Tamper switch
It is a UL Listing requirement that all control panels in a life safety system that
includes security functions have a tamper switch. When the EST3X control panel
is integrated with an EST3 network, install a 3-TAMP supervision switch to meet
UL requirements. Figure 32 shows the mounting location in the CAB6B.
Before installing the switch, refer to the 3-TAMP, 3-TAMP5, 3-TAMPRCC
Cabinet Tamper Switches Installation Sheet (P/N 387422) for additional
installation information and wiring instructions.
