ASSEMBLY
FD-SSA
Smoke sensor assembly is developed to detect
smoke in ventilation ducts and combines a smoke
detector and an adaptor system where both tube and
housing are specially designed for optimum airflow
through the smoke detector. Smoke sensor provides
the signal for the fire damper which is activated when
smoke is detected. Smoke sensor assembly consists
of casing (length: 415 mm), smoke sensor and
specially designed venturi pipe inside the duct.
For proper functioning of the smoke sensor (as it
is physically connected as in the render above) a
straight length of 5 times hydraulic diameter, in the
size of the connecting duct, should be in front of the
sensor. When the sensor is installed separate from
the fire damper there are two conditions to be met:
1) Length of 5 times hydraulic diameter, in the size of
the connecting duct, should be in front of the sensor.
2) Length of 3 times hydraulic diameter, in the size of
the connecting duct, should be after the sensor.
dh=(2xHxB)/(H+B)s, dh - hydraulic duct diameter.
