INSTRUCTIONS Ultraviolet/Infrared Test Lamp W867
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 detectionsystem 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.)
SPECIFICATIONS
ENCLOSURE— Cast aluminum. CERTIFICATION— Class I, Division 1, Groups C and D; Class II, Division 1, Groups E, F and G. FM For storage and use in dry or damp locationsonly.
APPROVED
OUTPUT— Broadband emissions in both UV and IR spectra. APPROXIMATE OPERATING RANGE— UV detector (25 cps sensitivity setting): >50 feet (15 meters). IR detector (40 cps sensitivity setting): 5 feet (1.5 meters). UV/IR detector (16 cps sensitivity setting): 5 feet (1.5 meters). DIMENSIONS— See Figure 1. WEIGHT (APPROXIMATE)— 14 pounds (6.2 kilograms).
ELECTRICAL RATINGS— BatteryCharger Input Voltage:
120 volts ac, 60 Hz 220 volts ac, 50 Hz (optional).
TEMPERATURE RANGE— Operating: +5°F to +122°F (–15°C to +50°C). Charge: +32°F to +104°F (0°C to +40°C). Storage: +5°F to +104°F (–15°C to +40°C). OPERATING TIME— Approximately 15 minutes continuous between recharges. This will vary with the ambient temperature.

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 distancebetween 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 dischargingthe 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.

SYSTEM CHECKOUT
A system checkout should be performed 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 theatmosphere, 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 andverification 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.
