PRODUCT CLASSIFICATION
This sensor is designed to detect ultraviolet rays contained in
flames and to issue a signal. This unit is not a fire-preventing
device. It will not detect smoke or heat. TAKEX is not
responsible for damage, injury or losses caused by fire, accident,
calamity, natural disasters (including inductive surge by
lightning), abuse, misuse, abnormal usage, faulty installation or
improper maintenance.
INSTALLATION
The unit is designed for ceiling and wall mounting.
●
Please make sure the base surface is protected with
reinforcements. In case of installation on concrete or gypsum
board, please use anchors and screws suitable for the material.
Keep the sensor angle somewhere between completely
●
horizontal and completely vertical when installed outdoors.
NG
OK
Keep the detection window
●
straight and the adjusting
part at the bottom.
Do not pour water directly on the sensor. (It is rain proof, but
●
not water tight.)
Do not install the unit in locations where high amounts of
●
steam stagnate (bathrooms etc.).
Do not install the unit in areas where the temperature is under
●
-20°C (-4°F) or over +50°C (+122°F).
Do not install the unit in an environment subject to electrical
●
noise or intense vibration.
After adjusting the angle, tighten the screws and bolts to
●
prevent the unit from falling and to maintain resistance to
rain.
A high installation location is recommended to prevent
●
vandalism. (over 2.5m)
This product is for installation on walls, ceilings, and under
●
eaves. Use the optional attachment for installation at uneven
places.
OTHERS
The detection window is made of specialized glass and is
●
fragile.
Do not touch the detection window barehanded. Oil from hands
●
may cause low sensitivity. Wipe the detection window with a
soft cloth with alcohol if it is dirty. After installation, wipe
again when necessary.
OBJECTS TO BE DETECTED
This sensor detects ultraviolet rays at a very sensitive level, so
●
it will possibly detect objects other than flames. In addition,
this sensor does not detect burning objects that are not
producing flames.

Ultraviolet rays are invisible. They may be released from
●
unexpected objects. Set the sensitivity to "L" and the detection
timer to the next longer time when the sensor does not operate
properly, such as generating an alarm when there is no flame
or when none of the "possible causes of false alarm" listed
below are present.
In the case of an explosion, the sensor may be damaged before
●
detecting flames.

Sparks from areas nearby where welding is being performed

may cause false detection.

If a person who is undergoing isotope therapy (radioiodine
●
therapy) comes near the unit, they may emit radiation
sufficient to trigger the sensor. Set the sensitivity to "L" in
cases where such persons may be near the sensor.
Do not install the unit in locations where sparks or flames are
●
usually used (kitchen, incinerator, etc.).
Do not install the unit in locations subject to severe shock or
●
electric noise.
Do not install the unit in locations where a shield object (glass,
●
transparent resin, etc.) is in front of the sensor.
Do not install the unit near
●
high voltage power lines.
Sparks from pylons may
cause false detection.
NG
＊ There are many other ultraviolet rays in outdoors that may
cause unexpected detection. Therefore, it is recommended that
the detection timer be set to longer than 6 sec. when the unit is
installed outdoors.
(The factory setting is 6 sec.)
The sensitivity will decrease in cases of rain or snow in the
●
detection area.
In cases where the detection window is covered with frost, ice,
●
etc., the sensitivity will become very low and the sensor may
not detect properly.

detection.
