Outdoor Intelligent Wireless
Detector With 2 PIR
Installation Guide

General Introduction On Outdoor Application

This detector is remarkable in function, but the following notices can make it more stable if installer can pay attention to them:
WEEDS
High weeds and shrubbery in detection range may wave in wind and cause false alarm, especially for those detectors operating in horizontal fan area, so keep cutting on weeds and shrubbery.
RAIN
Sudden rainstorm can cool the hot pitch road or surface of other roads quickly. And all detectors can detect rain in the sky, but detector with down view window can even detect water on ground, which will bring much more interference to detectors outdoor than that mounted on wall, so everything will lower its temperature similar to water, human body or cars after pouring from rain can offer very little temperature gap for detection, so sensitivity will be lowered a lot.
INSECTS
Insects will trigger false alarm when they climb into detector or stay on lens, while those staying away from detectors can’t trigger alarm. If there is interference from insects, please re-install detector or use insecticide. And please adopts strictly sealed components on those drilled holes or glass glue around detector.
CAR
Moving car in detection range may trigger false alarm to detector.
INSUFFICUENT TEMPERATURE DIFFERENCE
Detector is sensitive to change from temperature difference in detection area, if target temperature is very close to previous environment temperature, there will be no temperature change, detector sensitivity will be lowered and will not be triggered sometimes when there is intrusion.
DIRT ON LENS
Lens becomes easily dirty when used outdoor, so please check the lens from time to time in order to avoid alarm miss caused by low sensitivity from dirty lens.
UNSTABLE INSTALLATION BASE
Detector will trigger false alarm easily if installation base can be interfered by vibration, this is the reason why some detectors installed near to street can cause false alarm easily.

INTRODUCTION

The detector is a dual pir outdoor wireless detector with intelligent solar charge technology;it can match most of the wireless control panels directly and all wired control panels by wireless-to-wired receiver (REC-4CH). This detector adopts intelligent multigrade digital recognition technology and unique SLT calculation to process the 2-way special pir signal and 1 way environmental temperature signal to reach the topgallant detection and lowest false and missing alarm. It can recognize waving object and real human motion; resist direct or reflective sunshine and accomodate the false alarm caused by speedy hot and cool air. The detector can operate in outdoor severe environment for long term. 8 bands of sensitivities for option, can take on the weather difference caused by rain, snow, hail, strong sunshine, gale etc, it is a purely high-class outdoor detector worthy of selection and usage.

INSTALLATION GUIDE

Even though Detector can accommodate outdoor severe environments, the following factors shall be avoided during install-ation in order to get the reasonable detection:

|
---|---
No direct facing cold/hot source| Mount on a secure and stable base/object
|
Incorrect Installation (with pet immunity lens)| Place without enough sunshine such as eave and umbrage etc
|
electrical interferences Keep away from strong| Keep away from high pressure power
|
Don’t install on a tree| Avoid moving vehicles

On installation angle
Detection is with mechanical difference to intrusion angles

On installation position

On installation height
Recommended installation height is 1.8-2.4m

BRACKET INSTALLATION AND DIRECT INSTALLATION (FOR OPTION)

In order to get the maximum detection range, please install detector at 2.1m height and adjust PCB position to “0” mark vertically. However, detector can be installed at 4m superlatively.
Please guarantee that there is no source of interference nearby and the front view of detector is wide and clear.

1. Drill a hole on wall and insert the rubber stopper into the hole, fasten the detector by 3 screws.
2. Open the front cover: release the bottom screw anticlockwise by a plus-screw-driver(no need to twist out from cover), lift out the cover from bottom and then turn on the power switch, red LED will flash for 40 seconds as warm-up, when LED stops, walking test can be performed. (Please refer to following content on other setting). Then, close the cover as figure and tighten the screw. (Refer to below figure for details)
3. Decomposingsteps

Note : please wear on the rubber ring for water proof before fastening detector onto the wall. Or water might go into detector and cause damage .

The 12V power supply connection

Note: please do lead cable according to above instruction, don’t drill holes to lead cable on top/back/side of detector, otherwise it will damage the water-proof structure and cause false alarm or malfunction.
Connect external 12VDC power to detector as figure, lead the power cable from bottom power-lead slot and seal the cable-lead hole by silicone sealant in order to avoid water and insects go into detector, then connect power cable to relevant terminals (Care for the polarities)

Warning : this terminal can only be connected by 9-16V DC power, illegal higher voltage will cause permanent destroy to detector.

PCB LAYOUT AND WIRELESS CODING

ID registration (coding with alarm control panels)
You can match detector with control panel before installation. When control panel enters into learning status, you can press down STUDY button to trigger detector and register its ID into control panel.

Setting of compliance with other control panels Oscillation resistor set:
Compliance with other control panels can be reached through regulation of oscillation resistance on encoding chips. Refer to left figure, our oscillation resistance is with 3 modes:

PT2262 protocol: 4.7M、3.3M、1.5M
EV1527 protocol: 430K、330K、100K
Data set: Proper coding data can be obtained by “DATA SET” pins for control panel recognition: 1=D3;2=D2; 3=D1;4=D0 (Codes under some special protocols might be inverse)

DIP SWITCH SETTING

Dip switch 1: (sensitivity control)
When dip switch 1 is set to OFFdetector is in high sensitivity mode.
When dip switch 1 is set to ON, detector is in low sensitivity mode.

Dip switch 2: (Setting on PIR pulse detection) When dip switch 2 is set to OFF, detector is in 2 pulses mode.
When dip switch 2 is set to ON, detector is in 3 pulses mode.
Signal processing statement: this detector adopts digital direct signal- analysis technology, digital processing CHIP will analyze those signals detected by sensors in frequencies, scope, polarity etc, and make comparison with those usual pet- data in data base and draw real conclusion on body intrusion. So, here, pulse setting is just a general index, might not be actual pulse quantity during signal processing.

When set to 2 pulse counting, detector is in high sensitivity, detection of 2 intrusion pulses may cause alarm usually.
When set to 3 pulse counting, detector is in low sensitivity, alarm will be triggered only when 3 intrusion pulses are detected.

Dip switch 3: ( mode selection)
When dip switch 3 is set to OFF, detector is in USE mode.
When dip switch 3 is set to ON, detector is in TEST mode.
DIP4 LED control
When it is “OFF”LED is turn off to reach the purpose of energy saving and concealed installation.
When it is “ON”, LED is turn on.
Note: after installation and walking test finished, dip switch 3 and 4 should be set to OFF mode in order to extent battery life!

VERTICAL ADJUST

Adjustment can be made through the moving of PCB up and down as the left figure in order to reach the best detection

WALK TEST

Preparation： before test, please do set dip switch 3 & 4 to ON position and choose proper sensitivity and pulse counts acccording to installation environment and detction requirement, in order that detector can obtain best operation.
Close the front cap, when LED indication is off, perform a transverse movement to check the PIR performance through the red LED, this can avoid the dead angle of PIR detection. PIR is in highest sensitivity when movement is transverse to the detector.

NOTES AND WARNINGS

Even the most sophisticated detectors can sometimes be defeated or may fail to activate due to: DC power failure/improper connection, malicious masking of the lens, tampering with the optical system, decreased sensitivity in ambient temperatures near that of the human body and unexpected failure of a component or circuit. The above list includes the most common reasons for failure and it is recommended that the detector and the entire alarm system be checked weekly to ensure proper performance.
An alarm system should not be regarded as a substitute for insurance. Home & property owners or renters should be prudent enough to continue insuring their lives & property even though they are protected by an alarm system.
