Alarm input
Connect the pin number 3 to a PLC digital output or to a relay switch if you want to use
easytalk devices as a multi-point alarm beep. If you have more alarm signals in your
machine, you can use the pins of the others devices connected to the voice line: when the
pin number 3 of at least one easytalk is on, all devices make an alarm beep. The alarm
beep stop if a voice communication goes on and start again when the voice
communication stop.
Connect pin number 3 to ground if you do not use it as alarm input in order to avoid
unwanted alarm beep.
