Anti-Vandal^®

The Anti-Vandal^® system is a unique protection system, which is present in the PES^® sensors. Because the guards try in many cases to destroy the sensors so that their work cannot be controlled, the TOMST^™ Company makes sensors that are resistant to extreme conditions as well as contains the Anti-Vandal ^™ system. Thanks to the ANTI-VANDAL^® system, all sensors are capable of recording all attempts of its destruction. As soon as the sensor is dropped, if there is power surge, short circuit or extreme temperature or microwaves present, these events will be saved in the sensor's memory and after data from the sensors are downloaded to your computer, you will be immediately notified by:

Point rating is dealt with in the next section and represents the typical setting. Your sensor may have other point rating of individual Anti-Vandal events, as well as diffeent Anti-Vandal warranty. You will find more information about your sensor in the sensor window.

Anti-Vandal^® detects:

• Falls

  The sensors differentiate between various types of falls. Very small drops that come about unintentionally, for example, when the sensor falls from the table, are not registered by the Anti-Vandal^™system. Anti-Vandal^® point ratings:

  Small drop	1 AV point
  Middle drop	10 AV points
  Big drop	100 AV points

• Short circuit

  The Anti-Vandal^™system detects all intentionally short circuited reading probe. The short circuit will be recorded, if it lasts longer than 30 seconds. Thanks to this setting, accidental short circuits that can occur when the guard has the sensor in his pocket with his keys, will not be recorded. Points rating:

  Short circuit

  10 AV points

  In case the short circuit happens repeatedly at times between downloading data from two chips and the overall duration of the short circuit reaches half a minute, this is recorded in the report as one event.

• Power surge

  The system senses that there is an external power source connected to it with voltage greater than 4 Volts. Power surge may be due to power from batteries or other power source, for example, the regular power grid. Point rating:

  Power surge

  100 AV points

  D) ESD - Electrostatic discharge

  Electrostatic discharge (arcing) can occur, when the individual handling the sensor, is dressed in synthetic fibre clothing, walks over a carpet made from synthetic fibres, or gets up from a chair covered with synthetic leather and is therefore "charged" with static electricity. If then the sensor touch-contacts a metal surface, this may result in ESD.

  If ESDs are frequent occurences, we recommend you change the the guards' uniforms material, or eliminate all potential ESD causes from the workplace

  Point rating: 20 AV points

• Extremely high and low temperatures

  The Anti-Vandal^™system among others, continually controls even the sensor's temperature. If its temperature drops below -10°C or exceeds 50°C, the sensor will notify you with a warning tone of the event after the data is downloaded into the PC. If the temperature drops to -30°C or exceeds 60°C, a warning signal will be triggered. By exceeding these temperature, you are voiding your warranty.

  When temperature exceeds 60° C, the sensor emits a Fire! signal, until the temperature drops back to below 60° C If there is such an extreme overheating, the sensor must be cooled immediately! Should the temperature be increasing further, there is the danger that the battery may explode. If the sensor is exposed to an extremely hight temperature, it has to be sent to the manufacturer to be checked.

• Microwaves

  The PES^® sensors are resistant to damage by microwaves and as the only product in the world and even record attempts to destroy them microwave ovens. After transferring data to the computer, the Anti-Vandal^®system will notify you of the event.

  In some instances, when the sensor is placed in a microwave oven in a certain position, this event may be identified as small drop.

• Water resistance

  The PES^® sensors are water resistant to a depth of 1m.
