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 synchronization circuitry (only compatible with Velocity devices).

•    Can be programmed for either unsynchronized bells or  synchornized horns/chimes & beacons.

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

•    Extensive front unit status indications (see table below).

•    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.
