GLOBAL TAMPER CONNECTION
Note: The global tamper connections are very important.
The global tamper connections on the 832 and 832+ control panel are GT and AUX-, devices
should be connected between these two terminals to create a global tamper loop.
The 424 control panel does not have the GT terminal connection, so a spare zone programmed
as Tamper should be used to create the tamper loop.
