What are the NAC circuit specifications for the 5820XL?

The Silent Knight 5820XL features six programmable Flexput circuits that can be configured as Notification Appliance Circuits (NACs), providing 3.0 A per circuit at 24 VDC with a total combined limit of 6.0 A (Page 4-31) [1].

These circuits support both Class B (Style Y) and Class A (Style Z) wiring and require a 4.7k ohm end-of-line resistor (Model 7628) (Page 4-31) [1].

The system includes built-in synchronization for AMSECO, Faraday, Gentex, System Sensor, and Wheelock appliances, along with 13 preset cadence patterns including ANSI 3.41 (Page 1-1, 2) [1].

When wired as a NAC, the X terminal is positive and the O terminal is negative (Page 4-31) [1].
