5. Presentation Overview
In this presentation we will review the following main topics
Physical construction
Patented animal immunity
Other DG85W features
Advanced digital detection system
Installation recommendations

6. Physical Construction

7. Weatherproofing Resists water, snow, wind, dust and insects
Injected Rubber Gasket
A special rubber gasket is injected into the casing to effectively isolate the unit on all sides
Unique in the industry
Second rubber gasket
Another rubber gasket is placed around the lens's mask for additional weatherproofing
Plastic PCB cover
Protects important part of electronic circuit on both sides of PC board
Rubber foam
Seals the wire entry

8. Impact and Temperature Resistant
Casing made from ABS & polycarbonate
Combining these two plastic materials makes the casing much harder and therefore more resistant to impact and extreme temperatures
Withstands temperatures as low as -35C (-31F)
The DG85W continued to perform extremely well in our Canadian winters
Withstands temperatures as high as 50C (122F)
This specification must be respected
Recessed lens with protective mask
Reduces the probability of damage from objects that can harm the lens (e.g. ball or machinery)

9. Lens Material
Special Poly IR 9 material with a thickness of 0.5mm (0.02in) provides:
Additional UV protection
Resistance to discoloration and deterioration
A surface that repels dirt and is easier to clean

10. Dual Optical Filtering System
Additional special filters for both sensors
Blocks out visible light (e.g. sunlight or car headlights)
Allows only infrared light to pass through (e.g. body heat)

11. Unique Bezel Design
The sensors pass through the bezel opening, completely isolating them from the area where air or insects may be able to enter (i.e. screw or wire entry)

12. Colour Why did we choose this colour?
Lowers the internal temperature of the detector
Because it looks great!

13. DG85 Series
DG85W – Standard lens

14. DG85W Why Animal Immunity?
In outdoor applications, animal immunity is vital
Pets, roaming animals, birds and rodents pose a potential risk for false alarms
Outdoor motion detectors must be able to differentiate between animals and humans

15. DG85W Patented Animal Immunity
DG85W is immune to one pet weighing up to 40kg (90lbs)
This is accomplished using:
Patented Digital Motion Detection
Two dual-opposed infrared sensors
A specially designed lens pattern
We will discuss this technology in the following slides

16. DG85W Two Dual Opposed Infrared Sensors
The upper and lower sensor are opposed
The human body generates an equally positive and negative signal pattern

17. DG85W Two Dual Opposed Infrared Sensors
Unlike a human body, an animal does not generate an equally positive/negative signal pattern
Generally one sensor generates a stronger signal than the other
DG85W detection

18. DG85W Specially Designed Lens
Beams from the upper and lower sensor are interlaced to ensure better coverage
Generates 64 coverage zones compared to 14 zones with the Optex VX-402.

19. DG85 Series
DG85W – Standard lens
DG85L1 – Pet Alley lens

20. DG85L1
Comes equipped with a Pet Alley lens especially designed to allow large-breed dogs as well as multiple pets to roam freely
Reduces false alarms caused by high infrared signatures

21. DG85L1
Specially-developed Pet Alley lens creates a safe zone near ground level
Large dogs and multiple pets remain undetected below the 1.1m (3.6ft) detection level

22. DG85 Series DG85W – Standard lens DG85L1 – Pet Alley lens
DG85L2 – Curtain-1 lens

23. DG85L2 Comes equipped with the Curtain-1 lens
Creates a curtain barrier especially designed to protect vertical surfaces

24. Other DG85W Features

25. Two Operational Modes DGP2 Mode (addressable)
Connects directly to a Digiplex (DGP-848 or DGP-NE96) 4-wire combus
Communicates its alarm and tamper signals, data and settings via the combus
In this mode, the relay remains active and can be used to activate other devices
Relay Mode (conventional)
Functions like any conventional motion detector
Communicates its alarm and tamper signals via relays

26. Adjustable Sensitivity
Multi-level
11 sensitivity settings
Other detectors, like the Optex VX-402 have only three levels
Remote adjustment
Unique in the industry
Adjust settings remotely using a keypad or the WinLoad software
Can also be adjusted locally

27. Metal Shield Metal shield covers parts of electronic circuit
Maximizes protection from electromagnetic and radio frequency interference

28. Advanced Digital Detection System

29. Patented Digital Detection
An industry first
Completely software driven, this technology converts, amplifies and processes the sensor’s low-level signal digitally without any analog circuitry.
Processes the sensors’ entire signal without any saturation or noise
Provides increased accuracy, reliability and superior false alarm immunity

30. Dual Opposed Detection
Compares the entry and exit signals’ polarity
Only movement signals generate opposed polarity signals, which are processed by the software
Interference signals generate same-polarity signals, which are rejected by the software

31. Dual Opposed Detection

32. Patented Digital Auto Pulse Signal Processing
Measures energy from each detected signal and stores them in memory
To generate an alarm, the memory must reach the required minimum level:
With high-level signals (low risk of false alarms), the detector generates an alarm, functioning as a "non-pulse count" detector
With low-level signals (high risk of false alarms), the detector switches to a very high pulse count mode–resulting in excellent protection against false alarms

33. Patented Digital Auto Pulse Signal Processing

34. Digital Dual Edge Processing
Separates the entry and exit signals
The entry signal and the exit signal must reach their respective levels, otherwise an alarm is not generated.
As a result, false alarm immunity is dramatically increased.

35. Digital Shield Algorithm
Real Time DSP (Digital Signal Processing)
Digitally amplifies and filters the sensor signal in real time
Digital filters are accurate and don’t add cost or hardware components
Movement Analysis
Measures and calculates the signal’s parameters in real time and then stores them in memory
Compares each signal with a reference bank and if the signal does not meet movement criteria, it is rejected
RFI/EMI Protection
Effectively records high-level RF signals without clipping or distortion
Recognizes RFI/EMI conditions and effectively distinguishes between interference signals and movement signals

36. Digital Automatic Temperature Compensation
Automatically adjusts the motion detector’s sensitivity according to the difference between the room temperature and body temperature

37. Installation Recommendations

38. Detector Height Adjustment
Ensure that the adjustable measurements marked on the PCB (inside the unit) match the installation height
Installation height is measured from the center of the detector
PCB adjustments should be followed by a walk-test
DG85W
2.1m (7ft)
DG85L1
1.1m (3.6ft)
DG85L2

39. PCB Height Adjustment
DG85W and DG85L2 only

40. Across Detection Pattern
Mount detector so that traffic flows across the detection pattern
Remember that a passive infrared motion detector is not as effective when a person or animal moves towards the detector
Therefore avoid installing it over a door
Install it so that intruder movement is perpendicular or diagonal to the beams

41. Limit Contact with Outdoor Elements
Avoid direct contact with outdoor elements
It is designed to resist the elements to prevent damage to the detector
But some elements can still reduce motion detector effectiveness
For example, if the lens is wet, visibility will be somewhat reduced, much like when your car's windshield is wet
Avoid installing the detector where strong sunlight could shine directly onto the sensors

42. Avoid Moving Objects
Avoid pointing the sensors towards moving objects or reflective surfaces
Clothes hanging on a line, flags, trees or vehicles
