Occupancy Sensors

Product catalog summary
Overview
BRYANT® Occupancy Sensors are designed to enhance energy efficiency by automatically controlling lighting based on room occupancy. They integrate advanced technologies to reduce energy costs and support sustainable building practices.
Technologies
  • Dual Technology: Combines passive infrared (PIR) and ultrasonic (US) technologies for reliable occupancy detection, minimizing false triggers.
  • Ultrasonic (US): Detects occupancy through sound wave frequency shifts, ideal for spaces with minor motion.
  • Passive Infrared (PIR): Detects heat movement, suitable for spaces with major motion.
  • Adaptive Technology: Automatically adjusts sensitivity and timing based on environmental changes.
Energy Saving Benefits
Occupancy sensors can reduce lighting energy consumption by 13% to 90% in typical office settings. They comply with standards like ASHRAE/IESNA 90.1 and California Energy Commission Title 24, contributing to LEED® certification.
Product Features
  • Wall Switches: Available in various colors, designed for easy retrofits without a neutral wire, featuring adaptive technology.
  • Ceiling Sensors: Offer wide coverage and combine ultrasonic and PIR technologies.
  • High Bay Controls: Suitable for large spaces with high ceilings, providing extensive coverage and dual relay options.
Specifications and Wiring
Detailed specifications are provided for different sensor models, including coverage areas, voltage requirements, and installation guidelines. Sensors are available in various configurations to suit different applications and environments.
Applications
BRYANT® sensors are suitable for offices, restrooms, conference rooms, and classrooms, optimizing energy use by ensuring lighting is only active when needed.
Specifications
  • MSP1500C and MSP600C: Ceiling sensors with 360° coverage, requiring MSCU series control units.
  • MSD2000L Series: Features adjustable time delay/sensitivity and a 360° field of view.
  • MSU2000L and MSU1500L Series: Offers long-range major motion detection with high load ratings.
  • MSD1000 Series Wall Switches: Adaptive technology with digital time delay and ambient light override.
Procedures and Installation
  • All MSP ceiling sensors must be used with MSCU series control units.
  • Wall mount sensors require MSCU series control units for operation.
  • Wiring schematics are provided for single and dual circuit applications.
Norms and Certifications
  • All sensors are cULus Listed and comply with CEC Title 24 standards.
  • MSCU and MSAR units are UL Listed and cULus Certified.
Recommendations
  • Use adaptive technology sensors for "install and forget" operation.
  • Consider dual technology sensors for environments requiring both major and minor motion detection.
Accessories
  • MSCU Control Unit: Provides 24V DC power supply for sensors and includes an internal relay for lighting control.
  • MSAR Add-A-Relay: Allows control of additional circuits when occupancy is detected.
