Mechanical Installation instructions
Prior to mechanical installation
This product should only be installed by competent engineers/ installers.
All risk assessments for the installation should be site specific and carried out
by a competent person prior to installation.
All packaging must be removed with extreme care and no sharp tools should
be used, the fabric is rolled around the roller assembly and will very easily be
damaged.
Check carefully the structural measurements of the opening against the
relevant drawing.
Ensure that all walls surfaces and closing surfaces are suitably fire rated, level
and true.
The opening must be capable of carrying the weight of the complete assembly
of the fire curtain, the weight is indicated on the approved working drawing.
The opening should be equal or greater than the required fire performance of
the product.
Check the kit list is complete and all components are correct.

Head Box - Drawing ID 01/02
Side Guides - Drawing ID 01/02
• The head box is manufactured from mild steel sheet, which depending on the
length may come in pre-assembled sections. Each part of the head box is
clearly marked inside. All roller support brackets and hood support brackets
must be installed in the pre-drilled locations.
• Position the back cover of the box to the structure in accordance with the
dimensions and fixing detail indicated on the approved drawing. It is important
to use the central anchor point and position each bolt to the extremity of
each slot as the product must expand either side of the anchor point in a fire
situation.
• Check the box housing is level with a spirit level or laser device, mark the fixing
holes and drill for the specified fixing type.
• Lift the box housing and fix to the structure using the fixings and fusible
washers. Carry out a final check to ensure the box housing is level. If the box
housing is not installed level this will result in the fabric travelling sideways
along the roller tube when retracting. This will result in the curtain snagging.
• When smoke seals have been supplied they must be riveted to the head box
using steel rivets into the pre-drilled holes, if the housing has been supplied in
sections. Housings supplied in one section will have the smoke seals factory
fitted.
Now position the back section of the guide to the structure with the top edge
entering into the head box housing by 40mm. Use a spirit level or laser device
and set the guides plumb to the correct dimensions indicated on the working
drawing. Mark the fixing holes at the top of the slots to allow for expansion.
Drill for the specified fixing type.
Fix to the structure using the fixings and fusible washers. If required the guide
must be suitably shimmed to ensure they remain vertical without any twisting.

Roller Assembly and Curtain - Drawing ID 03 + 04
Attaching the Bottom Bar - Drawing ID 04 + 06
• Using the correct lifting method (minimum two people) lift the curtain and roller
assembly up to the head box. Install the dummy sliding end into the end plate
cup and secure with the M8 x 40 Allen screw. Push the roller assembly as far
as possible to the non-drive end allowing the dummy end to contract as far as
possible. Now insert the motor drive end (ensure the motor cable is positioned
on top of the shaft) into the end plate cup and secure with an M8 x 40 Allen
screw.
• The box housing should now be drilled for the motor cable to pass through
a stuffing gland, ensure the motor cable cannot snag as the roller operates.
Unwind approximately 300mm of fabric from the roller.
• Now install the head box cover by steel riveting to the end plate returns and
across the front lip. Ensure the fabric remains accessible through the slot in the
head box.
• Pull the remaining fabric from the roller assembly through the gap in the head
box. Ensure the motor cable wires are not touching each other or it will not be
possible to rotate the roller mechanism without force, which in turn will damage
the motor brake assembly. The roller should rotate freely.
• Determine the curtain drop and mark both edges of the curtain at the fully closed
fire-safe position. Using a laser or chalk line, mark the curtain across the full
width from both points.
• Place the angles of the bottom bar back to back with the 40 x 40 angle on the
same side of the curtain as the roller assembly on the marked line. Ensure the
fabric is pulled tight and clamp the angles to the marked line on the fabric. Slide
the bottom bar guide retainers between the 2 angles sandwiching the fabric, the
2 m6 holes in the retainers holes will line up with the holes in the bottom bar. Pull
the fabric flush with the bottom bar and push the two piece double cap rivets (6
at each side) through the retainers and fabric. Place a hammer on one side of the
rivet and hit the other side crushing the rivets securely together.

Attaching the bottom bar cont.
• All 6 rivets must be fitted and secured to prevent the curtain pulling through the
retainers.
• Drill through the fabric with a 6.5mm drill bit (the pre drilled bottom bar holes
should align and you should only be drilling the fabric) the bottom bar has been
factory assembled and no cutting or drilling is required. If the holes do not align
then you have not arranged the angles correctly. The rail at either end when
assembled has two 6.5mm holes drilled at 50mm and 100mm from each end. the
front and rear angle joints never align and must be fully overlapped to maintain
the rails strength. insert the M6 x 16 screw into the holes with the screwhead
on the 40 x 20 angle side roller side of the bottom bar. Attach the nyloc nut on
the opposite side and tighten accordingly. Proceed all the way along the bottom
bar until the bolts have been installed. If the screws are fitted the opposite way
round the nuts will hit the headbox and prevent the bottom bar pulling tight and
closing flush with the headbox.
• Carefully trim the excess material which is below the now assembled bottom
bar with a Stanley knife or similar, take extreme care as not to slip and cut the
curtain above the bottom bar.
Nylon cover caps are provided for the nyloc nuts.
• Curtains require a minimum bottom bar weight of 10kg per motor to close under
gravity failsafe. this allows for friction against the smoke seals and the fabric
rubbing on the guide surfaces.
• For assemblies where multi rollers are used the bottom bar is one continuous rail.
The curtain fabrics are overlapped. Where the fabrics overlap it is essential that
the fabric is pulled tight prior to the angles being secured together which will
provide a good seal to the overlapping fabrics. The fabrics should overlap true
and plum.
• Wide roller assemblies will deflect due to their own weight and curtain assembly
load. This deflection may cause the bottom bar to sag when fully retracted. To
overcome this remove the bottom bar screws in the middle of the rail and pull
the fabric through to replicate the sag at the head box. Re drill the curtain fabric
and replace the fixings accordingly. Do not over exaggerate this and check when
the bottom bar is in its fire safe position it still seals along the closing surface. If
this does not rectify the issue then packers can be inserted between the roller
tube and the fabric at the points of the sag. This will increase the circumference
of the roll and give an increase in the travel distance, off cuts of the fabric
should be used for the packers. Start small and slowly increase to achieve the
required retract position and the bottom bar pulls up flush with the head box, It
is possible to use both methods.

• CPM red light on indicates there is a system malfunction on the
panel programming, wiring or PCB failure.
• Delay blue light indicates there is an active alarm signal been
received and the panel is holding the curtains for the programmed
time in the stored settings.
• A Green light Power on indicates the panel has a healthy mains
supply to the PSU.
• Amber light Low battery fault on indicates either there is a mains
failure to the panel or the batteries are below the required
voltage and will require charging, the panel constantly monitors
the battery voltage and will detect when low, once recharged the
light will go out.
If the light does not go out after 2 hours the batteries will require
replacing. If the panel has had no mains supply the batteries will
hold the curtains in the retracted position until the low voltage
close system has been triggered, the curtains will then close in a
controlled decent but will no longer retract until the mains supply
is reinstated. If the batteries have totally depleted the LCD
screen will be blank and both batteries will require replacement.
• Alarm red light on indicates there is an active signal to one of the
panel inputs, this could be the main alarm terminal or either input
1 or input 2, this will not go off until the signal has returned to
normally closed.
• Override amber light on indicates there is an active signal to
one of the panel inputs, this could be the main alarm terminal
or either input 1 or input 2 and the override button has been
pressed, once the curtain has returned to its fire safe position
the light will go out.
