●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.

PRODUCT CLASSIFICATION

●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.

●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.

●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.

●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.

●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.

●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.

●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.

OBJECTS TO BE DETECTED

OTHERS

(The factory setting is 6 sec.)

＊ 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.

INSTALLATION

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.

●Sparks from areas nearby where welding is being performed

may cause false detection.

●There are many ultraviolet rays in outdoors that may cause unexpected detection. In case there are objects in the area that cause

unexpected detection that cannot be avoided through adjustment, use the accessory "area masks" to cover the area.

●There are 6 horizontal masks and 4 vertical masks. These 2 types can also be used in combination.

●Affix the area mask on the edge of the detection window while holding the tab, and tear off the tab after affixing the area mask.

●After affixing the area mask, check operation of the sensor.

●Wear gloves and do not touch the detection window barehanded.

●The detection distance depends on the size and duration of the flame. Bigger flames with longer durations can be detected at longer

distances. Smaller flames with shorter durations can only be detected at shorter distances.

* [N-HEPTANE FLAME]: Flame that burns the flammable liquid "n-heptane" that is a component of gasoline.

Takenaka uses this flame as the standard flame for measurement. Flame size fluctuates, so the above

detection areas are averages.

This function is used to set the minimum period of time it takes to

generate an alarm from the time a flame is detected. An alarm is

output when a flame continues to be detected for more than the

set time. An alarm will not be issued if the flame is extinguished

before the period of time set has elapsed.

There are two steps that this function can be set according

to the size of the detected flame.

The sensitivity setting is chosen according to the size of the

target flame because there is a correlation in the size of the

flame and the detection area.

The sensor's operation may be unstable when the setting is

"H" if there is a continuously weak ultraviolet ray noise

where the sensor is installed.

Changing the setting to "L" is effective in the cancellation of

such noise.

＊When the sensor detects a weak ultraviolet ray, the warning may be delayed for longer than the time the timer is set at.

＊Intermittent ultraviolet rays that do not continue for as long as the set time will not cause the alarm to sound regardless of their

strength.

＊When it is used outside, the recommended setting for the detection timer is 6 seconds or more.

＊When the operation is unstable and the cause is uncertain when you are using the sensor, set the sensitivity to "L" and readjust

the current setting of the detection timer to one up, and then check the situation again.

* Assuming an identical flame, the detecting distance for

"L" is half of the detecting distance for "H".

DETECTION TIMER SENSITIVITY

LED

The following 4 levels are selectable:



This product outputs an alarm when it detects ultraviolet rays emitted from flames. Outdoor installation causes much more false

detection than is experienced with indoor installation, as there are many other sources of ultraviolet rays and few shielding objects.

The 8 selectable sensitivity levels composed of 2 sensitivity settings and 4 detection timer settings have been included to prevent

false detection in such uncertain conditions outdoors. Select the set up that most suits the environment and purpose.

When the sensor issues unwanted alarms, set the sensitivity to "L" and the detection timer to the time setting that is the next longest

to the present setting.

* When the switch is ON,

The LED lights every time there is a detection.
