Burberry’s flagship store at 121 Regent Street in London, opened in 2012

44,000 square-foot space is divided into rooms themed as Bespoke, Acoustic & Experiences

Housed in a Grade II listed building, originally created in 1820, the store was renovated by

British craftsmen, from stonemasons to cabinet-makers, highlighting the building's old features

Las ventajas con respecto a los detectores de haz de luz

tradicionales obedece a cuatro mejoras de diseño:

Emisión de Frecuencia Dual IR y UV

Imagen Digital vs. photodiodos

Innovador Método de Alineamiento

Algoritmos inteligentes

Por qué es mejor la Tecnología Dual IR y UV?

Units mounted opposite one another

Optically aligned for maximum received signal

(manually or with software controlled motor-

drives)

Single IR frequency

Use IR led to transmit and photo diode to receive

Infra-red light beam dims with smoke or partial

blockage

If received signal falls below a threshold for a

delay period then a fire alarm is signaled

Nuisance blockages are recognized when the

signal falls suddenly (e.g. 90% within 5 seconds)

Smoke Imager

UV beam

IR beam

Active emitter LEDs transmit wide beam IR

and UV to the Imager

─ IR and UV have differing wavelengths

─ Respond differently to smoke

Relative strengths of the UV & IR are

compared

─ Detect smoke

─ Discriminate against particulates that cause

nuisance alarms on traditional beams

Software locates illuminated pixels on the

CMOS imager

─ Each emitter is uniquely coded

Imager software tracks building movement

─ No controlled motor drives

Respect the scale and

OSID Opción de colocar Multi-Emitters

Multiples coberturas

Imagers can be configured with various

lenses, 10°, 45° and 90° field of view

Multiple Emitters with wide beam LEDs are

placed on the opposing wall and aligned

Up to 7 emitters may be used at the same

time with a 45° and 90° imager. The

10° FOV imager caters for 1 emitter

Emitters can be positioned on multiple

planes

Emitters flash in pseudo-random sequence

to avoid timing collisions

Emitters communicate to the imager by

data encoded on the LED pulses to report

status, including battery condition long

before replacement is needed

Beneficios Notables

Inicializacion Terminada

• The image will now show the location of

the various emitters with a green icon

and a number

• Numbering of the emitters is from left to

right from the position of the imager

• If any faults now occur, the Emitter

icon(s) will be yellow. Type of fault will

show top right of screen and next to the

Emitter # n location

• For demo purposes, a fault can be

forced by blocking the beam

•For a new image click ‘Acquire’ button,

the image does not refresh automatically

• Now you are OK to demo

Imager alignment could have been better!

Prueba de Humo

Alarma de Humo

A Filter is included in the demo kit

3rd party filters might alarm – but

don’t bank on it

The filter will highlight the alarm

mechanism

I.e., the larger the difference

between IR and UV the faster the

alarm will be accepted and detected

There is always more UV than IR

signal

UV detects smaller particles than IR

The detector will remain in alarm for

a short while after the alarm is gone

(hysteresis)

Obstrucción de Objetos

IR and UV are both fully

obscured. IR signal ‘hidden’

behind UV. UV or IR is selectable

Fault signal but no alarm

Obscuration needs to last, around

9 sec for 3+ emitters and around

30 sec for a single emitter, to

have a fault signal

When obscuration is removed

signal will drop back to normal

Movimientos de la Estructura

Make sure the Large Particle Alarm

(Dust rejection) Dip sw. 7 is set to

“on”

Insert the laser screwdriver in any

emitter as if you were aligning it.

With the laser turned on, rotate the

emitter +/- 1° out of its normal

alignment in one direction

Wait 30s and give it another 1°and so on until about 5 °

You will see a ‘step function’ as in

this graph

Stop at 5 °. Point made!

Luz Reflejada

Use torch lamp, camera flash,

laser screw driver, laser

pointer,…

Shine into the imager from a

distance

You should register no change

and no faults

You can bring the light source

close(r) to the imager provided

you do not ‘blind’ the imager.

Watch the graphs

With the light source on you can

demo an alarm with the filter

Partículas de Polvo

Blow/spray talcum powder in the

beam path – but test first

You will need ‘a lot’ to get to some

reasonable peak

There will be no alarm

Invite customer to have a go – fun

but messy !

Insectos (Arañas, Telarañas)

Los Beams normales se ponen

muy fácilmente en alarma con

insectos como arañas ya que este

patrón es muy similar a la alarma

del IR que utilizan.

Make (or tame!) a spider

Bits of string work well

Wave it around in front of the Imager

lens

You will get ‘spikes’

Alarm should not occur.

Vapor de Agua

Spray fine water droplets in front

of the imager in the beam path

It is not a problem if some of the

droplets hit the imager (see

picture)

The result is similar to dust – no

alarm

BUT – keep an eye on the UV &

IR trend

Estratificación

STRATIFICATION

The effect which occurs when smoke,

which is hotter than the surrounding air,

rises until equal to the temperature of the

surrounding air, causing the smoke to stop

rising.

This typically happens in atria covered

with windows where the air is heated by

the sun

Adding extra emitters at lower level will

result in a faster detection of smoke

Estratificación – Malla de Detección

Detection grid

Using 2 sets of OSID create a grid that

allows for early and cost-effective detection

at all levels of the atrium, at ground level as

well as at the top level.

The grid uses OSID’s horizontal and vertical

spatial performance to crate a full coverage

with minimum wiring costs

Difficult & Time Consuming to Align & Install

─ Use of ball and socket housing and unique laser alignment tool reduce time of install up to

70%

Large particle obscuration rejection

─ Use of UV & IR in specific wavelengths assist in evaluating whether obscuration is caused

by small particles in the physical size resembling smoke or from larger particle (i.e. dust,

steam, insects, fork-lift, ladders, etc.)

Tolerance to building shift and vibration

─ The multiple pixels of a CMOS imaging chip as opposed to a photodiode along with the

uniquely coded light beam from an emitter provides the ability to track the position and

tolerate movement

Foreign light intrusion

─ The Imager is fitted with a dyed glass filter, designed to be almost opaque except to all but

two wavelengths of interest
