DETECTION AREA
1)
Detection area spreads out in
front of the sensor at approx.
120° conically.
2)
The size of the detection area
is in proportion to the size of
the ame.
The size of the detection area
increases with an increase in
ame size and duration.
When the object of detection is from a source such as a lighter,
con rm detection throughout the area.
3)
Use the optional BCW-401 universal bracket when area adjustment
is required.

2. Ignite a lighter etc. within detection area for
more than the set time.
3. After the set time, buzzer sounds intermittently
and LED ashes. (Alarm action)
4. 10sec. after the
ame goes off, the above
〔
alarm action ends.
When external output is used by wiring,
a continuous output is issued during the
above 3. and 4. alarm action.
Con rm the operation of the connected
devices.
Do not use a lighter in no fire
zone because it is dangerous.
In such case, operation test
have to be done in other place
with sensor only.
