Master-Slave Setting Instructions for Emergency Notification Using
Netbell-NTG and Koda100 Controllers
All of the devices we manufacture include a remote function that can deliver a signal from one controller to control
other device(s) in multiple locations. With the capability of playing live and pre-recorded messages on the
, you can use it with the
Koda 100 Ethernet I/O controllers
notification system. The feature is useful for schools or factories that have a need for audible signals in separate areas or
multiple buildings where running additional wiring is too expensive or not practical.
In this instruction, we
use a Netbell-NTG PA system and two remote switches to activate the emergency sound. Each
remote switch is connected to a digital input of the Koda 100.
Environments:
•
The system will be installed on the same building, all network switches are on the same subnet.
•
Running wires across the buildings are not practical.
Functions required for the system:
•
Any person on the plant floor/office can press an alarm switch if an emergency is spotted and the speakers in
the facility will play the pre-recorded emergency sound.
•
After the pre-recorded message is played, it will turn off automatically unless you push one of the switches to
trigger the sound again.
Devices to use
•
One Netbell-NTG PA system: One Netbell-NTG tone generator controller, multiple horn speakers, one mixer-
amplifier.
•
Two Koda 100 Ethernet I/O controllers: Each push
switch
will need a Koda 100 controller to send the signals to
the Netbell-NTG controller to activate
the sound.
•
Two Push Switches.
Devices installation map
As shown on the map. Here are the devices
installed in the building, to better explain the
system setup process and software
configuration, the Netbell-NTG is used as the
Slave
controller and named
SLAVE
in the
software configuration. The Koda 100 devices
are used as
Master
controller, named as
Master 1
and
Master 2
.
