Bosch Request-to-Exit Sensor, Sounder

The Bosch DS160 Series Request-to-Exit (REX) sensors deliver a reliable, audible, and highly configurable solution for controlled door egress in busy environments. Available as the DS160 (light gray) and DS161 (black), these detectors are purpose-built for REX applications, providing precise timing, door monitoring, and targeted sensing that helps you manage access, security, and pedestrian flow with confidence. Whether you’re outfitting corporate offices, healthcare facilities, educational campuses, or retail locations, the DS160/DS161 sensors combine Bosch engineering with practical features like timers, door monitor with sounder alerts, and point-able coverage to meet demanding security requirements while preserving smooth egress for authorized users.

• Designed for reliable Request-to-Exit (REX) operation — The DS160 and DS161 are purpose-built to support secure, non-contact exit control. They deliver consistent door release upon valid egress while minimizing nuisance activations. Timers let you tailor the duration of the door release to suit foot traffic and door hardware, reducing wear on door mechanisms and ensuring a predictable exit period for occupants. The integrated door monitor continuously tracks door status, immediately signaling if a door fails to close properly, which helps close security gaps and discourage tailgating in high-traffic corridors.
• Versatile, color-coded designs for easy integration — The DS160’s light gray finish and the DS161’s black coating provide flexible aesthetic options to match a wide range of door frames and interior design schemes. Their compact, low-profile form factor makes them suitable for mounting on interior or exterior doors without obstructing movement or sightlines. Point-able coverage allows installers to focus sensing precisely where it's needed—minimizing false alarms and ensuring reliable detection across varied door configurations and installation heights.
• Audible door monitor with built-in sounder — The built-in sounder offers immediate audible feedback during exit attempts and security events, enhancing user awareness and safety. Sound levels can be adjusted to accommodate different environments, from quiet office spaces to bustling lobbies, ensuring clear notification without contributing to noise pollution. The audible alert complements visual indicators and integrates with alarm or access control systems for comprehensive situational awareness.
• Robust reliability for high-traffic environments — Bosch designs these sensors to withstand demanding conditions typical of office buildings, hospitals, schools, and commercial spaces. With sturdy enclosures and proven sensing technology, the DS160/DS161 maintain stable performance across shifts and seasons, delivering dependable operation even in environments with electrical noise or frequent door usage. The timers and monitoring features work in the background to support consistent security outcomes while reducing the need for frequent maintenance interventions.
• Seamless integration and flexible installation — The DS160/DS161 are built to integrate smoothly with Bosch access control ecosystems and other security management systems. They support flexible mounting options on frames or heads and are compatible with a variety of door types, including swinging doors and doors with electric strikes. Easy wiring, configuration, and commissioning help installers deliver reliable REX functionality with minimal downtime, enabling rapid deployment in new projects or retrofit scenarios.

How to Install Bosch Request-to-Exit Sensor, Sounder

Installing the DS160/DS161 involves planning sensor placement, mounting hardware, wiring to the door release and access control system, and configuring timing and monitoring settings. Follow these general steps to achieve a reliable REX solution while maintaining safety and uptime:

• Plan placement to ensure accurate sensing and reliable audible notification. Position the detector at an appropriate height and proximity to the door release mechanism to capture exit events consistently without unnecessary false activations.
• Mount the DS160/DS161 using the supplied hardware on the door frame or adjacent mounting surface. Confirm that the chosen location does not obstruct door operation or signage, and that the sensor is protected from potential physical damage.
• Wire the sensor to the power supply and to the door release channel in your access control panel or security system, following the manufacturer’s wiring diagrams and local electrical codes. Ensure correct polarity and proper shield termination as applicable to your installation environment.
• Configure the timer settings to control how long the door remains released after an exit request. Adjust the duration based on door type, strike strength, and expected traffic flow to balance security with ease of egress.
• Enable the door monitor function to track door status (open/closed) and set alert thresholds. Test the system by simulating exit events, validating that the sounder and door release respond as intended, and that monitoring notifications are properly routed to security personnel or management software.
• Validate integration with your access control system and other security components. Confirm that event logs reflect REX activations and that alarm or notification paths function correctly. Schedule routine inspections and testing to maintain reliability over time.

Frequently asked questions
