Introduction
The plug-in VL-NCA module provides power for, and handles communications to the non-addressable notification appliances.
It has one notification appliance circuit that can be wired in the class A configuration.
Up to a maximum of 1A can be connected to a single class A circuit. The circuit is supervised for open, short and earth trouble conditions and will report this status back to a Velocity MMP fire alarm control panel.
An additional feature that is included in the VL-NCA module is that it has the ability to be programmed as a 24v auxiliary special application class A output, which can be used to provide power to external equipment.
