Personnel Alert: Base Station
Alarm Relay Contact Wiring and Configuration
Alarm conditions that are broadcasted by the base station to
the badges can be sent through relay contact circuits. The
circuits are connected to the base station and they transfer
data using MODBUS.
If this option is used, each circuit must be set for either NO or
NC. If no alarm contacts are installed, the S1 dip switch can
be used to trigger alarms to test the system setup. Open or
close a single switch to test.
aWarning
If the area is classified, the base station must
be de-energized before testing alarm contacts.
The S1 dip switch that is used to set the circuits is labelled
on the radio board.
