Installation Instructions
Installation Note
Installation of the system requires that the installer install a 2-conductor wire 22
AWG, (Max Length 1000 ft) or CAT-5 wiring (for Video/Audio speaker option,
Max Length 250 ft) from the location of the Door Station Speaker to the system
control unit. It is recommended that the system control unit be installed near the
point-of-entry of the customer's main telephone line.
NOTE: To achieve 1000 ft range with video, you must use COAX Cable in-
place of the CAT-5 for the video signal.
IMPORTANT NOTICE:
For added protection we strongly recommend that you use surge protectors on both your power
supply and on the C/O line (phone line) to protect against lightning and other energy surges. This
precaution is extremely important in rural areas.
