XLS140 Installation Manual Form Number 95-7673-3 P/N 51927:C  12/06/2005  19
Optional Devices System Overview
VP-2B or MP-1B (with DP-1B)  For covering top row(s) of backbox if control panel is mounted 
in a lower row.  MP-1B is also used to mount panel circuit modules. 
2.4  Optional Devices 
Several optional components can be installed within the XLS140 system. This list provides only a 
sample of common equipment; for a complete list of what is available, refer to Appendix C 
“Compatible Equipment” and for a list of conventional equipment, refer to the Device 
Compatibility Chart. 
Network Control Annunciator - XLS-NCA.   Provides a text-based, 24 VDC powered, 
display and control device for XLS-NET. It incorporates a large LCD display and a silicone-rubber 
QWERTY keypad. It will display all events from the system. 
Network Control Module - NCM-W/F.  The NCM is an interface between the panel and 
XLS-NET.  It comes in two models: wire and fiber-optic cable. Refer to the NCM-W/F Installation 
Document for more information and installation instructions.
Loop Expander Module - LEM-320.   The LEM plugs into the control panel, expanding the 
board’s function to control two Signaling Line Circuits (SLCs). Each XLS140 can have one LEM. 
Refer to Section 3.5 “Installing the Control Panel” for installation instructions.
Auxiliary Power Supply - APS-6R.   The optional Auxiliary Power Supply is a 150W 
cabinet-mounted power supply, designed to power devices that require filtered, non-resettable 
power, such as NAC modules, and addressable Honeywell appliance circuit modules. The APS-6R 
provides three 24 VDC output circuits (6 A total in alarm, 4 A continuous): two power-limited 
circuits (3 A each) and one non-power-limited circuit (6 A). Refer to the APS-6R Instruction 
Manual for further information and installation instructions.
Addressable Charger/Power Supply - ACPS-2406.   The optional ACPS-2406 is an 
addressable loop-based power supply and battery charger. This cabinet-mounted unit provides four 
individually addressable Notification Appliance Circuits. In addition, each circuit can provide 
notification appliance synchronization without an additional module. The unit charges 7 to 25 AH 
batteries with full supervision. The ACPS-2406 provides up to four 24 VDC (filtered) output 
circuits (2.5 A max each, 5.0 A total continuous, 6.0 A during a fire alarm
). Refer to the 
ACPS-2406 Instruction Manual for further information, installation instructions, and battery 
calculations.
Batteries and Battery Boxes.   The control panel uses only sealed lead-acid batteries for 
standby power. Maximum battery capacity is 55 AH (ampere-hour). Minimum battery capacity 
depends upon the system configuration; absolute minimum is 12 AH. CAB-4 Series backboxes 
provide space for two 25 AH (or smaller) batteries. Use external battery boxes if the installation 
requires larger capacity batteries. Battery boxes mount directly below the main cabinet. Battery box 
model XLS-LBB holds batteries up to 55 AH. Refer to Section 4.2 “NFPA 72-1999 Central or 
Remote Station Fire Alarm System (Protected Premises Unit)” and  Section A.3 “Calculating the 
Battery Requirements” for further information. See Battery/Peripherals Enclosure document for 
backbox measurements and installation instructions.
Universal Digital Alarm Communicator/Transmitter (UDACT). Transmits system status to 
UL-listed Central Station Receivers over a public switched telephone network. Mounting is in a 
CAB-4 Series backbox or remotely in the ABS-8R enclosure. The unit connects to the EIA-485 
annunciator port and 24 VDC (nominal) power. Refer to the UDACT Instruction Manual for further 
information and installation instructions.
Transmitter Module - TM-4.   The TM-4 includes three reverse polarity outputs and a Fire 
Municipal Box Trip in a single module. It provides a means for the FACP to control Alarm, 
Trouble, and Supervisory reverse polarity outputs (15 mA, 24 VDC nominal) or a Fire Municipal 
Box Trip output. All output circuits are supervised. The Transmitter Module communicates over
