distance & positioning guidelines
these guidelines are given as a guide only and it is important
that you refer to your appropriate governing standards at all
times.

what distance?
The standard fire beam will be suitable for distances of over 5m to 40m to the
reflector.If you require 40m to 80m you will need to use the mid range reflector
extension kit. For ranges of 80m t0 100m you will require the long range reflector kit.
5-40 metres the standard firebeam The standard firebeam comes boxed with the head unit, low
level controller, one reflector, 3mm allen key, test filter and quick start installation guide
this should be used for distances over 5m and up to 40 meters
40 - 80 metres = the standard firebeam + mid range 40 to 80m kit
for distances 0f 40 metres to 80 meters you will need to use the standard firebeam and a mid range extension kit (the mid range kit comes with a back-
ing plate and 3 extra reflectors, you will need to add the reflector from the standard kit to the mid range kit with the screws provided)

80 - 100 metres
80 - 100 metres = the standard firebeam + long range 80 to 100m kit
for distances 0f 80 metres to 100 metres you will need to use the standard firebeam and a long range extension kit (the long range kit comes with a
backing plate and 8 extra reflectors, you will need to add the reflector from the standard kit to the long range kit with the screws provided)
add the reflector from the standard firebeam to the
long range kit with the screws provided
what position?
A roof is considered flat unless the height of the apex is greater then 0.6m. If the roof
is flat thefirebeam system can be placed anywhere under the roof between 0.3m and
0.6m below the roof, up to a maximum height of 40m from the floor.Thefirebeam has a
detection area of 7.5m ether side of the beam.
If the roof is considered to have an apex, place thefirebeam system 0.3m to 0.6m down from
the top of the apex, up to a maximum height of 40m from the floor. The maximum protected
area either side of the beam can be extended by 1% for every degree of roof pitch, see the
example below
Always mount thefirebeam system on a solid construction that is unlikely to flex
Mount over 2.7m from floor level to avoid to people walking through the beam, and
consideration should also be given to the possibility of obstruction by fork lift trucks
and the like.
Avoid pointing the head into direct sunlight.

step three. commissioning
to commission the fire beam you must follow the simple procedure below
1. do NOT put up the reflector or COVER it if in place already!
2. power up the unit - you will see
then the screen will default to
3. access the menu system by pressing enter
4. scroll through the menus until you get to commissioning
5. enter commissioning and enter pre-alignment
(pre alignment is probably the most important part of commissioning)
6. you will see this screen

P=pre-alignment

Y(vertical)

7. signal power starts at 10% and the receiver sensitivity starts at
5% and automatically increases until a received signal from the
blank wall without the reflector of between 5 and 7% is
achieved, it will then stop
if you are covering a distance of over 50 meters you should be
achieving signal power of over 60%, if you are receiving less it’s
possible that you are picking up a reflection from something
other than the target blank wall. By moving the beam
(looking at the wall) left (x-) right (x+) up (y+) and down
(y-) you can move the beam away any obstacles to
achieve higher signal power
8. Once you are happy with the power readings press enter
and confirm by pressing the right key. The manual alignment
menu will appear press enter to enter.
you will now seen this screen

9. NOW place or uncover the reflector on the blank
wall directly opposite the beam head with a clear path though
obstructions such as girders etc.
It is important that there is a clear line of vision between the reflector and any
obstruction -the beam head must see at least 200mm of clear wall around the reflec-
tor to enable successful auto alignment.
Once the reflector is in place the AQ value should jump up
meaning that the head is now seeing the
reflector.
If you have received a AQ reading of over 40% go to Auto
Alignment point 10.
you need a reading of at least 40% to proceed to Auto align-
ment. If you do not receive an AQ signal of 40% it means the
beam head is not seeing the reflector. You will need to move
the beam head until you receive an AQ reading of above 40%
ideally over 100%
If you are presented with the screen below (AQ-air quality could be any number up to 40%)
Now look at the position of the reflector in relation to the beam head. You will need to
angle the beam toward the reflector by moving the head about its X or Y axis
using the internal motors
In the example on the next page you will notice that the reflector is below the line of
fire of the beam. So in this case you would need to lower the angle of the beam (-Y)
until you receive a AQ (Air Quality) reading above 40% sensitivity. (40 steps of the motor =
1degree of movement)
The minimum response you need to see is 40%
(below this figure the beam will not self align in the
next procedure) the higher the number the better - this
can be over 100%

40 steps = 1 degree of movement
Adjustments can now be made to the Xand Yaxis by using the
left(x-), right(x+), up(y+), down(y-) keys. Looking at the reflector
this will move the beam across the reflector like so
(40 steps = 1degree) (you can hold the key down for faster increments)
in the example above moving the yaxis down(y-) results in a greater
% air quality
Wait for x / y values to finish moving to asses your AQ result
beam head reflector
Press enter to exit manual mode and enter Auto Alignment
Try and achieve as good a result as possible - it must be over
40% or auto align will abort. (the better the result the shorter the
auto align time will be - a result over 100 is good!)
10. Having received a AQ reading of over 40% in manual mode
press enter to exit manual and enter again to enter
auto alignment
press enter and the beam head will automatically align on the reflector
9

Note: if you break the beam whilst it’s auto aligning it
will automatically abort, reset by pressing the left back
button and pressing enter to re-start auto alignment
the alignment could take up to 30 minutes or more
depending on how much aligning is required. Once com-
plete you will see a Align Complete notification, simply
press the left back button to exit and your firebeam is now
ready and commissioned
you will now see this screen. Air Quality may fluctuate
slightly around a couple of %.above and below 100
first you will see the signal power readings and receiver
sensitivity drop if the received signal reading is over 100%.
once at 100% or if the reading is under 100% thefirebeam
will automatically move its X and Y axis until it is positioned
on the reflector. (This operation could take 30 minutes or
more)
step four. testing
to test that the firebeam is aligned correctly you will need to carry out two tests.
Your firebeam has now been commissioned and tested.
1. a filter test for ‘Fire’
place the filter provided over the eyes of the firebeam.
having done this (after 10 seconds) the red fire LED will flash on
both the head and on the controller and the word FIRE will
replace NORMAL on the low level
controller display
2. a reflector test, to check that the beam is reflected
back from the reflector
cover the reflector completely within one second. If the beam is
correctly targeted on the reflector a fault condition will occur (after
10 seconds). A amber LED will flash on both the head and on the
controller, the word FAULT will appear
in the display
