NOTIFIER OSI-R-SS Conventional Single Ended Reflective Imaging Beam Smoke

Detector

General

The OSI-R-SS is a reflector-type linear optical beam smoke detector that is uniquely suited for protecting large open areas with high ceilings, where spot-type smoke detectors are difficult to install and maintain. Ideal applications are warehouses, atriums, aircraft hangers, sporting arenas and concert halls. The beam operates primarily on the principle of light obscuration using infrared.

FAST AND EASY ALIGNMENT

Aligning the imager to the reflector is extremely intuitive, fast, and accurate. Both the infrared transmitter and the CMOS imager are contained in a movable “eyeball” – an adjustable lens assembly that can move +/- 20° in the vertical direction and 50° in the horizontal direction. Four LED directional arrows indicate the direction to move the lens, guiding the user to find the imager’s perfect alignment with the reflector. Once the optimum alignment is found, indicated by all green arrows, the lens is locked with a slide lever. A paintable cover is then placed over the front to secure the lever in locked position.

RESISTANT TO BUILDING MOVEMENT

The infrared transmitter and receiver imager generates a beam of light towards a high-efficiency reflector. The reflector returns the beam to the receiver where the received signal is analyzed. The change in the strength of the received signal when smoke enters the area between the unit and the reflector is used to determine the alarm condition. The receiver imager has a wide 12° field of view that automatically tracks the reflector in case of building movement or support structure movement. This allows the OSI-R-SS to be highly resistant to movement, eliminating the number one cause of false alarms and/or faults with traditional beam detectors.

RESISTANT TO SUNLIGHT

Optical filtering, high-speed image acquisition and intelligent software algorithms provide the OSI-R-SS system with higher levels of stability and greater resistance to high level lighting variability. This provides better resistance to sunlight in its field of view, helping to prevent false alarms when saturated by sunlight, reflected sunlight or any other very bright light sources.

RESISTANT TO FOREIGN OBJECT INTRUSION

Advanced smoke imaging techniques allow the detector to avoid false alarms from partial and sudden blockage from foreign object intrusion.

TIME-SAVING AUTOMATIC SENSITIVITY SETTING

Unique in the market, the sensitivity of the detector is selected and set automatically at the optimum sensitivity based on the size of the reflector measured in the field of view. The single-ended beam smoke detector is easy to install and adjust. Only the head unit needs to be wired, and the “eyeball” can be aimed without adjusting the detector mounting.

DRIFT COMPENSATION

The detector incorporates automatic drift compensation, whereby the detector will adjust its detection thresholds in line with any long-term signal reduction of the beam caused by dust or other contamination of the optical surfaces.

EQUIPPED WITH BUILT-IN IMAGER HEATER

The imager ships standard with an internal heating option to prevent condensation on the optical surface. (External power supply required.)
