The following setting is necessary for detection performance. Read carefully to make appropriate setting.
This unit detects ultraviolet rays in a flame and issues a signal.
In the semi-outdoors, there are many objects which generate ultraviolet rays and because there are no walls or windows in open
area, there is a much higher possibility for the unit to detect those objects, in comparison with indoor installations.
The detection performance should be set using the dip switches according to the circumstances of the installation site.
When the performance of the installed sensor is unstable and the cause cannot be identified, select Sensitivity "L" and detection time
one step longer than current setting.
Detection sensitivity is selectable
H or L.
* Detection distance on "L" setting is 50% shorter than that on "H" setting.
* If the operation is unstable on "H", switch to "L".
* When installed semi-outdoor, "L" setting is recommended.
An alarm output occurs when the flame
continues for set time of detection timer
or longer.
* When the ultraviolet rays of flame are weak (it is related to size of flame and distance to the sensor), Alarm initiation may be
delayed beyond the set time.
* When installed semi-outdoor, set detection timer 3 sec. or longer.
Turn power on. In case of battery operation, the
buzzer "repeated pip" sounds. In case of DC
operated, no buzzer sounds.
Ignite a lighter etc. within detection area for more
than the set time.
Warning message sounds intermittently and LED
flashes.
After turning off the lighter, check if the output
stops at the set up time. (When external output is
used by wiring, a continuous output is issued during
the above 3. and 4. alarm action. Confirm the
operation of the connected devices.)
