Proper coding data can be obtained by “DATA SET” 
pins for control panel recognition: 1=D3;2=D2;

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

EV1527 protocol: 430K

330K

DIP SWITCH SETTING

Dip switch 1: (sensitivity control)
When dip switch 1 is set to OFF, 
detector 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.

Fast detection on target

Better way to avoid
false alarm

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.

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.

WARNING!

 Changes or modifications to this unit not expressly approved by the party responsible for compliance could 

void the warranty. This device has been tested and found to comply with the limits for a Class B digital device, pursuant 
harmful interference in residential installations. This equipment generates and  uses or radiates radio frequency energy 
and if not installed and used in accordance with the instructions, may cause harmful interference to radio and television 
reception. There is no guarantee that interference will not occur in a particular installation. If this device does cause such 
interference, which can be verified by turning the device off and on, the user is encouraged to eliminate the interference 
by one or more ofthe following measures:
- Increase the distance between the detector and the electrical/electronic equipment.
- Connect the device to a different power socket which supplies power to the detector.
- Consult the dealer or an experienced radio/TV technician

NOTES AND WARNINGS

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!

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.
