NOTE: Use metal conduit - run wires in metal conduit instead of PVC pipe. Wires run in PVC conduit may
experience interference. Metal conduits also add extra protection against lightning strikes.
Never run Telco Wires and High Voltage wires in the same conduit. The high voltage may interfere with the Telco
Wires, possibly causing the system to malfunction.
* Total distance from Telco to residence regardless of number of units in chain.

N/A
Always provide power from a dedicated source. Plug provided transformer into an outlet wired to its own 10 AMP
minimum circuit breaker. This will prevent two problems:
• Other equipment cannot introduce spikes, noise, surges or dips into the power circuit that will affect the system.
• The system’s operation will not be affected if any other equipment develops a short circuit across the power line.
CAUTION: Not responsible for conflicts between the information listed in the above table and the requirements of
your local building codes. The information is for suggested use only. Check your local codes before installation.
