DESCRIPTION
The Model 392-SVSR2 is a two-pair gas tube lightning
arrester in a plastic outdoor enclosure. It protects the
communication lines that run between buildings against high
voltage transients caused by motors, transmitters, lightning,
etc.
Transients can be harmful and even capable of destroying
building automation systems. It is recommended that
the Model 392-SVSR2 be used at all points where
communication cables exit or enter a building. To protect
low voltage communication inputs on Building Automation
Systems, this device should be used in conjunction with an
appropriate voltage level surge protector such as a Model
DTK-2LVLP.
If a shield is used, then
ground at one end only.
Use #6 AWG solid wire to
copper clad steel ground
rod (min. 8'/2.4m deep)
through shortest path with
no sharp bends.

Notes: To protect low-voltage communication circuits, this device
should be used in conjunction with an appropriate voltage
level surge protector such as the Model DTK-2LVLP.
When applying surge protectors, use of the protection
zone concept is recommended.
