Technical data
This depends on the model of detector head fi tted to the duct
smoke detector. Please refer to the product guide for the individual
head for full details.
The relay is specifi ed as 1A at 30V DC, resistive load.
Troubleshooting
Before investigating individual units for faults, it is important to check
the system wiring is fault free. Earth faults on data loops may cause
communication errors.

General
Duct smoke detectors provide early detection of smoke in the
air moving through heating and ventilation (HVAC)ducts in
commercial and industrial premises. Their purpose is to prevent the
recirculation of smoke from an area on fi re to areas unaffected by
the fi re.
A duct smoke detector comprises a plastic housing with two
air tubes (inlet and exhaust) and a mounting base for either a
conventional or an analogue addressable point smoke detector.
Duct detector part no 53546-021 has a mounting base for Series
65 detectors, part no 53546-023 has a mounting base for Orbis
detectors and part no 53546-022 has a mounting base for XP95 or
Discovery detectors. Part nos 53546-021 and 53546-023 are fi tted
with volt-free relay contacts that may be used as required.
Both ionisation and optical detectors may be used in the duct
detectors. See overleaf for a list of suitable detectors
Caution: duct smoke detectors are for indoor use only and are
not designed to offer early warning of fi re or to be used as a
replacement for a standard fi re detection system.
When using the S65 or Orbis duct detector on a conventional panel,
it is recommended that only one unit be connected per zone.
Note: when installing duct detectors observe local codes of
installation such as BS5839-1 or NFPA 90A
Principles of operation
The duct smoke detector is fi tted to the side, the top or the bottom
of the ventilation duct and has two tubes which extend into the air
duct through holes in the duct wall. The perforated inlet tube which
spans the duct is placed in the airfl ow upstream of the exhaust
tube which causes a pressure differential in the duct detector. Air
is sucked up the inlet, across the detector and exhausted back
into the air duct. The duct detector may be used in air speeds of
between 0.5 and 20m/s.
Sampling tubes
The duct smoke detector is designed to operate in ducts with a
width of between 300mm and 3 metres. An inlet tube of 360mm,
suitable for duct widths up to 560mm, is supplied as standard. This
tube needs to be attached only to the duct detector housing.
Longer inlet tubes for wider ducts may be ordered separately:
300—750mm
750—1500mm
1500—3000mm
Tubes in duct widths above 560mm should be long enough
to reach from one side of the duct to the other and it may be
necessary to use a tube that is too long and cut it to slightly more
than the duct width. If the tube is longer than 90cm it needs to
be supported on both sides by a hole that should be cut in the
opposite wall of the air duct, allowing the tube to protrude slightly.
The tube must be closed with the small red bung provided. The
exhaust tube does not need to extend across the duct and is
therefore supplied at a fi xed length.
