First Line Of Protection

FORTEZA 500 / 300

1. Purpose

The purpose of Electro Magnetic Wave linear sensors “FORTEZA-500/300”, “FORTEZA-500T/300T” (below the sensor) is to protect perimeter sectors of different sites and to generate alarms when an intruder crosses a detection zone.

2. General Information

2.1. The sensor is a bistatic Electro Magnetic Wave device consisting of a transmitter and a receiver.

2.2. The principle of the sensor operation is to generate an electromagnetic field in the space between a transmitter and a receiver. The field forms a volumetric detection zone in the form of an oblong ellipsoid of rotation and registers the changes of this field when an intruder crosses a detection zone.

2.3. The wired synchronization is issued under the order (receiver and transmitter are connected by the synchronization cable) and without it-the standard equipment.
The wired synchronization permits you to realize a working of the receiver and the transmitter in a pulsed mode with a large porosity. It significantly increases the immunity interference.
The additional synchronization between neighboring sets permits to increase the tolerance to overlapping of the neighboring sites and to sabotage one.

2.4. The sensor is intended for continuous round-the-clock outdoor operation at an ambient temperature: “FORTEZA-500/300” is -40ºC…+65°Ñ, “FORTEZA-500T/300T” is -50ºC…+65°Ñ and relative humidity up to 98% at the temperature +35°Ñ.

3. Distinctive Features

3.1. No “dead zones” on detection.
3.2. Narrow detection zone.
3.3. The sensor is immune to strong electromagnetic fields (power lines up to 500 kV).
3.4. If the detection zone is specially prepared and the thresholds are adjusted the sensor can detect a crawling intruder.
3.5. Operation at a high level of snow up to 1 m
3.6. High interference immunity.
3.7. Minimal seasonal work at a protected sector.
3.8. There is a protection from storm discharge and high-voltage pickup.

4.Specifications

4.1. Length of the detection zone is 10...500 m.
4.2. The width of the detection zone is the following:
    - 3,5m when the length of a sector is 500m;
    - 2,7m when the length of a sector is 300m;
    - 1,9m when the length of a sector is 150m.
4.3. The minimum height of a detection zone is 1,9m at the maximum sector length.
4.4. Minimal duration of an alarm is 3 sec.
4.5. The sensor supply voltage is 9…30 V.
4.6. Maximum consumption current is 0,04 A.
