Suspension mounting
Suspending the Smoke Screen is achieved using a ‘Suspension Kit’ comprising a length of unistrut, two sections
of threaded bar and fixings.
Suspension Kit Contents
(all M8)
Unistrut 1 x 1 metre
Threaded bar 2 x 1 metre
Fixings:
1 x ceiling hole surround
2 x drop-in anchors
6 x full nuts
4 x 25mm washers
2 x 38mm washers
2 x channel nuts
Prepare the Smoke Screen by fitting the angle
brackets. Fix the required length of M8 threaded
bar to the bracket using 4 x nuts and 4 x 25mm
washers.
Fix the unistrut into place. There are a range of
fixings to accommodate concrete ceiling,
girders etc.; if in doubt contact the fixing
supplier. Attach the threaded bar to the unistrut
using the channel nuts, 38mm washers and M8
nuts. Once this is done the Smoke Screen can
be lifted into position and the set screws
tightened as above.
Any fine adjustments can be made at this stage
as the nuts and the threaded bar will take the
weight of the Smoke Screen.
The final assembly, viewed ‘through the ceiling’
is in the photo. Any hole made in the ceiling
below can be made good with a cosmetic hole
surround.
2.5 NOZZLE CHANGING
To change the nozzle, first remove the front cover then remove and replace the nozzle using a 10mm ring
spanner, sealing it with PTFE tape and ensuring that an angled nozzle is seated in the correct orientation. The
Smoke Screen is delivered with a single-hole straight nozzle plus an extra 1-hole 30 deg angle down nozzle. The
following are also available – 2-hole horizontal, 3-hole horizontal, 1-hole 30° angle down and 2-hole 30° angle
down.
Be aware of high voltage in the block
area. The electrical supply should be
switched off before working in the
heater block compartment.
This operation is usually carried out
during installation. If the Smoke Screen
has been in service the nozzles will be
extremely hot and will cause injury if
touched. Therefore, the Smoke Screen
should be switched off and time should
be allowed for the nozzles to cool.
