Sigma Category 1 Automobile Alarm User Manual


 
The ultrasonic interior detection system also employs a movement/time method where a
cert ain amount of movement in a given time is also required to cause a trigger.
This method of detection offers a high level of protection against false alarms that are
commonly associated with other systems that employ inferior methods of detection.
Arming the Security System Without Ultrasonic Interior
Protection*
W arning: Impreza and Forester models from 2003 model year and Legacy models
from 2004 model year are equiped with double-locking doors. People should not be
left inside these vehicle s with the alarm armed under any circumstances. When
armed, the vehicles doors double-locked automatically and cannot be opened
internally! If armed in error, with an occupant in the vehicle, the system should be
disarmed and a door must be opened and shut to prevent auto-rearming and
locking occuring.
Arming the security system without ultrasonic interior protection will be necessary, yet still
provides limited protection, if you wish to leave animals inside the secured vehicle or the
windows/sunroof open whilst the vehicle is left unattended. Sensible safety precautions
should be exercised if considering these actions! To do this:
Turn the vehicle s ignition o n , give the radio transmitter button a quick press.
The dashboard mounted LED will flash once.
Turn off the vehicle s ignition immediately.
Vacate the vehicle closing all doors, boot and bonnet.
Give the radio transmitter button a quick press, whilst standing near the vehicle.
The security system will acknowledge arming with 8 flashes of the vehicle s hazard
warning lights, instead of the normal 4. The doors will double-lock as normal.
Ultrasonic interior protection will be restored the next time the security system is
armed in the normal way.
* Also possible using the multifunction keypad. See page 11 for det ails.
Automatic Immobilisation and Starting the Vehicle
The alarm system is armed and disarmed by your radio transmitter, however the vehicle
also has immobilisation circuits that set automatically after the ignition is switched off.
This is a Thatcham MIRRC requirement so that the driver cannot forget to set the
immobilisation system. Although the vehicle is immobilised, the alarm system is not
armed and the interior, doors, boot and bonnet circuits are not protected until the radio
transmitter button is pressed to arm the security system.
Impreza/Forester 1999-2002 MY and Legacy 1999-2003 MY.
When the ignition is turned off on these vehicles, the dashboard mounted LED will be
switched to a constant on state for 30 seconds (dependent on programming). During this
LED on time you may start the vehicle. After this time the LED extinguishes to indicate
that both immobilisation circuits have armed automatically. On disarming the security
system, the dashboard mounted LED will again be switched to a constant on state for 30
seconds (dependent on programming). During this LED on time you may start the
vehicle. Af ter this time the LED extinguishes to indicate that both immobilisation circuits
have armed automatically.
