Data and Installation
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
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.
CABLE GLAND
LOOP CABLE
The input can accept signals such as fire, non fire or fault, these
are configured during commissioning. As a fire input it is possible
S-QUAD BASE
to connect a conventional Manual Call Point (non UK application
2 SCREWS TO SECURE
only) with a series resistor of value 470 Ohms coupled with an
BASE TO METAL BACK BOX
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.
