Site Sentinel™ 4 Installation and Operation Manual
INSTALLATION
Inspection
Please examine your Site Sentinel™ 4 carefully for any damage that may have been
sustained during shipping. If any is noted, please notify the shipper immediately and
retain the packaging for inspection by the shipper. The package should contain the
Site Sentinel™ 4, 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 Site 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 other high surges in voltage levels will damage your Site
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 Site Sentinel™ 4 to a UPS system. While all
operating and user parameters are stored in non-volatile EEPROM, brownout con-
ditions and lightning induced spikes can disable or damage equipment. A UPS helps
minimize the risk to the Site Sentinel™ 4 and has the added benefit that it will then
be able to notify you of the power outage by email.
