Open-area Smoke Imaging Detection
Reliable Fire Protection for
Large Open Spaces

Open-area Smoke Imaging Detection
Dual frequency beams Digital imaging versus
photodiodes Smart algorithms

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
8
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

Strictly confidential
10° imager with emitter at 280 ft (86 m) Forced misalignment - steps of 1°/min
1° = 5 ft (1.5 m) 4° = 20 ft (6 m) 8° = 40 ft (12 m) Fault at 9° misalignment – NO alarm
Misalignment guaranteed up to 4°

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
16
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%

Beyond projected beam detection
OSID Multi-emitter Solutions

OSIDTrue Detection Innovation
Imagers can be configured with various lenses for 10°, 45° and 90° field of detection
Multiple Emitters with wide beam LEDs are placed on the opposing wall and aligned
Intelligent software locates the pixels on the multi pixel CMOS imager illuminated by each uniquely coded emitter
Up to 7 emitters may be used at the same time with a single Imager
Emitters can be positioned on multiple planes

34
Dirty Environments
Particle size discrimination - Superior rejection of dust and intruding solid objects and safely reports smoke
Challenging applications
36
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
37
OSID - Reliable, Cost-Effective Choice for Open Area Detection
Reduced susceptibility to false alarms Dust and dirt Birds and insects Foreign objects Fog and steam
Lower installation and maintenance costs Easy to align Not susceptible to building movement
Not effected by ambient lighting
