Cherry Tampers The Cherry tamper switch located on the back wall of the cabinet
should be connected to terminals 18 and 19. The front tamper switch is also of Cherry
type and should be connected to terminals 20 and 21. The tamper switch has a cheat
feature that allows the switch to be inactive when the cabinet door is open. This is enabled
by pulling the tamper switch spigot into a forward position. Both are wired as normally
open.
●
Cabinet Tamper The Class IV system has an additional cabinet tamper, which is
configured using a cabinet zone tamper. By default, zone 1 on Class IV software is assigned
as a cabinet zone tamper. The Class IV system cabinet has an inner and an outer skin,
which are wired back to zone 1. A SHORT or DISCON on this zone will generate a tamper
signal. The cabinet zone type is normally closed and terminated with a 2k2 resistor.
