Honeywell FS-OSI-RI Intelligent imaging beam smoke detector including reflector, UL listed

NOTIFIER’s FS-OSI-RI(A) intelligent addressable reflector-type linear

optical beam smoke detector 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. The FS-OSI-RI(A) detector is a combined

transmitter/receiver. It is compatible with AFP-3030,

N16 series, NFS-320, NFS2-640, NFS2-3030, and NFW-50X,

NFW-100X fire alarm control panels in FlashScan® or CLIP mode.

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

FS-OSI-RI(A) 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 FS-OSI-RI(A) 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.
