The SK-Ion has responsive, yet
high operational stability for an
extremely wide range of uses. The
SK-Ion can be used in areas where
early warning of trouble from superheated
or flaming combustibles is
The SK-Ion detector incorporates a
single source dual chamber
designed to respond quickly in to a
broad range of fires.
The SK-Ion ionization smoke
detector has two chambers: a
sampling chamber, and a reference
chamber. Smoke or invisible
combustion gases can freely
penetrate the sampling chamber,
but the reference chamber is
virtually closed to prevent easy
entry. With both chambers ionized
by a single radioactive source, a
very small current flows.
Presence of visible smoke or
invisible gases greatly influences
the current flow in the sampling
chamber, changing the voltage
ratio between the two chambers.
This difference is amplified inside
the detector. After reaching the
critical level, the detector triggers
The SK-Ion includes two LEDs on
each sensor which light to provide
a local, visible sensor indication.
The status LED lights continuously
during an alarm.
