Quaestor-SZU Releasing Fire Control Panel - Installation and Operation Manual
Revision E03.04
60 of 155
This section provides procedures for installing and operating supplementary devices of the Quaestor-
SZU Releasing Fire Control Panel.
Reference Appendix A, Specifications to identify operating parameters of these devices.
Status Units
Status Units extend indications and controls of the Quaestor-SZU Releasing Fire Control Panel to other locations
within the fire protection system to make operation of the system more practical. A maximum of seven Status Units
can be connected to each Quaestor-SZU Releasing Fire Control Panel in a releasing area.
Status Units are supervised for open-circuit, short-circuit and ground-fault conditions. Status Units are compatible with
all models of the Quaestor-SZU Releasing Fire Control Panel. The Status Unit requires a data connection and 24
VDC to operate. Status Units can also be powered by the AUX 24V output or an auxiliary 24 VDC source that is
listed for Fire Applications with Regulated and Power Limited Outputs. The maximum line impedance is 120 Ohms.
The J2 Jumper Connection
Status Units contain a push-on-jumper at PCB location J2. The J2 jumper is located on the left-side of the Status Unit
PCB. The J2 jumper is a terminating resistor for establishing the end of the data line. Connect the J2 jumper to the last
Status Unit when multiple Status Units are connected in a data line. Connect the J2 jumper when operating one
Status Unit.
A common earth ground is required between all Status Units and each fire control panel. Maintain correct polarity
when connecting the Status Unit to the Quaestor-SZU Releasing Fire Control Panel. Status Unit terminal-
connections are polarity sensitive.
