Safety Messages
Read and understand these procedures before installation. All work should be performed
by a properly trained Technician or Electrician that is qualified to do electrical work. You
must follow electrical and ESD precautions. If any of the electronics are handled without
static protection, the electronics may be damaged.
Listed below are important safety instructions and precautions you should follow:
Important Notice
Federal Signal reserves the right to make changes to devices and specifications
detailed in the manual at any time in order to improve reliability, function or design. The
information in this manual has been carefully checked and is believed to be accurate;
however, no responsibility is assumed for any inaccuracies.
Installation and Service
• Electrocution or severe personal injury can occur when performing various installation
and service functions such as making electrical connections, drilling holes, or lifting
equipment. Therefore, only experienced electricians should install this product in
accordance with national, state and any other electrical codes having jurisdiction.
Perform all work under the direction of the installation or service crew safety foreman.
• The sound output of sirens is capable of causing permanent hearing damage. To
prevent excessive exposure, carefully plan siren placement, post warnings and restrict
access to areas near the sirens. Sirens may be operated from remote control points.
Whenever possible, disconnect all siren power including batteries before working
near the siren.
• After installation or service, test the siren system to confirm that it is operating
properly. Test the system regularly to confirm that it will be operational in an
emergency.
• If future service personnel do not have these warnings and all other instructions
shipped with the equipment to refer to, the siren system may not provide the intended
audible warning and service personnel may be exposed to death, permanent hearing
loss, or other bodily injury. File these instructions in a safe place and refer to them
periodically. Give a copy of these instructions to new recruits and trainees. Also, give
a copy to anyone who is going to service or repair the sirens.
Operation
Failure to understand the capabilities and limitations of your siren system could result in
permanent hearing loss, other serious injuries or death to persons too close to the sirens
when you activate them or to those you need to warn. Carefully read and thoroughly
understand all safety notices in this manual and all operations-related-items in all
instruction manuals shipped with equipment. Thoroughly discuss all contingency plans
with those responsible for warning people in your community, company, or jurisdiction.
Read and understand the information contained in this manual before attempting
to install or service the siren.
Pay careful attention to notices located on the equipment.

General Description
Upgrade Manual
Federal Signal www.fedsig.com
General Description
Introduction
This manual describes how to upgrade your DCFCB from a one-way siren controller to a
two-way siren controller.
DCFCBs are one-way controllers for mechanical sirens or similar devices. The DCFCBs
receive commands through a radio or other communications, but do not provide any
status back toward the activation point. DCFCTBs are two-way control and status
monitoring controllers. These units interface to two-way radio systems, which provide
two-way control and monitoring capabilities. Federal Signal has a pre configured kit for
upgrading DCFCB cabinets to DCFCTB cabinets. For VHF upgrades order Q-DCFC1-2H;
and for UHF upgrades, order Q-DCFC1-2U.
NOTE: Antenna is not included. You must order antenna separately.
Qualications
You must be a properly trained Technician or Electrician in order to install this product.
You must be an Engineer or Technician with radio equipment capable of deviation
adjustment and VSWR test. Typically, a radio shop has this capability.
Required Equipment
You need the following:
• Standard Technician’s Tool Kit.
• Bucket Truck and Ladder may be needed to access the site. Access for antenna
installation is required.
• The One-Way to Two-Way Kit for DCFCB.
• VHF part number: Q-DCFC1-2H
• UHF part number: Q-DCFC1-2U
NOTE: For pricing and availability, call Customer Care at 800-548-7229.
• Some installer parts are required.
NOTE: These are not part of the One-Way to Two-Way Kit for DCFCB.
For installation instructions on the Yagi and Omni Antennas go to the Federal Signal’s
website. Typically, additional antenna mounting parts are needed. The required parts are
listed in the manual and may change according to local code.
The following are some of the typical parts required. Typically, these are supplied by the
electrician.
• Two AWG ground wire for or grounding antenna to ground rod.
NOTE: Treat ground wire connections with anti-oxidant compound.
• Ground rod and tools required to install the ground rod.
• Four 3/8-inch by 4-inch lag bolts
• Four 3/8-inch washers

8
Introduction
One-Way to Two-Way Kit for DBFCB
Federal Signal www.fedsig.com
• Four 3/8-inch lock washers to mount antenna bracket to pole.
• Compression C-tap #2AWG
• Twenty-five clips, coax nail for nailing down the antenna cable
• Ten UV-resistant tie wraps for tie wrapping the cable to the bracket
• Tape, mocap, silicone insulated for sealing the antenna connectors.
NOTE: Seal all connections.
• Disposal bag or box to put the old parts into that will be removed.
• Radio service monitor and VSWR tester required for the radio system. Typically, radio
shop supplied.
Recommended Cables
When equipped with radio from the NX-5000 Series in your two-way RTUs, Federal Signal
recommends purchasing the following cables for computer programming:
• RIB FIF-12A USB interface cable
• CT-104A interface cable
Use the RIB FIF-12A USB cable to connect to your computer. Use the CT-104A cable to
connect from the RIB FIF-12A USB cable to the radio.
