OSID – Principle of Operation
Strictly confidential
Emitter
Obstruction
Dust
SmokeImager
UV beam
IR beam
An active emitter with wide beam LEDs transmit 2 different wavelengths, IR and UV, to the Imager
Intelligent software locates the specific pixels on the multi pixel CMOS imager illuminated by the uniquely coded emitter
Relative strengths of the 2 wavelength signals are compared to detect smoke and discriminate against nuisance alarm particulates
Only imager software tracks building movement without any need for controlled motor drives

UV-IR Signals
Smart algorithms Water droplets, dust, steam do affect the IR
and UV in a same way – no alarm
Genuine smoke affects IR and UV differently - alarm

Resistance to reflections
Strictly confidential
Each emitter is uniquely coded During the commissioning search, if
two or more apparently identically coded and timed signals are found, the weaker ones are rejected as false reflections

Installation & commissioning
Simple installation using a mounting bracket Easy alignment with unique Laser Tool
– Require only rough alignment due to the wide angle of view of the imager(s)
– Up to 70% time saving compared to traditional beams
Beam length up to 492 ft– Outperforming traditional beams with 50%

OSID – Powerful Financial Benefits
Low implementation costs because of simple and fast installation and alignment Only the imager unit is wired Power supplied from panel Fast and simple coarse manual alignment
Cost-effective detection for challenging buildings Provides 50% better coverage than spot and
beam detectors Spatial 3-dimensional emitters enables wide
coverage Extra layers of detection provide improved
detection time
Lower maintenance cost for larger areas Test filter at the imager or emitter No intervention costs for misalignment
