For The
Common
False Alarm
ES250
Interior Ultrasonic Sensor
As crime becomes more and more
sophisticated, so must the ways of foiling it.
Anyone who has invested heavily in a vehicle
asset needs to protect that investment, of
course, but to protect it far further than the
range of choices which criminals have
available to them.

Aren't we tired of hearing vehicle alarms blaring for no apparent reason? They are extremely irritating and
they intensify our noise pollution but, far worse when the day comes that you need to be alerted, you
probably wouldn't take an alarm like that seriously. At Sanji we take this matter very seriously. So that's why
we developed the super miniature ES250 ultrasonic sensor. The sensor works like an internal radar system,
continuously sending and receiving information about your vehicle's interior. After careful analysis of the
received data, the ES250 will decide whether to activate the alarm or reject the data as in the case of common
air disturbance. The ES250 sensor is so advanced that a patent on its electronic design has been granted.
The Sanji ES250 uses patented technology to discriminate between false alarms and real intrusions. The
ES250 continually monitors the size and the speed of the moving object and if both fall into pre programmed
parameters the ES250 will sound the alarm.
There are many reasons for false alarms but the most common and the one that most ultrasonic sensors do
not address is the problem of rising air bubbles. On a hot day air bubbles form inside the vehicle and begin
to rise. As they rise they tend to reflect the 40 KHz signal and it appears to the sensor that an intrusion has
occurred. The Sanji ES250 is very smart in that it will measure both the speed and the mass of these air
bubbles and based on its intelligence it will be able to reject these as genuine intrusions. Although the Sanji
has this capability it is still highly recommended that the vehicle windows remain closed at all times.
The ES250 is fully compatible with all Sanji Alarm and Alarm Immobilzer Systems and can also be fitted to
vehicles that have factory fitted alarm systems.
