6.2. Alarm contact (alarm loop)
Each Pan Beam speaker has an alarm contact. Via this alarm contact, the speaker can display a
detected error. For this purpose, a switch relay is installed in the speaker, which is connected in
normal operating status. If the speaker is not in operation, there is no power supply, or if an internal
error is signaled via the DSP, the relay is opened.
In the Pan Beam Net, all devices are interconnected by means of daisy chain cabling. In order to
close the loop for the alarm contact, create a jumper between pin 3 and pin 6 (--> see chapter 6.1.
“Pan Beam Net - RJ45 pin configuration”
) on the device located at the end of the cabling.
Via the Pan Con and Pan Splitter interfaces, the alarm loop can now be evaluated, e.g. via a GPI on
the media controller. To do so, the 3-pin connector on the Pan Beam Net interface is to be connected
with the device accordingly.
