Active infrared barrier SATEL ACTIVA-6 (model 9124) — 6 m detection range, active IR curtain

SATEL ACTIVA-6 (model 9124) is an active infrared barrier designed to provide reliable short-range perimeter protection and access control. The device generates an infrared curtain with a 6 m detection range to sense passage through gates, doorways, narrow corridors or along fence lines. Compact and intended for integration with alarm control panels, the ACTIVA-6 is suitable for installations where accurate intrusion detection in a confined area is required.

Advantages

The ACTIVA-6 offers precise detection in a compact housing and a defined 6 m sensing zone that reduces false alarms from distant movement. Its active infrared curtain design enables detection of objects crossing the protected plane, making it effective for controlling access through gates and openings. The unit is built for straightforward integration with standard alarm systems and supports reliable operation in typical outdoor or indoor perimeter locations when mounted and aligned correctly.

Suitable for

• Gate and driveway access control
• Fence line intrusion detection
• Doorway and passageway monitoring
• Perimeter protection for small yards and service areas

Key specifications

• Detection principle: active infrared curtain
• Maximum detection range: 6 m
• Detection plane: single-beam curtain for crossing detection
• Intended installation: surface-mounted on gates, posts or walls
• Integration: designed for connection to alarm control panels and access systems
• Form factor: compact housing suitable for limited-space mounting

How to use

Install the SATEL ACTIVA-6 so the infrared emitter and detector are aligned across the area to be protected, creating a perpendicular curtain to the expected direction of passage. Position the units at an appropriate height and distance to cover the desired 6 m zone and avoid obstructions that could block the infrared beam. Connect the detector to the alarm panel or access control interface following manufacturer wiring diagrams and configure input zones and alarm responses within the control system. Perform alignment and functional tests after installation to verify reliable detection and to adjust sensitivity or teaching procedures if the control panel supports them.

Usage recommendations

For best performance, mount the units on stable supports, ensure unobstructed line of sight between emitter and receiver, and protect the devices from direct mechanical impact. Regularly check alignment and cleanliness of optical surfaces and verify integration with the alarm panel during maintenance intervals. When used outdoors, follow mounting height and orientation guidance to minimise false triggers from small animals or vegetation moving across the beam.
