Bosch Request-to-exit Sensor DS150i/DS151i for REX Applications

The Bosch DS150i and DS151i are purpose-built motion detectors engineered for Request-to-exit (REX) environments. Designed to enable secure, hands-free egress, these sensors detect motion within their coverage area and instantly signal an access control system or door control device. Available in two distinct finishes to blend with your interior design—the DS150i in light gray and the DS151i in black—these detectors deliver Bosch-grade reliability in a compact, unobtrusive package. Ideal for commercial offices, retail spaces, healthcare facilities, schools, and other high-traffic settings, the DS150i/DS151i simplify door operation while maintaining stringent security standards. These sensors are built to integrate with Bosch access control ecosystems and are compatible with a range of controllers, providing flexible deployment without compromising performance. With straightforward installation, dependable sensing, and a design that respects aesthetics as well as safety, the DS150i/DS151i help you create safer, more efficient occupancy and egress flows for both customers and staff.

• Designed specifically for Request-to-exit (REX) applications, the Bosch DS150i/DS151i provide reliable, hands-free egress by detecting motion in their coverage area and signaling the connected door or access control system for immediate release.
• Two color options—DS150i in light gray and DS151i in black—allow technicians to select the finish that best harmonizes with the environment, mounting surfaces, and architectural style for a clean, professional installation.
• Seamless integration with access control systems: when motion is detected, the sensor communicates with the door controller or access panel to permit secure, controlled exit, reducing delays in high-traffic doors and minimizing user friction.
• Compact, low-profile form factor designed for mounting near doorways, corridors, or vestibules without obstructing traffic or compromising interior design, while delivering dependable performance in busy environments.
• Durable construction and Bosch-quality sensing technology provide consistent performance in a variety of lighting and environmental conditions, helping to minimize false releases and maintain smooth egress in daily operations.

Technical Details of Bosch Request-to-exit Sensor

• Models: DS150i (light gray) and DS151i (black) — two finish options within the same REX sensor family.
• Function: Motion-based detector that signals an access control system or door control device to enable hands-free exit when movement is detected.
• Intended use: Specifically configured for Request-to-exit (REX) applications in commercial environments, including offices, retail spaces, and public facilities.
• Form factor: Compact, discreet housing designed for mounting near doorways while preserving interior aesthetics and visitor flow.

how to install Bosch Request-to-exit Sensor

• Plan placement: Identify a suitable mounting location near the door that provides a clear line of sight to typical exit paths. Position the sensor so that pedestrian movement naturally passes through its coverage area without being obstructed by decorations, signage, or fixtures.
• Power and wiring: Connect the sensor to the appropriate low-voltage power supply and wiring required by your access control system or door controller. Follow the wiring diagram in the official installation instructions to ensure correct signal output and safety compliance.
• Mounting and alignment: Secure the DS150i or DS151i to its mounting surface using the supplied hardware. Verify alignment so that the sensor’s field of view captures exiting traffic while avoiding exposure to glare or radiant heat sources that could affect performance.
• Configure sensitivity and timing: Adjust any available sensitivity, delay, or hold-open settings to balance quick release with protection against false triggers. Test in typical operating conditions to ensure consistent performance across peak and off-peak periods.
• System integration and testing: Connect the sensor to the door controller or access control panel. Conduct thorough tests of real-world exit scenarios, confirming that motion triggers a timely, reliable door release and that the system returns to a secure state after egress completes.
• Safety and compliance: Confirm installation complies with local electrical codes and facility safety requirements. Document the installation with diagrams and keep manufacturer guidelines handy for maintenance or future upgrades.

Frequently asked questions

• What is the Bosch Request-to-exit Sensor? The Bosch DS150i and DS151i are motion-detection devices designed to support REX operations. They sense movement in their coverage area and signal a connected access control system or door controller to release a door, enabling secure, hands-free egress.
• What are the differences between DS150i and DS151i? The primary distinction is finish: DS150i is light gray, while DS151i is black. Functionally, they perform the same REX sensing tasks; selection is based on aesthetic and placement considerations.
• How do DS150i/DS151i integrate with access control systems? When motion is detected within their coverage, the sensors send a signal to the associated door controller or access control panel, triggering a controlled release. Compatibility with Bosch ecosystems can simplify wiring and configuration, while third-party integrations may vary by system.
• Can these sensors be installed in high-traffic areas? Yes. The DS150i/DS151i are designed to support reliable egress in commercial environments with frequent door usage. Proper placement, alignment, and sensitivity settings help optimize performance in busy corridors and entrances.
• What should I consider during installation? Focus on mounting location, unobstructed coverage, appropriate power supply, and correct wiring to the door controller or access control system. After installation, perform comprehensive testing to ensure consistent operation and adjust settings as needed.
