+ 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
fire
beam 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 the
fire
beam 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 the
fire
beam 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 the
fire
beam 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.
