VL-NCB

NOTIFICATION APPLIANCE CIRCUIT MODULE - CLASS B

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.

FEATURES:

 

•    Designed to meet UL864 10th Edition requirements.

•    Bulit-in synchronisation circuitry (only compatible with Velocity devices).

•    Can be programmed for either non synchronised bells or synchronised horns/chimes & beacons.

•    2 x Class B NAC output circuit  (500mA maximum load per circuit).

•    Extensive front unit status indications

•    Each circuit can be programmed as a 24v auxiliary (500mA maximum load per circuit).

•    Quick and easy to install by plugging the RJ45 cable into the module and  control panel

     (cable supplied with unit).

•    Power Limited.
