DOR-O-MATIC 96890-900 Safety Beam System
The DOR-O-MATIC 96890-900 Safety Beam System is an active infrared safety solution designed to enhance pedestrian protection in automatic door applications. Engineered to meet evolving safety requirements, the system utilizes microprocessed infrared technology to detect the presence of people and objects within the doorway, helping prevent unsafe door movement.
Its compact design allows for discreet installation within door frames while providing reliable performance in demanding commercial environments.
Key Features
- Active infrared presence detection
- Microprocessed control technology
- Compact, concealed installation
- Single-beam or dual-beam operation
- Adjustable detection range
- Fast response time
- Weather-resistant NEMA 4 enclosure
- Compatible with automatic sliding and swing door systems
- Normally Open (NO) and Normally Closed (NC) relay outputs
How It Works
The 96890-900 Safety Beam System creates an invisible infrared barrier across the door opening. When the beam is interrupted by a person or object, the control board sends a signal to the door operator, preventing unsafe movement or initiating a safety response.
Detection Method
- Presence sensing through beam interruption
- Single or crossed beam configurations
- Continuous monitoring during door operation
