Use designated battery only.
Battery life may vary depending on usage and
installation environment.
The magnetism or magnetic field which this
sensor emits will give some influence to the
devices nearby.
Check the situation prior to operation.
* Possible cause of false alarm. Do not install the
sensor nearby the followings.
Halogen lamp
Electric dischaging lamp such as mercury lamp
Electric sterilizer lamp
Spark from welding
Electric spark (Caused by motor, pantograph)
Sunlight
Lightning discharge
High voltage electric field
All objects which emit ultraviolet rays
Although this unit is for indoor use, when it is installed in semi-outdoor, the location must be under eaves without
sunshine and rain.
Also it is recommended to set Detection timer longer than 3 sec. and Sensitivity "L".
This sensor is designed to detect ultraviolet rays in flames, and to output a warning message.
This unit is neither fire detector nor heat detector nor smoke detector. TAKEX is not responsible for damage, injury
or losses by fire, accident, calamity, Acts of God (Including inductive surge by lightning), abuse, misuse, abnormal
usage, faulty installation or improper maintenance.
This unit detects ultraviolet rays from a flame.
At the same time it detects ultraviolet rays from
other objects.
This unit does not detect the objects which are
burning without flame.
Detection area spreads out in
front of the sensor at approx.
120° conically.
The size of the detection area is in proportion to
the size of the flame and detection time.
Confirm the detection area using a lighter prior
to actual operation.
Use the optional BCW-401 universal bracket if
area adjustment is required.
When the patient who carries isotope treatment
comes near to detection area, Flame sensor may
issue an alarm, in this case set detection
sensitivity as "L".
When the performance of the installed sensor is
unstable and the cause cannot be specified, select
Sensitivity "L" and detection time one step longer
than current setting.
When the sensor window is soiled by dust, oil,
cigarette smoke, clean with soft cloth moistened
with alcohol.
* Followings are not detected by flame sensor
Flames through glass or transparent resin
Lit portion of cigarette
Burning charcoal or briquet
Electric stove
Smouldering object
(
Prior to the actual operation, adjust the detection
area carefully and test the performance.
Ultraviolet rays are sometimes reflected by walls
or floors which causes unexpected detection
resulting in a false alarm.
