System Overview Intelligent Detectors
the standard EIA-485 connection like an ACS device and mounts easily in standard module
locations within the cabinet or external boxes. Refer to the Transmitter Module TM-4 installation
document for further information and installation instructions.
Universal Zone Coder - UZC-256. A circuit board, used for NAC coding applications, that
provides three NAC output circuits and up to 256 zone codes. Refer to the UZC-256 Universal
Zone Coder and UZC-256 Programming manuals for further information and installation
instructions.
Field Charger/Power Supply - FCPS-24, FCPS-24S6, FCPS-24S8. Compact,
cost-effective remote power supply and battery charger with a filtered, 24 VDC output that can
drive up to four Notification Appliance Circuits (NACs). The FCPS-24S6/FCPS-24S8 can also
synchronize the NACs. Refer to the FCPS-24 Field Charger/Power Supply Manual or the
FCPS-24S Field Charger/Power Suppply Manual for further information and installation
instructions.
Battery Charger - CHG-120. Designed to charge lead-acid batteries that provide emergency
standby power for a Fire Alarm Control Panel. Provides two (2) output circuits for connection to
multiple loads. Can be mounted into the CAB-4 Series backbox or the XLS-LBB Battery Box.
Refer to the CHG-120 Battery Charger manual for further information and installation instructions.
Liquid Crystal Display - XLS-LCD-80. An alphanumeric display module that is an ancillary
device which has two basic modes of operation. In Terminal Mode it acts as a display interface and
in ACS Mode as an alphanumeric annunciator. Refer to the XLS-LCD-80 Liquid Crystal Display
manual for further information and installation instructions.
Remote Fire Annunciator - XLS-FDU-80. An 80-character LCD that displays all panel
information remotely. Refer to the XLS-FDU-80 Manual for further information and installation
information.
SCS-8 Series Smoke Control System. The Smoke Control Station (SCS-8) module uses
eight groups of four annunciator points for fan shutdown control or other heating, ventilation or air
conditioning functions. The Smoke Control Expander (SCE-8) is used to expand the SCS-8 by an
additional eight groups of four annunciator points. Only one expander can be used per SCS-8. The
Smoke Control Lamp Driver Station (SCS-8L) module uses eight groups of four annunciator points
for fan shutdown control or other heating, ventilation or air conditioning functions. Must be
mounted in custom graphic annunciator panel. The Smoke Control Expander (SCE-8L) is used to
expand the SCS-8L by an additional eight groups of four annunciator points. Only one expander
can be used per SCS-8L. Must be mounted in custom graphic annunciator panel. For more details
on the SCS Smoke Control System, refer to the SCS Manual.
2.5 Intelligent Detectors
Introduction
Intelligent, addressable detectors provide analog information to the control panel on a Signaling
Line Circuit (SLC). This allows the control panel to continually process this information to
determine the status (alarm, trouble, maintenance, or normal) of each detector. Each detector
responds to an SLC address that is set in the detector head using built-in rotary switches. Each SLC
loop can support up to 159 detectors. The sensitivity of each intelligent detector can be
programmed (refer to Appendix C in the XLS140 Programming Manual for details).
NOTE: A blinking LED on an intelligent detector indicates communication between the detector
and the control panel.
