Installation and Location

Install the smoke detector with the airflow direction arrow 
on its cover pointing in the direction of airflow through the 
ducting. The detector can be mounted on the side or top of 
the duct for vertical or horizontal air flow.
If the ambient temperature varies radically, for example 
outdoors or in cold attics, insulate the detector to protect it 
from the ambient air and prevent the formation of conden-
sation inside the detector housing.
To ensure satisfactory smoke detection, the smoke detector 
should be located at a distance, in the direction of airflow, 
that is equivalent to at least 3 x the hydraulic diameter of 
the duct 

upstream of the nearest source of disturbance 

in the ducting (see the examples of sources of disturbance 
below). If it is located 

downstream 

of the nearest source 

of disturbance, its distance from this source should be equi-
valent to at least 5 x the hydraulic diameter of the ducting.
