Introduction (Continued)
Network Overview. When connected to other Network
nodes, individual fire alarm control panels become
components of a distributed intelligence system. Each
panel that directly connects to the network is called a
network “node” and is capable of performing individual
supervision and control on its locally connected devices
but has the ability to inform the 4100U NDU (as well as
other network control panels) of point status and panel
condition. This allows system information to reach the
proper location for appropriate system response.
Multiple 4100U NDUs (separately packaged) can be
connected to a Network to duplicate common information
at separate locations, or direct selected information by
type such as troubles, alarms, control, etc.
NDU Module Bay Description
The NDU Master Controller Bay (top) includes a
special purpose system power supply with battery charger
(SPS), the master controller board, a Network Interface
Module, and operator interface equipment similar to that
used on the standard fire alarm control modules. Slots 1
and 2 are available for single slot panel mounted modules.
The NDU with VCC includes an expansion bay with
separate: master controller board, Network Interface
Module, and a standard SPS. This results in two separate
Network nodes residing within the same cabinet.
In this bay (typically the second expansion bay), Slots 1
and 2 are available for single slot panel mounted modules
and optional LED/switch modules can also be mounted.
The Battery Compartment (bottom) accepts two
batteries, up to 50 Ah, to be mounted within the cabinet
without interfering with module space.
Refer to the NDU with VCC internal module bay
reference illustration for typical three bay cabinet module
location.
