Based on analog and digital ASIC technology, the system controls the eye (pyro) sensor of the PIR to form a protection pattern.

When an intruder crosses the pattern made by the fresnel lens, the pyro will detect the infrared energy change and activate the transmission of the sensor.Sensitivity: t= 1.1 C @ 0.9 m/sec

( t= 2 F @ 3 ft/sec)For a correct installation, the proper selection of fresnel lens is important to maximize the likeliness that an intruder crosses the pattern.

Fresnel Lens

The spherical lens is divided into several optical groups of lenslets.

1) Look-Down (Creep) Zones which detect motion directly under the sensor. These can be deactivated by either removing the Mirror (Default Fitted).

2) Long Range FrontLenslets can detect up to 18 meters in front of the PIR. Also these can be used as curtain lens when fitted with the curtain MASK.

3) Wide angle lensletswhich detect a 140 degree view around the center of the sensor.

See the pattern diagrams of the detection areas.(2.1m mounting height)

Look Down Mirror: This mirror is mounted onto the bottom housing fitted standard in all units. Remove this Mirror to disable the lookdown zones.Curtain Mask: This is a plastic piece that is fitted under the lens, masking all of the side zones and enabling only the curtain zones to be activated. In order for all the zones to be enabled, install without the curtain mask.Jumpers: 4 Jumpers for all the settable options are included with the unit, which enables the installer to select any mode, right out of the box.

OPTIONAL ACCESSORIES Corner Mounting Tamper Bracket: Optional to enable the back tamper to work when mounted onto the corner.

Concerns: Architect/Engineer SpecificationsAffects: PYR-2023 Microwave/PIR Intrusion DetectorDated: May 28, 1998The Intrusion Detector[s] shall operate on the Verified Intrusion principle using combined Passive Infrared (PIR) and Microwave Intrusion Detection technologies, and shall be Listed by Underwriter's Laboratories, Inc., and FCC Certified to operate in the 10.525 Ghz band in the United States.

[Each] [The] detector shall provide the detection, signal processing, alarm relay, and operating power circuitry in the same enclosure; and shall provide an alarm relay actuation upon the simultaneous detection of an intruder moving into or through its combined protection pattern. The enclosure shall be ready for surface and/or corner mounting, and shall be capable of mounting to a compatible Gimbal Mount or Low Profile Swivel Mount Bracket without modification.

The detector[s] shall incorporate a three-color LED to indicate the different operating conditions. Red shall indicate an alarm condition. Green shall indicate a PIR activation. Yellow shall indicate a microwave activation. The LED shall be able to be field disabled using a jumper.

The detector[s] shall be capable of operating from a DC power source rated within the range of 9 to 15 volts DC, and shall draw a nominal 18 milli-amps (mA) over the rated voltage range.

A condition of alarm shall occur when both the PIR and microwave alarm conditions are met. The detector shall signal the condition of alarm using a Supervised Normally Closed Reed Relay with terminal strip connections.

To accomplish PIR detection, [each] [the] detector shall contain a sealed Pyro-Electric sensor peaked for the detection of near-infrared energy in the 10 micron region. Spike-Noise suppression circuitry shall inhibit alarms caused by noise burst signals. To guard against unwanted alarms caused by changes in infrared energy not associated with motion, the sensor shall utilize a balanced Dual-Opposed element.

The PIR detection shall use Motion Analyzer II Signal Processing. Motion Analyzer II is a highly advanced signal processing technique that shall require a specific signature and timing of signals to generate an alarm. The processor shall analyze the incoming signal and automatically adjust for target speed and signal strength

Motion Analyzer II Processing shall provide two sensitivity settings.

[Each] [The] detector shall contain a front mounted Fresnel lens which shall focus received infrared energy onto the sensor. The sensor and module combined shall then construct a protection coverage field of view consisting of a 90° wide Broad Coverage pattern with five (5) planes of protection. The top plane shall consist of eleven sensor zone-pairs angled 0° downward from the horizontal, and horizontally spaced at 0°, plus and minus 9°, plus and minus 18°, plus and minus 27°, plus and minus 36°, plus and minus 45 from center. The rated range of the top plane shall be [twenty feet (20 ft.)] [six meters (6 m)].

