Supervised Inputs
Supervised inputs of the Quaestor-SZU Releasing Fire Control Panel are Class B, Style C Initiating Device Circuits
(IDC). Supervised inputs include the field terminals of MAN RELEASE, ABORT, REL. PRES. SWITCH and LOW
P. SWITCH. These inputs are supervised for open-circuit, short-circuit and ground-fault conditions.
Circuits operating on these terminals require a 6.8K Ohm EOL resistor, SHE80002 and a nominal, 470 Ohm trigger
resistor, SHE80003.
The figure below illustrates a typical supervised input connection on terminals of the Quaestor-SZU Releasing
Fire Control Panel.
