## Summary description

Curver AMLRMMW40WT is a wireless ultrasonic motion detector designed for ceiling or wall mounting. It features a narrow 10° detection angle, an 80 dB built-in alarm, and operates on three AAA batteries (4.5 V input). The compact, lightweight sensor (80 g) provides presence detection for entryways, corridors or small rooms and is suitable for battery-powered security or automation setups.

## Long description

Curver AMLRMMW40WT is a wireless ultrasonic motion detector designed for ceiling or wall mounting. The compact sensor uses ultrasonic technology with a narrow 10° detection angle and a detection distance of about 1.1 m to detect presence in entryways, corridors and small rooms. Powered by three AAA batteries (4.5 V), the unit includes an integrated 80 dB alarm and a mounting bracket that allows adjustment over more than 300° so the sensor can be angled for optimal coverage.
Advantages
The detector combines ultrasonic sensing and a built-in 80 dB alert into a single battery-powered unit that does not require a separate receiver. Its narrow detection cone and short detection distance make it suitable for targeted monitoring where limited coverage is needed. Lightweight construction and the adjustable mounting bracket simplify installation on either a wall or a ceiling, and the wireless design eliminates the need for wiring.
Suitable for
Securing entrances and short corridors
Presence detection in small rooms or closets
Battery-powered security or automation setups
Applications requiring a narrow, directional detection zone
Key specifications
Detection technology: Ultrasonic sensor
Detection angle: 10°
Detection distance: approximately 1.1 m
Alarm output: integrated 80 dB siren
Power supply: three AAA batteries (4.5 V input)
Mounting: ceiling or wall with adjustable bracket (over 300° adjustment)
Weight: approximately 80 g
Color: white
How to use
Install three AAA batteries in the battery compartment according to the polarity markings. Mount the detector on a wall or ceiling using the supplied bracket and adjust the angle to align the 10° sensing cone toward the area to be monitored. After installation, test the sensor by walking through the detection zone at the intended distance to confirm reliable triggering and audible alarm operation. Replace batteries when the detector shows reduced sensitivity or when alarm volume declines.
Usage recommendations
Place the sensor so its narrow detection cone points directly at the intended coverage area; avoid locating it where reflective surfaces or large obstructions can interfere with ultrasonic waves. For battery-powered operation, use fresh AAA batteries and check them periodically. Keep the sensor away from strong airflow or vibrating surfaces that could cause false triggers.