The second plane shall be angled 8° downward from the top plane, and shall consist of four sensor zone-pairs spaced at plus and minus 18° and plus and minus 36°, from center.

The third plane shall be angled 16° downward from the top plane, and shall consist of four sensor zone-pairs spaced at plus and minus 18° and plus and minus 36°, from center.

The forth plane shall be angled 29° downward from the top plane, and shall consist of two sensor zone-pairs spaced at plus and minus 18° from center.

The fifth plane shall be angled 75° downward from the top plane, and shall consist of a sensor zone-pair horizontally spaced at 0° from center.

The coverage pattern selected shall be horizontally adjustable up to plus and minus 10° from center, and vertically adjustable up to plus 2° and minus 10° from center.

To accomplish microwave detection, [each] [the] detector shall utilize an integrated DRO oscillator and strip-line antenna design. Using a precise pulse width and repetition frequency, the transmitter shall transmit pulses of microwave energy into the intended area of protection. Employing the Doppler Shift principle, the receiver shall monitor for any returned microwave energy at or near the transmitted frequency, and shall compare the received frequency to the transmitted frequency To guard against false activations, the microwave portion shall incorporate both adaptive Signal Processing and Pattern Recognition Technology. Pattern recognition circuitry shall identify and ignore repetitive false alarm sources. Adaptive Processing shall adjust to background disturbances. This shall help to reduce false activations while maintaining catch performance.

Free-space microwave coverage shall be a teardrop shaped pattern rated at [20 ft. long by 20 ft. wide] [6 m long by 6 m wide]. To suit the properties of each installation, the coverage shall be field adjustable by use of a built-in Microwave Range. To compliment the PIR technology, the microwave circuitry shall be designed to enhance cross-walk performance, and shall contain a filter for rejection of electrical noise signals generated by fluorescent lights. Pulse Modulation design shall permit multiple unit installation, and low current operation.

To ensure proper circuit operation, the detector[s] shall incorporate both a PIR self-test and Microwave self-test with defaults. The PIR circuitry shall be tested once every 12 hours by an internally generated electronic signal.

[Each] [The] detector shall include immunity to signals produced by pets and other small animals. This shall include immunity to one dog up to [100 pounds] [45 kg], or 2 dogs up to [60 pounds] [27 kg], or 10 cats, or any number of small rodents.

The Microwave shall perform a self-test every 12 hours by oscillating the transmitted signal and analyzing the received signal. If the microwave section fails, the detector[s] will default to PIR only operation. If this occurs, the detector[s] shall adjust the PIR sensitivity to standard.

If either supervision condition occurs, the detector[s] shall indicate the trouble condition by flashing the alarm LED continuously in a 4 pulse sequence .

[Each] [The] detector shall feature a single piece electronics board mounted to a base produced from the U.L. Component Recognized material ABS "Cycolac," Grade T or GSM, Rated 94HB, and shall be enclosed with a two-point, positive latch, snap-in-place cover of the same material. The front of the cover shall contain two (2) white-light opaque windows, one which shall be microwave transparent and one infrared transparent, with both constructed from U.L. Component Recognized materials. When combined, the total package shall not exceed [5 in. High, by 2.8 in. Wide, by 2.2 in. Deep] [12.7 cm High, by 7.1 cm Wide, by 5.6 cm Deep].

[Each] [The] detector shall be rated to operate within the temperature range of [minus 20° Fahrenheit to plus 120° Fahrenheit] [minus 29° Celsius to plus 49° Celsius].

The Dual Technology Intrusion Detector[s] shall be model DS820 [with optional Gimbal Mount Bracket B328] [or] [with optional Low Profile Swivel Bracket B335] [or] [with optional B800 Ceiling Mount].
