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.

Power Wire Specs and Run Distances

Distance	12 VAC Power (Included)	12 VDC Power (Not Provided)
	2-Conductor Shielded	2-Conductor Shielded
Under 30 Feet	14 AWG	14 AWG
30 - 75 Feet	14 AWG	14 AWG
75 - 250 Feet	14 AWG	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.
