The unit is designed for ceiling and wall mounting.
Please make sure that 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.
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.
This sensor detects ultraviolet rays at a very sensitive level, so
it will possibly detect objects other than ames.
In addition, this sensor does not detect burning objects that are
not producing ames.
Keep the detection window
straight and the adjusting
part at the bottom.
Keep the sensor angle somewhere between completely horizontal and vertical when installed outdoors.
Do not pour water directly on the sensor, as it is rain proof, 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.

This sensor is designed detect ultraviolet rays contained in
ames and to output a signal. This unit is not a re-preventing
device. It will not detect smoke or heat.
TAKEX is not responsible for damage, injury or losses caused by
re, accident, calamity, natural disasters (including inductive
surge by lightning), abuse, misuse, abnormal usage, faulty installation or improper maintenance.
Ultraviolet rays are invisible. They may be emitted by
unexpected objects. Set the sensitivity to "L" and the detection
timer to the next longer time when the sensor does not operate
properly, in case of generating an alarm when there is no
ame or when none of the "possible causes of false alarm"
listed below are present, etc.
In the case of an explosion, the sensor may be damaged before
detecting ames.
Sparks from neighboring areas where welding is being
performed
may cause false detection.
If a person who is undergoing isotope therapy (radioiodine
therapy) comes near the unit, he/she may emit radiation
sufcient to trigger the sensor.
Set the sensitivity to "L" in such a case.
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.
There are many other ultraviolet rays outdoors that may cause
unexpected detection.
Therefore, it is recommended that the detection timer is set to
longer than 6 secs. when the unit is installed outdoors.
The sensitivity will decrease in case of rain or snow in the
detection area.
Do not install the unit in locations where sparks or ames 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
railways. Sparks from
pantographs may cause false
detection.
Do not install the unit near
high voltage power lines.
Sparks from pylons may
cause false detection.
