4 SAFE

The 4SAFE is a failsafe active infrared safety sensor designed to protect users from contact with moving swing and revolving doors. By using distance‑measuring infrared technology, it creates a three‑dimensional safety zone that detects people before any contact with the door can occur.

Features

High User Safety

The 4SAFE sensor ensures reliable protection for all door users. Its advanced active infrared technology creates a 40 cm detection zone in front of the door leaf at a 2 m mounting height, using 4 groups of 2 infrared spots. This early detection prevents contact with moving swing or revolving doors, enhancing safety for all, including people with reduced mobility.

Easy Installation

Setup is fast and intuitive: A single push button automatically configures the sensor for standard installation heights.

4 DIP switches allow quick fine‑tuning for precise adjustments. This makes installation efficient for technicians and ensures optimal performance in any environment.

Adaptation to All Floor Types

The 4SAFE is engineered to perform reliably on all floor surfaces, even highly reflective or challenging ones, such as:

• Stainless steel plates
• Metal grids
• Water puddles
• Snow‑covered ground

Its intelligent background‑suppression technology ensures stable detection regardless of contrast or surface conditions.

Easy Daisy‑Chain Mounting

For wider doors or complex installations, the 4SAFE supports daisy‑chain mounting of up to 6 modules. This allows seamless coverage across the entire door width while keeping wiring simple and installation clean.
