EXT2 Extended Range Antenna (optional)
The optional EXT2 is a tuned, coaxial antenna, designed to be used with the MS5500
security system to increase transmitter range. When properly installed, the EXT2 will add
greater installation flexibility to the system, allowing the antenna to be placed high in the
vehicle to achieve maximum range.
Open the cover of the MS5500 main unit and plug the 2-Pin EXT2 connector into the
antenna port located directly on the alarm board, next to the existing antenna. Be sure that
the side of the connector marked with a black dot (center conductor) is facing the side of the
alarm opposite the alarm 14-Pin main connector.
Run the EXT2 cable through the same hole used for the existing antenna. Once you have
replaced the cover, twist the existing antenna around the EXT2 cable to prevent any
potential RF interference.
Route the EXT2 up as high as possible inside the vehicle and be sure to avoid running the
exposed end of the cable along any wire harnesses.
Logic Sensor II
The Logic Sensor II, included with the system, is designed to be mounted in the interior of
the vehicle using a tie wrap or double sided tape. Be sure to avoid mounting the sensor to
sources of strong electrical interference such as cellular phone transceivers or the vehicle’s
engine computer.
Suggested mounting locations are an air conditioning duct, or a dashboard or center
console support brace.
Shock and Motion
When mounted horizontally, the Logic Sensor II will detect both shock and motion. The
Logic Sensor II’s motion detection is most effective on the axis on which it is mounted,
which means that careful selection of the mounting location of the sensor will help to
insure it’s effectiveness. See Jumper Selections to select motion sensitivity.
Shock Only
When mounted vertically, the Logic Sensor will detect shock or impacts to the vehicle
only and will be unaffected by slow rocking movements of the vehicle. This is especially
useful in vehicles that are normally parked in areas subject to high wind or parked in
tall parking structures that tend to move or sway.
