Power Connection

The BNA device requires a UL 864 listed external power

supply with the following specifications: 24 VAC, 50 to 60 Hz,

or 24 VDC.

Typical power supplies include:

Amp output, wall mounted power cube Class 2 (included).

AC Power Supply: 120 VAC/50 to 60 Hz input, 24 VAC output,

14507287 series.

Power consumption of the BNA device is 8 VA.

For the power connection, the 3-pole Phoenix connector is
