This sensor is designed to detect ultraviolet rays contained in
flames, and to issue a signal.
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.
◎
Carefully select the installation site and set up the sensor to avoid dead spots.
◎
Do not install in the following places.
Product classification
●
When an strong impact is given to the sensor, it may cause
damage, malfunction or less performance.
Do not handle in a rough manner.
●
Intense flames such as gas explosion's may damage the
sensor, and there may be no detection.
Others
This sensor detects ultraviolet rays contained in flames.
Therefore, this sensor may detect other sources of ultraviolet rays.
This sensor does not detect burning objects which are smoldering.

●
Do not install the sensor nearby the possible cause of false
alarm. (see section 2)
●
Do not give an impact to the sensor. it may cause damage,
malfunction and less performance to the sensor.

place. it may cause malfunction.
●
Only type-AA Alkaline battery (2 pcs.) can be used.
Do not use manganese battery because of its short life.
●
When low battery alarm is initiated, exchange the battery
immediately. If not, the sensor may not work.
●
This sensor's alarm action is 10 sec. offdelay action.
By detecting a flame, the alarm will be initiated after the set
time of timer passed.
The alarm action is continued during the fire, and stopped 10
sec. later after the extinction.
