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".

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.
