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)

Dust
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

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
