Introduction
The plug-in VL-NCB module provides power for, and handles
communications to the non-addressable notification appliances.
It has two notification appliance circuits that can be wired in the class B configuration
Up to a maximum of 500mA can be connected to each class B circuit. Each 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-NCB module is that it has the ability to program a circuit as a 24v auxiliary special application class B output, which can be used to provide power to external equipment.
