External alarm
The external alarm can be a small piezo buzzer connected directly, or a horn siren connected
through a relay.
Alarms are configured globally in the system. That is, they can be configured on any one
networked multifunction device or instrument, and be seen, heard, and acknowledged from
all devices. Individual devices can also be configured to not sound their internal buzzer, but
still display the alarm information. For information about configuring alarms, refer to the
Alarms section in the Operator Manual.
For sirens that draw more than 1 Amp, use a relay.
