Field Cabling
Field cabling of the Quaestor-SZU Releasing Fire Control Panel includes terminal connections for detection zones,
supervised inputs, Notification Appliance Circuits (NACs), releasing device circuits, relay outputs, AUX 24V power
and Status Units. Connect all field wiring to the single row of terminals along the top of the fire control panel.
Terminals accept wiring from 14 to 18 AWG. Wiring outside of the fire control panel must not be routed across the
front surface of the fire control panel.
Detection Zones
This section describes connections for detection zones of the Quaestor-SZU Releasing Fire Control Panel.
Detection zones are Initiating Device Circuits (IDC). Initiating Device Circuits of the Quaestor-SZU Releasing
Fire Control Panel are power limited and include:
Detection Zones Include connections for ZONE 1, ZONE 2 and ZONE 3
Supervised Inputs Include connections for MAN RELEASE, ABORT, REL. PRES. SWITCH and the LOW
P. S WITCH
Remote Control Inputs Remote Control connections ROV, & FLT, RST are used on the Quaestor-SZU
Releasing Fire Control Panel to activate the manual extinguishant disablement function.
Mode Select
Mode Select connections are unused on the Quaestor-SZU Releasing Fire
Control Panel and are designated as No Connect (NC)
terminals.
Detection zones of the Quaestor-SZU Releasing Fire Control Panel provide a nominal 24 VDC for powering
conventional detectors and pull stations. Detectors must be wired in a daisy-chain without T-Top connections.
Detection zones are supervised for open-circuit, short-circuit and ground-fault
conditions with the installation of the
6.8K Ohm EOL resistor, SHE80002. Place the 6.8K Ohm EOL resistor across the last device in the detection zone
circuit to provide this supervision.
Pull stations authorized for use with the Quaestor-SZU Releasing Fire Control Panel are non- addressable and
UL listed.
Zones of the Quaestor-SZU Releasing Fire Control Panel operate NFPA 72 Class B, Style C or NFPA 72, Class
B, Style B. Style C
devices provide trouble conditions for direct shorts and opens on zone loops. Style B devices
provide alarm conditions for direct shorts and trouble conditions for opens on zone loops.
Change the default operation of Style C to Style B by using the appropriate configuration code. Set the following
configuration code on the fire control panel to provide a Class B alarm when a short circuit condition occurs
in Zone 1, 2 or 3:
• Set C71 to alarm when a short circuit condition occurs in Zone 1.
• Set C72 to alarm when a short circuit condition occurs in Zone 2.
• Set C73 to alarm when a short circuit condition occurs in Zone 3.
The maximum number of detectors per zone is device and manufacturer dependent.
