with air filter
In areas with interference to the environment such as, e.g. dust, an air filter
is to be used to protect the smoke detection system.
The standard air filter used is the type LF-AD-x, consisting of a plastic hous-
ing with two pipe connections, used. The air filter is automatically monitored
for dirt (blockage) by the TITANUS

air flow monitoring ar-
rangement. If the air filters are dirty, then the filter inserts must be changed
by opening the filter housing.
In extremely dusty areas (e.g. recycling plants) in which the use of an LF-AD
is not sufficient, a special filter must be used. The special filter safely holds
back the dust particles in a heavily polluted atmosphere using the filter me-
dium. The filter is guaranteed to have an even quality of dust collection right
through to the end of its useful life. Two types of special filter are available
(type SF-400 and type SF-650), the SF-650 having a longer useful life be-
cause of its larger surface area.
