Wall-mounted motion sensor Virone MS-1 — passive infrared occupancy detector, basic model

Virone MS-1 is a wall-mounted motion sensor that uses passive infrared (PIR) technology to detect human presence and movement. The MS-1 is a basic occupancy detector intended for automatic switching of lighting or alarm inputs when motion is detected. Its compact design and straightforward functionality make it suitable for corridors, entrances, stairways and small rooms where simple motion-triggered control is required.

Advantages

The MS-1 provides reliable passive infrared detection with low power consumption and a minimal visual footprint on the wall. It offers quick detection of movement and straightforward integration into lighting or alarm circuits without complex configuration. The device is designed for easy installation and maintenance, providing consistent occupancy detection for basic automation tasks.

Suitable for

• Corridors and hallways
• Entrance areas and foyers
• Stairwells and landings
• Small offices, storage rooms and utility spaces
• Basic lighting control and alarm activation

Key specifications

• Detection technology: passive infrared (PIR)
• Mounting: wall-mounted
• Primary function: occupancy and motion detection
• Typical applications: automatic lighting switching, alarm input triggering
• Design: compact, low-profile enclosure suitable for indoor use

How to use

Mount the Virone MS-1 on a stable wall surface at the recommended installation height for optimal coverage and connect it to the corresponding lighting or alarm circuit following the electrical guidelines of the facility. Once powered and wired, the sensor monitors the protected area for heat changes caused by human movement and closes or opens its output to trigger lights or alarm inputs when motion is detected. No advanced user configuration is required for basic operation; adjustment of placement and orientation ensures the intended coverage pattern.

Usage recommendations

Install the sensor at the manufacturer’s recommended height and away from direct heat sources, air vents, or reflective surfaces to reduce false triggers. For best results in corridors and stairwells, position the sensor to cover the main walking path and avoid mounting opposite large windows where sunlight could affect detection.
