Siting
A S-Quad device plugs into a dedicated Base that is installed in
the protected premises. The Bases should be sited in locations
as defined by the project plans and by BS5839 : Part 1 : 2002.
Do's and Don't
&
DO NOT locate smoke detectors where products of
combustion may be present such as kitchens,
garages, furnace rooms, welding shops etc.
DO NOT locate heat detectors above boilers or
heaters or where the temperature is normally very
high or liable to sudden fluctuations.
DO NOT locate smoke or heat detectors: -
• In dusty or dirty environment.
• Near heating or air-conditioning grilles.
• Outdoors in stables, sheds etc.
• In excessively damp areas.
• In dead air spaces at the junctions of
ceilings and walls.
• At ceiling locations where a ‘thermal
barrier' may exist.
DO NOT locate a CO detector: -
• In buildings where farm animals are kept.
• In excessive damp areas.
• In battery room where non sealed battery
are kept.
• In a Car park where exhaust fumes will
be present.
Follow recommendations detailed in section 22 of
BS5839 : Part 1 : 2002
Metal back box
A metal back box must be used for base or semi-flush mounting.
The earth continuity must be maintained throughout the whole
loop. The earth must be securely connected to the back box.
In - Out wiring to S-Quad bases
Programmable input/output
&The 34703 Slave Relay unit and 34703
Slave LED indicator unit are NOT supported for use
with S-Quad fire sensors. The Slave units are only
compatible with 34xxx range of fire sensors.
All S-Quad devices can be configured as either monitored input
or unmonitored output. The factory setting of the programmable
input / output is unmonitored output, to drive an external repeat
LED without a series resistor.
There is a maximum cable length limit of 15 metres from the
S-Quad base to the external I/O Unit.
The input can accept signals such as fire, non fire or fault, these
are configured during commissioning. As a fire input it is possible
to connect a conventional Manual Call Point (non UK application
only) with a series resistor of value 470 Ohms coupled with an
end-of-line 10Kohms resistor. In this case the fire input is fully
monitored for open or short circuit faults.
The input can be setup as a non-fire or fault input using a similar
arrangement with series and parallel resistors as shown. It is
possible for such an input to trigger a command that is
configured to action an output elsewhere in the system to control
plant equipment such as the ventilation system.

Tools
An extractor tool allows removal and fitting of the S-Quad device
head into the base. By fitting a screw-on adaptor, the tool can be
used to remove the sensor dust cover.
To remove the S-Quad
Fit the tool onto the S-Quad. Turn S-Quad anticlockwise until it
stops and then remove the S-Quad from the base.
To fit an S-Quad
Fit the S-Quad on to the tool. Offer S-Quad to base and rotate
clockwise until it moves upwards on to the base and rotate it
again until it clicks and goes no further, the lines on the base and
S-Quad will align.
To fit the dust cover using tool
Place the dust cover onto the tool inside the cradle. Offer the
cover to the S-Quad, locate and push to fit it onto the assembly.
Withdraw the tool when the dust cover is in place.
To remove the dust cover using tool
A dust cover remover tool must be fitted to the main tool to
extract the dust cover. Press the pad of the dust cover remover
tool onto the dust cover, this creates an air tight grip, to allow the
cover to be pulled off from the S-Quad.

S-Quad Semi-flush
fixing kit (S4-FLUSH)
An S-Quad device can be semi-flush mounted to a ceiling tile to a
depth of the approximate 20mm, which is slightly deeper than the
base assembly. To semi-flush mount a special housing must be
used, which consists of a main assembly and a trim ring.
"There is an enhanced volume output of sound
and speech from a flush mounted S-Quad.

Enclosure ABS
Colour RAL 9010
Storage Temperature -20°C to 70°C
Ambient temperature -10°C to 50°C

S-Quad
Trim ring
Cross section
of Ceiling Tile
Flush shroud
S-Quad Base
Do not over tighten the clamping
screws as this will cause the
clamps to cut into the ceiling tile.
Metal back box
Cut a 140mm
diameter hole in the
ceiling tile.
(
)
If required use a Bi-Metal Holesaw
140mm or 146mm, from
www.shop4tools.co.uk
Insert the flush shroud
assembly into the hole
in the ceiling tile.
Hold the flush shroud
to the ceiling tile and tighten
the three screws to splay the
clamps to secure the shroud to the tile.
Locate the S-Quad Base into
the flush shroud, such that the
two locating pillars on the
shroud feeds through the two
elongated holes on the Base.
Push the Base into the shroud
until the Base click locks into
the shroud.
Offer the trim ring to the shroud
and slowly rotate ring clockwise until it
clicks and goes no further. This will
lock the ring in position.
Fit the metal box onto the back
of the flush shroud using the
appropriate fixing screws to secure
the box to the flush shroud.
Offer the S-Quad to the Base
and rotate the S-Quad clockwise
until it moves upwards into Base,
and then rotate the S-Quad again
until it clicks and
g
oes no further.
Make the cable connections.
