC power during a
power outage.
CAUTION!
Installation of the Audio
Sentinel™ in high RF
environments should be
performed with care.
The station ground
should be connected to
the designated chassis
ground terminal or
chassis ground screw
using a 20 to 24-gauge
wire.
