Description
Infrared sensor is kind of detecting element. It is usually made of high thermoelectric coefficient materials, such as lead zirconate titanate ceramics, lithium tantalite and triglycine sulfate. Pyroelectric sensor is composed of sensing detection element, interference filter and field-effect tube matcher. Pyroelectric infrared sensor generates no radiation. It features low power consumption, good concealment and low price. Pyroelectric sensor can only be installed indoors

Features
1. Such Infrared sensor features low noise and high responsibility.
2. Pyroelectric sensor adopts superior common-mode balance—double element type.
3. Pyroelectric infrared sensor employs TO-39 and TO-5 packaging.
4. Various filter windows are available for broad-band or narrow-band.
5. Single or twin channel parts and components are mounted in such infrared sensor.
6. Dual element or quad element components are used for anti-theft product. And single element components are applied for band thermal compensation.
7. Pyroelectric sensor features good anti-interference performance.
(1) Anti-interference from small animals. Pyroelectric infrared sensor installed within the recommended height will not alarm for small animals within detection zone.
(2) Anti-electromagnetic interference. It conforms to No. 4.6.1 requirements in GB10408. Mobile phone electromagnetic interference cannot cause false alarm.
(3) Anti-light interference. Radiated by H4 halogen lamp through glass window three meters away, such infrared sensor will not cause alarm within normal sensitivity scope.

Attention
1. Pyroelectric sensor should avoid direct radiation from sunlight, dazzle lamp and incandescent light.
2. It cannot face towards heat source (like heating radiator and heater, etc) so as to avoid false alarm due to temperature changes.
3. Infrared sensor must be installed with fastness in order to avert false alarm due to wind shake.
4. Don’t touch the surface of pyroelectric sensor.
5. Optical lens surface should be cleaned regularly with wet soft cloth or cotton so as to avoid dust interference.
6. Installation height is 2 m.
7. The circuit board has been debugged in factory, keeping detecting distance above 6 m. If there is something wrong with the whole alarm system, do not adjust or modify this circuit board, or the detecting distance cannot be guaranteed.

Correct Installation Requirements
1. Such infrared sensor should be 2.0 m to 2.2 m from the ground.
2. Pyroelectric sensor should be kept away from air conditioners, refrigerators and stoves, etc.
3. Shield, furniture, large bonsai and other partition should not be placed within the detecting zone.
4. Pyroelectric infrared sensor should not face straightly to the window, or hot air outside the window and people walking around will cause false alarm. Besides, it should not installed in places with strong current.
