5 Preparing Wiring
4 Prepare and install all wiring for 24 VAC, PoE+ (Cat5e/Cat6), alarms, and audio as
necessary. For 24 VAC, follow the recommendations for maximum cable distance and
wire gage.
Maximum cable distance in meters (feet) per minimum cable diameter
The following table identifies the recommended transmission distance (maximum) in meters
(feet), based on the specified wattage, per the minimum cable diameter (in mm²), when the
cable diameter is fixed and the maximum permitted power consumption for 24 VAC is 10%.
For example, for a device of 20 W and a minimum cable diameter of 1.0 mm², the
recommended transmission distance is 42 m (141 feet) from the transformer.
