Retro-Fit Sensors

  • Installs on existing HID fixtures rated 175-400 watts
  • Turns any HID fixture into a dimming fixture
  • All-in-one construction: PIR sensor, switching relay and dimming capacitor in the same UL-approved enclosure
  • Self-adjusting universal multi-volt design: 120-480VAC
  • User-adjustable 1-15 minute activity timer
  • Guaranteed start-on-high feature assures rated lamp life
  • Interchangeable Fresnel lenses matched to the application
  • Available with optical fiber ports for zone control
  • Intended for off-fixture mounting via STOW cord

Bi-level dimming can be added to HID fixtures that are already installed—even fixtures not equipped with bi-level ballasts! Viewpoint offers retrofit motion sensors for 175-400 watt HID fixtures regardless of line voltage or manufacturer. Our retrofit sensors don’t require swapping out capacitors in the ballast to achieve bi-level control.

Built-in Dimming Capacitor
Viewpoint’s HID retrofit sensor contains its own built-in dimming capacitor that works in conjunction with the capacitor supplied originally with your fixture. Our internal capacitor is tailored to your fixture’s specifications and reduces lamp wattage by 50% when aisles are unoccupied.

Easy Two-Wire Installation
Viewpoint’s retrofit sensors are two-wire devices that connect in series with the fixture’s existing capacitor. The line voltage of the fixture doesn’t matter because the sensor derives its operating power from the secondary side of the ballast.

All-in-One Construction
HID retrofit motion sensors feature a unitized injection-molded enclosure housing the PIR sensing element, power supply, dimming relay and oil-filled capacitor. Unlike Viewpoint’s PIP-200 series HID sensors that work in conjunction with dual dimming capacitors inside the fixture, the HID retrofit sensor is too bulky to hang from the reflector.

Typical installations for the retrofit sensor suspend it from ceiling supporting steel using a Viewpoint-supplied bracket. The motion sensor is equipped with STOW cord sufficient to allow remote mounting up to four feet away from the fixture.

Guaranteed Lamp Start-On-High
Viewpoint’s microprocessor-based architecture fosters full rated HID lamp life by assuring that the lamp always starts on high, even after AC power bumps or loss of fiber optic signals.

Available in Fiber Optic Switch Pack Format
Viewpoint offers a PSP-900 series HID retrofit switch pack that has no motion sensing capability. The switch pack gets its commands from nearby motion sensors, wall switches, or photocells using plastic optical fiber. Retrofit switch packs are cheaper than full-featured motion sensors and do not require downward pointing.

An important plus of retrofit switch packs is that they can be mounted to the HID ballast housing without causing excessive fixture tilting.
