The IMPASSA Strategy:

Detect. Defend. Defeat.
IMPASSA is the newest, next
generation wireless security system
from DSC. IMPASSA comes with
the defense and offense needed to
protect the ‘king’ – the home and
homeowner - including:
•
An integrated HSPA (3G) cellular
communicator for high speed,
reliable and secure alarm
communications.
•
The flexibility of a distributed
approach that allows wireless
devices to be located wherever
needed for optimal protection.
As easy as setting up a chessboard,
installers can now deliver a full-
featured home security solution in
minutes by easily enrolling a range of
compatible wireless devices into the
IMPASSA security system.
IMPASSA -- Checkmate.
Defensive Strategy -
Integrated 3G Cellular
Communicator
As any good chess player knows,
looking many moves ahead is
critical for a checkmate. As more
homeowners transition away from
traditional phone lines towards VoIP
(Voice over IP) or mobile wireless
phones for communication, IMPASSA
delivers an alternate communication
path using the cellular network.
In addition, IMPASSA includes
a more traditional phone line
communicator using the Plain Old
Telephone Systems (POTS).
The IMPASSA integrated
communicator uses proven 3G
technology. This not only allows for
faster data-transmission speeds,
but provides a longer lifecycle as
cellular providers begin to phase out
their GSM (2G) networks. Just like
a mobile phone, IMPASSA displays
the cellular signal strength to help
determine the optimal mounting
position within the home. For the
homeowner’s convenience, the real
time clock updates the time and
date via the cellular communicator.
The Flexibility
of a Distributed
Wireless System
Because IMPASSA is a distributed
wireless system, installers have the
flexibility of positioning the panel
away from the premise’s entry point.
This allows for the installation of the

Make your Moves Easily with IMPASSA
Once you have a good strategy in place, moving chess
pieces should be quick and easy – and it is with the
IMPASSA 2-Way Wireless Security System and wireless
compatible devices. With only one wire needed for AC
power, installers need to drill fewer holes and pull fewer
wires, reducing on-site time, which leads to increased
productivity and revenue. This benefits the homeowner too
because it means minimal disruption to the home and less
waiting around during the installation.
Using the IMPASSA 2-Way Wireless Security System
also reduces the time spent enrolling compatible wireless
devices. Installers confirm Electronic Serial Numbers (ESN),
zone numbers and zone type through a series of user-
friendly screens.
In addition, IMPASSA’s template programming feature allows
installers to quickly program basic functions by just entering
a 4-digit code. Codes exist for pre-defined zone definitions,
reporting code formats, communication call directions and
DLS setup. Finally, the installer enters the monitoring station
telephone number and account code, DLS access code,
entry / exit delays and installer code.
