SAFETY PRECAUTIONS
Exposure to ultraviolet radiation from the W867
Test Lamp can be damaging to the eyes. Do not
look directly into the window of the test lamp
when it is on.
OPERATION
To operate the W867 Test Lamp, push the “ON” button
(see Figure 2) and aim the test lamp at the detector.
The UV and IR emitting lamp inside the W867 will flash
on and off at a rate of approximately 2 times per
second. This flashing operation satisfies the “flicker”
circuit in the IR detector. Response of the detection
system will depend upon the distance between the
W867 and the detector, and upon the sensitivity
programmed into the detection system. It may be
necessary to decrease the distance between the
detector and the test lamp in order to obtain a
response.
Do not operate the test lamp longer than is necessary
to actuate the detector. Each detector can be checked
with less than 30 seconds of operating time. It is
important to avoid discharging the battery to the point
where the battery charge level Indicating LED (see
Figure 2) is on steady. Refer to the Batter y
Maintenance section of these instructions for further
information.
CAUTION
Do not remove the shock insulators from the lens
cap or battery storage compartment.
SYSTEM CHECKOUT
A system checkout should be per for med after
installation is complete. A periodic maintenance
checkout (with minimum frequency of once every six
months) should be scheduled to ensure that the system
is in proper operating condition. Depending on the
degree of hazard and the amount of contaminants in
the atmosphere, the checkout can be scheduled more
often. Note that oil films will significantly reduce the
transmission of ultraviolet radiation through the detector
windows.
For specific system checkout instructions, see the
“Checkout Procedure” section of the instruction manual
for the flame detection system being used.
The W867 Test Lamp is a safe, portable UV/IR source
for external testing and verification of the response of
Det-Tronics UV, single frequency IR, and UV/IR
detectors. It is suitable for use in hazardous
(classified) areas, but is not a substitute for an actual
open flame test.
