    BASIC OPERATION This unit is a combination passive-inirared sensor and microwave sensor ,

    both contained in a single package. The unl! wili go into alarm when both sensors detect intrusion at the same time.

    The PIA section operates by detecting a rapid change in hnnperature when an intruder crosses a protected area When a boam experiences a change in heat (projected back through the lens). a pul~e is generated by the sensor element. The microwave transmitter sends out short burs:s of rf energy, and the receiver aete~s changes in the re:umed s:gnal caused by motion within Its coverage area.

    The microwave section is unaffected by visible light, a!r drafts, or tempera-ture changes (as from soace heaters or air condit ioners, for elCamcHe), but is sensitive to motion . Stronc vibrations can be :roublesomc. Microwave signals may pass through non-metall ic walls and windows. Infrared is virtual ly unaffected by vibration , and will net penetrate walls or windows.

    Thus the two technologies complement each other, and ft is the combina-tton ol '\he two that provides an inherent immunity to faise alarms. Dual technology is ideal for usa in i10stila environments. Since beth must trip to caLJSe an alarm, instaha!ion is easier and requires less discipl ine.

  • PIR ZONE DIMENSIONS Regardless of the lens patlern selected , or the number ot PIR beams

    produced by the lens, the relative proportions of beam width , beam height, beam separation, and zone width always remain the same and are illustrated in Fig . 1. Note that beam and zone dimensions at any distance may be calculated by the following formulas. Beam Width "w" (in.) = Distance "d" (ft.) x 0.4 Beam Separation "s" (in.) = Distance "d" (ft.) x 0.4 Beam Height "h" = 2 x Beam Width "w" Zone Width "z" "' 3 x Beam Width ''w" Examples:

    At 10', a zone is 8" high x 12" wide. At 30', a zone is 2' high x 3' wide.

    DETECTION PA !TERNS Figure 2illustrates maximum PIR and microwave detection patterns super-

    imposed on each other. PIA detection patterns are adjustable, within limits, both vertically and horizontally (see ADJUSTING THE COVERAGE AREA for detailed adjustment procedures).

    The microwave detection patterns shown are for tree space. In practice , when confined by walls and ceil ings, reflected waves tend to flood the area, providing voiumetric coverage . Furthermore, when used In long, narrow corridors, the effective range may be extended by as much as a factor of 2 due to the guiding effect that the corridor has on microwave energy. Microwave detection range is adjustable. Reducing range , however , will reduce all other dimensions proportionately. Insensitive Areas

    The insensitive area is that area directly beneath the unit within which an intruder is undetectable. It is shown as a shaded area in the side-view detection pattern that follows, and assumes that an intruder will be at least 5' tall and that the protected area is not accessible by crawling or crouching . The srze of the insensitive area will increase as the mounting height in-creases (see Fig . 2b) . Nevertheless, it may be necessary to increase the mounting height in order to avoid an object that could obstruct the coverage pattern . See INSTALlATION: Reducing Insensitive Areas.

  • STANDARD LENS The lens patterns illustrated are adjustable, within limits, both vertically and

    horizontally (see ADJUSTMENTS: Aiming the Beams for detailed adjust-ment procedures). Settings can be quite critical. Examples shown herein are typical and will not apply to all cases. I>Jways test the coverage pattern after the unit is installed (see TESTING THE COVERAGE AREA).

    The supplied lens will perform best in typical applications, thus it is factory installed. Following are its specifications. Zones: M7100STE. 15 (31ayers: 7!7/1 zones); M73DDSTE, 14 (3 layers: 7/6/1 ) Ma.ximum Coverage: M7100STE, 40'L x 40'W; M7300STE, 70'L x 60'W Field of View: 80" Recommended Mounting Height: 6 to 8' Minimum Mounting Height: 6' Maximum Mounting Height: 12'

    Note: (1) Should the lens become heavily soiled , it may be cleaned using lukewarm water and a mild detergent. To dry, use a soft lint-free cloth or allow to air dry. (2) If the standard lens does not suit the application , select another available lens. Slightly loosen the lens clamping screws inside the trent cover and slide out the lens. Then slide in the replacement lens with grooved side facing inward, make the required adjustments and tighten the clamping screws just enough to secure the lens. Do not overtighten! 6

  • INSTALLATION CHOOSING A SUITABLE LOCATION

    The unit may be either wall mounted or comer mounted. Corner mounting is generally recommended as greater coverage may be obtained. Select a rigid surtace that is relatively free of vibration.

    Positioned the sensor with respect to access doors or windows so that an intruder will pass across its field of view, not directly toward or away from it. Avoid areas containing devices that may pose a chronic problem to either sensor. For the dual-technology feature to be truly effective in rendering the unit free from false alarms, neither sensor should detect intrusion under normal conditions. Note: The unit is shipped from the factory with Jumper J1 in the Alarm position.

    In selecting mounting height, aiming, and range, also consider the follow-ing:

    1. the size and shape of the area to be protected. In a large or irregularly-shaped area, the use of two or more units may be advisable tor volumetric coverage;

    2.. tho PIR lens installed; 3. objects that may b lock detection ; 4. animals in the protected area; and

    5. an intruder's likely path , usually determined by the location of a door or window. MOUNTING THE SENSOR

    To remove the trent cover, Insert the blade of a screwdriver into the s
