DS150i/DS151i Overview
The DS150i and DS151i are passive infrared detectors designed for request-to-exit (REX) applications. They detect motion, signaling access control systems. Available in light gray (DS150i) and black (DS151i).
Detector Models and Applications
The DS150i series encompasses two models⁚ the DS150i (light gray) and the DS151i (black). Both are specifically engineered for request-to-exit (REX) applications in access control systems. These detectors excel in identifying motion within their detection range, subsequently transmitting a signal to the access control system or door control mechanism. This triggers the release mechanism, granting access. Their primary application lies in facilitating effortless exit from secured areas, streamlining the egress process and improving overall security system efficiency. The DS150i and DS151i are designed for seamless integration into various access control setups, enhancing security protocols.
Motion Detection and Signaling
The DS150i and DS151i employ passive infrared (PIR) technology for motion detection. This technology senses changes in infrared radiation caused by moving objects within its field of view. Upon detecting motion, the detector triggers a signal, typically a relay closure, to communicate with the access control system. This signal indicates that motion has been detected within the monitored area, prompting the system to initiate the designated action, such as releasing a door lock or activating an alarm. The sensitivity and range of motion detection can be adjusted depending on the specific installation requirements. The speed of signal transmission is designed to be rapid and reliable to ensure immediate response to detected movement.
Key Features⁚ Activation LED
A prominent feature of both the DS150i and DS151i models is the externally visible activation LED. This LED provides clear visual confirmation of the detector’s operational status. When the detector senses motion and transmits a signal, the LED illuminates, offering immediate visual feedback. This visual cue is invaluable for troubleshooting purposes, allowing for quick confirmation of proper functionality and aiding in identifying potential issues. The bright LED is easily visible, even in low-light conditions, ensuring reliable visual indication regardless of ambient lighting. The inclusion of this LED significantly enhances the user-friendliness and ease of maintenance of these request-to-exit detectors.
Installation and Configuration
This section details mounting (ceiling or wall), wiring, adjustments, and solutions for double-door installations of the DS150i/DS151i.
Mounting Options⁚ Ceiling and Wall
The Bosch DS150i and DS151i detectors offer versatile mounting options to suit diverse installation needs. For ceiling mounting, ensure the unit is securely fastened to a stable surface, allowing for optimal coverage of the designated area. Proper alignment is crucial for effective motion detection; Wall mounting provides flexibility in placement, particularly in areas where ceiling mounting may be impractical or unsuitable. When wall mounting, consider the detector’s field of view to ensure it effectively covers the intended access point. Use the provided mounting hardware and follow the instructions carefully to ensure a secure and stable installation. Always check for obstructions that could interfere with the sensor’s performance after installation. Remember to consult the installation guide for detailed diagrams and specifications for both ceiling and wall mounting procedures.
Wiring and Adjustments
Correct wiring is essential for the DS150i/DS151i’s functionality. Connect the power supply according to the wiring diagram in the manual, ensuring correct polarity. The relay output allows for various configurations, enabling customization based on specific access control system requirements. Adjust the sensitivity settings to optimize performance in the given environment; higher sensitivity may lead to false triggers in areas with significant ambient movement, while lower sensitivity might miss legitimate requests. The timing of the relay can be adjusted to suit the door’s operation; a longer time may be needed for slower-acting doors. Always double-check all connections before powering the unit to prevent damage. Consult the technical specifications for detailed information on voltage, current, and other electrical parameters. Improper wiring could result in malfunction or damage to the detector, so carefully follow the instructions.
Addressing Double Door Issues
Double doors without a center post present a unique challenge for request-to-exit systems. The gap between the doors can cause issues with motion detection, potentially leading to false triggers or missed activations. To address this, strategic placement and aiming of the DS150i/DS151i detector is critical. Consider using masking techniques to block detection of the gap area while maintaining coverage of the doorway itself. Alternatively, two separate detectors might be necessary, each covering one door independently to ensure reliable operation. Proper placement minimizes the risk of interference between the two doors, preventing unwanted activations from movement in the gap. Careful planning and consideration of the physical layout are crucial for successful implementation with double doors.
Technical Specifications

For C-UL listed installations, the REX must be connected to ULCS319 compliant systems to ensure continued compliance.
Relay Output and Programming
The DS150i incorporates a relay output featuring two Form C contacts. These contacts offer versatility in controlling access control systems. A key feature is the adjustable latching time, ranging from approximately 0.25 seconds to 60 seconds. This allows customization to suit diverse access control needs and configurations. The relay’s functionality extends to power loss scenarios, offering programmable fail-safe or fail-secure modes. In fail-safe mode, the relay defaults to an open state during a power outage, while fail-secure mode maintains a closed state. This programming flexibility ensures the system’s behavior aligns with specific security protocols and requirements, enhancing overall security and operational reliability. The precise configuration depends on the specific application and system integration.
EMF Spike Protection
The DS150i/DS151i incorporates robust EMF (electromagnetic field) spike protection for its relay pins. This crucial feature safeguards the sensitive electronics from potentially damaging voltage surges. Pins 6, 7, and 8 (gray, green, and orange wires respectively) constitute the EMF spike-protected relay circuit. This protection is vital in environments where electrical noise or power fluctuations are common. Protecting the relay from these surges ensures reliable operation and prevents premature failure, extending the lifespan of the detector. The integrated protection enhances the overall system’s resilience and dependability, minimizing downtime caused by electrical disturbances. This is particularly important in industrial or high-interference settings where transient voltage spikes are more likely to occur.
