UBS1RF Optical Smoke Alarm
OverView
This optical smoke alarm is a re
detection and alarm device which gives
o an audible and visual warning when
it detects the presence of smoke within
a specially designed detection
chamber. Optical smoke sensors
are less prone to false alarms than
ionisation sensors which have
previously been more commonplace,
whilst also being slightly more sensitive
to slower, smouldering res typically seen
around electrical equipment and the fabrics
used for furniture. They are ideal for living rooms,
bedrooms, hallways and near kitchens (but not in kitchens).
During standby, the LED will ash every 50 seconds to indicate normal operation.
When in alarm mode the LED ashes approximately once per second and the
alarm enters into one of the alarm patterns described in the Alarm Signals section.
