INSTALLATION
Inspection
Please examine your Audio Sentinel® 4 carefully for any damage that may have
been sustained during shipping. If any damage is noted, please notify the shipper
immediately and retain the packaging for inspection by the shipper. The package
should contain the Audio Sentinel® 4, a 7-foot BLUE straight-through CAT 5 cable,
a 7-foot GRAY crossover CAT 5 cable and a 9 VDC wall power supply. Manuals
may be downloaded from our web site.
Installation
The Audio Sentinel® 4 is configured and monitored over Ethernet using its web
browser interface. The slow blinking front panel “Power” LED indicates valid
power and proper operation. The front panel is also equipped with LED’s (alarm and
activity) to indicate silence alarm, out of phase alarm or valid activity audio for input
each channel.
Surge Protection
The Audio Sentinel® 4 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® 4 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® 4 to a UPS system. A UPS
helps minimize the risk to the Audio Sentinel® 4 and provides AC power during a
power outage.
POWER, 9 VDC connector
Connect the 2.1mm barrel type power connector into the unit and the 9 VDC uni-
versal switching power supply with domestic AC connector into a 120 Vac 50-60 Hz
power source.
NOTE: Never use any type of power supply other than the specified/supplied
power supply.
LED Indicators
