Electro-and magneto-contact sensors are used for second-line protection.
3. P assivnye infrared sensors (motion detectors).
Optoelectronic infrared WIDE passive detectors are widely used when blocking rooms for different purposes, as the third line of defense in the systems of objects by technical means signals tion.
Tactics of detectors based on the features of their device and the principle of work.
The basic structural elements of the detector are:
-- optical system of the collecting lens (mirror or Fresnel) with a common focus, which forms a sector of sensitivity, located fan (on to lichestvu lenses in the system) in the field races tribution (background) infrakra snogo radiation from the walls, blocking ty, heating radiators and other objects within premises;
-- pir-element sensitive to infrared range of thermal radiation, which is placed in the pho Coos optical system;
-- electronic circuit for signal processing adapted to the background th level of infrared radiation indoors.
When intersection admission to (input, output) at least one of the second tori CONTRACT PERIOD sensitivity of the optical system body, the infrared radiation Coto rogo above background, it raised.With em sharp increase (especially border incursions) amplitude inf rakrasnogo flow (surge). This signal is perceived pir -element is processed electron gradated and executive elements cops, then given signal "Trevi ha.
It is possible to specify the number (1, 2, etc.) while crossing the sensitive sectors of the body which will be given a signal "anxiety".
With tse pour on Niya higher sensitivity stvi CONTRACT PERIOD certain types of detectors practiced use of dual or even quadrupled in single package pir-elements, which form additional sub-sensitive to each sector.
Depending on the implementation of the one kticheskih functions of optical systems are manufactured in various versions of the location of lenses and can form a variety of configurations zones of detection. The most common They are bulky, curtains, barriers - for wall mounting and cones - to ceiling.
Optical system izveschate MDL provides:
-- create a zone of three-dimensional configuration radial-tier arrangement of lenses, used to lock the premises by volume. These detectors provide intrusion detection at the object through Window and door openings, moving earlier hiding in a room the offender, etc. (Fig. 3. 3 a);
-- Education odnoveernoy vertical zone detection ( "Blind" Fig.3. 3 b), used for local protection of window and door openings, paintings, exhibited in the car tinnyh galleries, as supplementary HYDRATED line signaling ( "trap") that separates the vertical part of the premises "blind", which contains more valuable on borudovanie;
-- formation zone in the form of a "corridor" (reminiscent of "blind", but with greater length of detection zone), used as a rule to block spaces along the corridors, of which there are entrances to the premises or from the lobby (Figure 3.4) ;
-- a zone of detection conical shape (Fig.3.5), used to block the approaches to the detached objects in the room or museum expo there. The detector is mounted on the wing on, and exhibit in the center of the zone of detection. It should be borne in mind that the distance from the border zone of detection to the exhibit should be at least 1,5 m .
When vybo re for monta Ms. ARE using such detectors, tactical and those chronically data Coto ryh should fully enforce the requirements for reliable locking of an object (the range of detection zone, its volume characteristics, the possibility of varying the angles of vertically On tilt and horizontal rotation in the planes, the optimal mounting height).
To avoid triggering the infrared sensor caused by movement of animals (dogs, cats, rats, etc.) implemented several methods of protection:
1) lower part of the lens is closed do not let the filter infrared radiation, ie, given a zone of passage for animals;
2) sets the number of sensitive sectors, while the intersection of the body which is triggering the sensor;
3) specified threshold of infrared radiation which is triggering the sensor.
Despite the relatively high background security detectors, is not recommended to install them in places accessible to direct sunlight. In AOR tries detection detectors (in the protected period of time) should not operate heating fans and air conditioners,
Avoid "dead" zones of protected areas should not be blocked with furniture, screens and various re towns.
Adjusting the focus areas of detection detectors made empirically on the light tovym indicators on the latter. After setting off the detector light indication chaetsya.
Power detectors (about 12) is DC voltage from the AUC or auto nomnogo block.
In order to prevent removal detectors in unguarded period of time (cables removed from the invasion of) the supply voltage is fed to them around the clock to the work of trails antimaskinga and "Sabotage".
Detectors constructively you complemented plastic building sah equipped unit contacts "Sabotage" and LED signal "anxiety". When the mirror optics, "window" sensory input is protected by appropriate filter, which transmits infrared radiation. In other cases, the protective element "window" is Xia Fresnel lens.
