MP/SMP Duct Probe Units
The MP/SMP Duct Probe Units are designed to
be installed in air conditioning supply and
exhaust ducts for the purpose of monitoring the
airflow for smoke and combustion products.
The MP69 and SMP69 probe units are designed
to accept and operate with the M600 and M900
series detectors. MP35 and SMP35 duct probe
units are available for use with M300 and M500
intrinsically safe series detectors and bases. For
general applications it is recommended that
photoelectric smoke detectors rather than
ionisation smoke detectors are used.
The SMP stainless steel probe unit is designed to
withstand the more demanding environments of
the offshore oil and gas industries.
The units are designed to operate in airspeeds of
1.5 to 25 metres per second. A range of sampling
tubes from 450mm to 1500mm are available.

Warning
Duct probe units sited in the common duct work
to several extract grills may fail to respond to
smoke from any one extract due to the effect of
dilution. The MP/SMP units will not respond to
airflow of less than 1.5m/sec.
Siting
Duct probe units should always be sited as near to the point of extraction from the room as possible
and in lengthy duct work runs, at intervals along the run. Probes should be mounted at the least
turbulent sections of the ducting. Avoid installation immediately behind fans, bends or work sections.
