Control your lighting costs with photocell and occupancy sensors.

Menu

Sensors are the smart solution for minimizing energy consumption and maximizing lighting system life. Utilizing state-of-the-art electronics and optics, Keystone’s photocell and occupancy sensors provide a cost-effective solution for dramatically improving the return on your investment.

Benefits of occupancy sensors

  • Enhanced controllability of lighting system
  • Extended lamp life
  • Reduced maintenance and replacement costs
  • PIR Sensors
    Keystone’s PIR sensors intelligently signal when to turn the lights on and off using passive infrared technology. Optional interchangeable fresnel lenses provide even more control of your high bay lighting systems. The 360° lens view covers a circular area underneath the high bay light fixture. The aisle-way lens view focuses the coverage on the open aisle, not where the racks are. This provides enhanced performance with less passive infrared sensors needed. Keystone also has your outdoor sensor needs covered with our wet location high bay occupancy sensor.
