GENERAL DESCRIPTION
Figure 1-1.
The Federal Model SS2000SM (figure 1-1) is a
full-featured, programmable electronic siren and
light control system. State-of-the-art microprocessor
technology is utilized to produce a system with a
small, compact Control Head, and an Amplifier/
SignalMaster™ Control/Relay Unit which may be
remotely mounted. Programming of the various
features is done from the keys on the Control Head,
without disassembly or removing the unit from its
mounting location. When properly programmed, the
Model SS2000SM provides a highly versatile elec-
tronic siren and light system.
The SS2000SM produces wail, yelp, priority, and
hi-lo siren tones, as well as an air horn sound. A horn
ring transfer feature allowing horn ring control of
siren tones (Tap II) is also provided. Public address
(PA), with and without common microphone opera-
tion, and radio rebroadcast are available. Eight relay
outputs are available for control of light bars, other
auxiliary lights, and accessories. In addition, a full
feature SignalMaster controller is integrated into the
system.
Provision is made to allow installation of a user-
supplied switch, such as a foot switch, to activate
lights and siren in the pursuit mode.
This system provides the automatic, simulta-
neous light and siren activation required by some
laws. Momentary, push-on/push-off, or timed relay
operation can be selected. A security shotgun timer is
also provided to minimize the possibility of unautho-
rized shotgun release. The SS2000SM’s technology
allows variation of these features during program-
ming. The Control Head can be customized with an
assortment of replaceable function labels (supplied)
to identify the switches.
The SS2000SM may be installed in the trunk,
under the seat, or under the dash of any vehicle with
a 12 volt, NEGATIVE ground electrical system. The
siren circuits are protected from failure modes by an
in-line fuse that is replaceable without tools. Relay
outputs are protected by individual fuses. Connection
between the Control Head and the SS2000SM is via a
telephone-type, four-conductor cable with standard
modular phone connectors at both ends for simple
installation.
The SS2000SM can drive one or two 11-ohm
impedance high power (100 Watt) or low power (58
Watt) speakers. When two speakers are used they
must always be connected in parallel and in phase.
The SS2000SM controls the SignalMaster with
the top row of switches and/or the slide switch on the
remote control head. Directional and warning signals
can be generated on the SignalMaster as well as fast
and low power versions of these signals. Control of a
six lamp SignalMaster is also available.
Other advanced features of the SS2000SM
include:
• High degree of reliability and compact size
through the use of CMOS microprocessor and
other integrated circuits.
• Simplified installation and service through use
of plug-in cables and printed circuit boards.
• Relay outputs are individually fused with
standard automotive type fuses.
• A one-inch thin remotely mounted control head
operates all lighting and siren functions.
• The siren tones comply with SAE J1849 JUL89
for the following model: SS2000SM.
