W867A
APPLICATION
The Det-Tronics W867 Ultraviolet/Infrared (UV/IR)
Test Lamp is a portable, battery operated source of
ultraviolet and infrared radiation that can be used for
periodic inspection of UV, single frequency IR and
UV/IR flame detection systems. It produces UV and
IR radiation to verify response of the flame detection
system without the need for an open flame, and is
suitable for use in hazardous (classified) areas. (Note:
Det-Tronics Dual Frequency IR detectors require the
model W868 Dual Frequency IR Test Lamp for testing.)

WARNING
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 Battery Maintenance
section of these instructions for further information.
CAUTION
Do not remove the shock insulators from the
lens cap or battery storage compartment.
