Products real shot:

Main Specifications
Scope of detection: 3-5 meters away, 105 degrees angle
Working voltage: DC 4.5 (AA AA battery: 3PCS (excluding customer's own configuration when using))

Alarm level: 105DB (decibel)

Installation requirements:

 ◆Since the infrared warning device has high infrared detection sensitivity when the human body moves laterally relative to the lens, but poor sensitivity for longitudinal movement, attention should be paid to the angle and height of the horizontal plane of the detector when installing, which has a great impact on the protection area.

◆ Installation should avoid the infrared policeware near the cold and heat sources, such as hot and cold air outlets, air -conditioning air outlets, electric heaters, cold fan, etc. to avoid straight -to -door.

◆ Remote -controlled infrared clerks should be directly seen by the scope of protection, and there must be no obstacles.

◆ The remote control infrared clerk should be a 10-30 degree angle with the wall surface. At this time, the detection distance should be far. The installation angle is adjusted according to the situation during the actual installation.

Instructions:

1. The infrared warning device has a standby delay of 20 seconds after it is first turned on. If the alarm signal is not detected within 20 seconds, you must leave the detection area of ​​the electronic dog within these 20 seconds.

2. If someone enters the detection area of ​​the infrared alarm after 20 seconds, the infrared alarm will delay for 5 seconds to facilitate the identification of the owner. After 5 seconds, if the correct password input is not received, a harsh alarm sound will be emitted for 30 seconds, and the alarm volume is 105 DB.5 seconds after the alarm sounds, if another person touches the infrared alarm, it will alarm again, and the cycle starts again.

3. When the infrared alarm alarms, you can enter the correct password to end the alarm.

Things to note:
1.It is recommended that you regularly check whether the infrared police officer work is normal to avoid leakage alarm.
2.When the booting indicator is dark, the alarm sound becomes small, and the infrared demonstrations have a high misunderstanding rate, the battery voltage is generally insufficient. At this time, the battery should be replaced in time.
