The 2112 operates ONLY on 16.5 VAC.
DO NOT power the 2112 with 24 Volt
transformer or source voltage.
Use the supplied power transformer, 16.5
VAC, 20 VA (or UL listed equivalent) to
power the 2112. DO NOT power any other
devices (electric strikes, magnetic locks
etc.) from the 2112’s power transformer.
J1 jumper needs to
be set for RELAY 3
when used.

The Tamper input is not defined yet.
The concept is that in input here
will generate some type of
transaction or notification on the
app. Maybe tie in with gate operator
to show that the gate is held open,
but we have not defined this yet
