PRECAUTIONS

PRODUCT CLASSIFICATION
This sensor is designed to detect ultraviolet rays contained in flames and to output 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 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.
• Keep the sensor angle somewhere between completely horizontal and vertical when installed outdoors.
• Keep the detection window straight and the adjusting part at the bottom.
• Do not pour water directly on the sensor, as it is rainproof, not watertight.
• 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 it 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 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 flame 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 flames.
• 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 sufficient to trigger the sensor. Set the sensitivity to “L” in such a case.
• 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.
• Do not install the unit near railways. Sparks from pantographs may cause false detection.
• 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 factory set is 1 sec.)

• The sensitivity will decrease in case 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 AREA

Detection Area

• The upper detection area is limited to avoid sun ray influence and other unexpected detectable objects remotely located.
• The detection distance depends on the size and time of flaming. The bigger and longer continuous flame is more apt to be detected. The smaller and shorter the flame continues, the narrower the detection area gets.

[N-HEPTANE FLAME] The flame burns the flammable liquid “n-heptane” which is a component of gasoline. Takenaka uses this flame as the standard for measurement. Flame size is variable, so the above detection areas are average.

SENSITIVITY “L”: The detection area becomes approximately 50% of the above area.

Area adjustment

• The area adjustment in wide angle allows the sensor to be installed in various locations.
• Loosen the grip bolt and ball lock and refer to “3. PRECAUTIONS” when installing. Do not forget to tighten it when finished.
• Keep the detection area downwards to avoid sun ray influence and other unexpected detectable objects remotely located when installing outdoors.
  • The direction of rotation of the left and right grip bolts is the same. Please do not rotate each in the opposite direction. Please refer to the direction of rotation described on the body sticker.

AREA MASKING

• There are many ultraviolet rays outdoors that may cause unexpected detection. In case there are objects in the area that cause unexpected detection and that cannot be avoided by adjustment, use the accessory “area masks” to cover the area.
• There are 6 horizontal 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 the operation of the sensor.
• Wear gloves and do not touch the detection window barehanded.

OPERATION AND FUNCTION

Operation
The operation LED (red) will light and start output when the sensor detects flame (ultraviolet ray) for the set up time (1 sec., 6 secs., 15 secs., 30 secs.,) and moreover when the environment is darker than the [operation model set up. In case it still keeps flaming, it will continue the above operation LED (red) lighting and output. After the flame goes out, the operation LED (red) lighting and output (off delay) will stop according to the [delay time range (2 secs. ~ 10mins.).

Mode Setting
The following settings and functions are selectable for detection and output. Use the dip switch in the adjustment box and adjustment volume which is on the bottom of the sensor.

• The adjustment volume can be turned by coins. Do not turn strongly, it may cause damage.

ADJUSTMENT VOLUME

Detection Function
This product detects ultraviolet rays included in flames and outputs an alarm. Outdoor installation would cause much more false detection than indoor installation, as there are many other ultraviolet ray factors and few shielding objects. The 8 selectable sensitivity levels combined by 2 sensitivity selections and 4 detection timer selections are made to prevent false detection in such uncertain conditions outdoors. Select the setup that suits most the environment and purpose. When the sensor does not operate properly, set the sensitivity to “L” and the detection timer to the next longer time.

Detection timer
This function sets up the minimal flaming time to detect. It outputs an alarm when the flaming continues more than the set-up time. It will not output an alarm when the flame goes out before the set time.

The following 4 levels are selectable.

• The alarm may delay when the strength of ultraviolet rays is low.
• Intermittent ultraviolet ray will not be detected.
• Timer set up with 6 secs. or more is recommended for outdoor installation.

Sensitivity
This function set up the size of the flame (the strength of ultraviolet rays) to detect.

• The detection distance for “L” is half of that for “H”, when detecting the same flame.
• When there is an uncertain operation at “H”, change the sensitivity to “L”.
• For outdoor use, “L” is recommended.

Output function

Delay time (Operation time adjustment)
The output time for daytime is off delay of detection time + set time. There are the following selections.

Day light (Operation mode)
The following output will be produced only when the circumference is darker than the setting. (day/night time discernment function) Set up according to purpose.

• For subtle settings, adjust the volume when the circumference is at the requested light level.
• Even setting for nighttime mode, it may not output a signal when the circumference is bright with lighting etc. In that case, turn the volume to the right until it outputs a signal.
• The “output only night time” function is convenient to detect only at night time in the locations that have other ultraviolet ray factors at day time.
• Please set “off” in the “Alarm memory function” when setting up this function.

Flashing
The following two output types are selectable.

Flashing is useful to threaten and notice incendiarism.

Alarm Memory Function
This function enables the identification of individual sensors in multiple sensor configurations. After raising an alarm, the memory indication LED (yellow) blinks for 3 minutes and then lights for 47 minutes. When an alarm is caused again during the lighting, it will light for another 47 minutes. <re-trigger operation>

• In case of resetting this function during blinking and lighting, turn the power off and on again. (power on reset operation)

Memory auto reset

Setting	Memory LED (yellow)
ON	Blinking (3 minutes) Light on (Auto reset after 47 minutes later)
OFF	Blinking (3 minutes) Light on (Until resetting by manual)

Manual reset: Power supply off and on again or “Alarm memory function” off.

Environment monitoring function
This function monitors the strength of nuisance by ultraviolet in the installed environment to check whether there is a cause of false alarm. When the performance of this sensor becomes unstable, please use this function to check the strength of ultraviolet.

The strength is shown by operation LED (red).

1. The operation LED (red) may be “light on” 2~3 times per 1 minute in even a normal environment. In case of more frequent lighting, there may be a nuisance ultraviolet source in the site. Therefore, please set sensitivity “L” and detection timer more than “6 secs”
2. In case the operation LED (red) lights on or blinking continues more than set detection timer, Please adjust sensitivity “L” and detection timer more than above operation LED (red) duration time.
   • The environment of ultraviolet is not always equable. It may fluctuate by varied factors. When the performance of this flame sensor becomes unstable after installation, please adjust the sensitivity to downward and the detection timer to the next longer time.
   • The alarm signal outputs at setting level (sensitivity, detection timer) even environment monitoring function is “ON”.
