Secrui PR3 Motion Sensor Alarm Motion Detector
PARTS IDENTIFICATION
Product Introduction
This host is a passive infrared detector. It uses digital dual-core fuzzy logic infrared control processing technology and an intelligent analysis algorithm, which can effectively distinguish the interference signal and the human motion signal to prevent false alarms. This host can connect the remote control, and the performance is suitable and reliable. It is suitable for large villas, office buildings, clubs, leisure centers, hotels, families, and sandhops. Etc.
Package
- PIR Alarm unit(s)
- Remote control(s)
- Warranty card
- AAA alkaline batteries
Feature
5 tunes optional.
4 levels of adjustable volume.
The remote control can control all the functions.
Operating Instructions
PIR Alarm Unit Setting
Setting
- Short press < 2s shift Arm and Disarm, beep once means Arm, beeps twice means Disarm.
- Long press >5s from on to off, it will beep once, from off to on, it will beep once continuously.
Setting (Tone)
Short press: Choose a different ringtone.
Setting (Volume)
Short press: Change volume cycle adjustment.
NOTE: When the host broadcasts the voice, even if you trigger any button on the host, the host state does not change.
Remote Control Setting
Switch on/off to control the PIR alarm power.
Press this button, the host will be alarmed.
When it reaches Maximum volume and minimum volume, the PIR detector will beep twice.
Shift Arm and Disarm, Beeps once means Arm, Beeps twice means Disarm.
Factory Settings
Plug and long-press [tone] and [volume] buttons until it beeps once, it will turn to the first tune and the biggest volume.
Low Power Prompt
- When the voltage is lower than a certain value, the button on the host or the remote control is triggered, the indicator light flashes 3 times, and there is no voice prompt; it indicates that you should change the battery or plug in USB power.
- When the battery voltage is too low, it will shut down automatically.
Attention
- Please use an Alkaline or rechargeable battery; do not mix the new and old batteries to use
- Non-professionals are not allowed to repair.
- Do not install the product in a place where it is exposed to rain, long periods of direct sunlight, or where the temperature will change rapidly.
Technical Parameters
- Working voltage: USB 5V or 3*AAA Alkaline battery.
- Standby current: <300uA.
- Working current: <100mA.

Secrui PR3 Motion Sensor Alarm Motion Detector-FAQs
What triggers the Secrui PR3 motion sensor?
The motion sensor activates when it detects movement, such as body heat or reflected microwave signals from a moving object. This triggers connected alarms or other security devices.
How does the motion detection technology work?
The Secrui PR3 uses Doppler radar principles, emitting microwave signals and detecting frequency changes caused by motion—similar to how a radar speed gun works.
What is motion detection mode?
Motion detection mode refers to the sensor’s ability to detect physical movement or sudden acceleration using a built-in G-sensor or accelerometer.
Can the sensor detect motion in the dark?
Yes, the sensor works in complete darkness. It detects movement through infrared heat or microwave reflection, not relying on visible light.
What is a motion detection alarm switch?
This refers to PIR (Passive Infrared) sensors that detect infrared energy (body heat) and movement. When rapid changes occur, such as someone passing through its field, it activates the alarm.
Where should I install the motion sensor alarm?
Install the sensor near common entry points like front doors, side doors, back doors, or ground-level windows—areas most likely to be accessed by intruders.
Does the motion sensor require Wi-Fi?
Wireless versions may use Wi-Fi or cellular networks to communicate with your security system. Wired versions may rely on landlines or Ethernet.
How can I adjust the sensor light timing?
To change how long the light stays on after detecting motion, locate the time delay dial. Turning it clockwise increases the time; counterclockwise decreases it.
