دستگاه تست دتکتور شعله

The Sense-WARE® T-229/4P flame detector test lamp activates UV, IR and UV/IR flame detectors which detect in the 185-235 nm UV and 4.4 μ IR frequency ranges. For UV only detectors the maximum distance is up to 8 meters (26 ft) in the continuous mode. The test range for IR and UV/IR detectors is up to 4 meters (13 ft).
Most IR Flame detectors have an extra alarm criterion; analyzing the flicker frequency of a fire. In order to simulate the flame flicker, the lamp needs to be pulse operated. For this, the test lamp T-229/4P can be put into the pulse mode by means of a selection switch on the left side of the test lamp. The lamp then emits pulsed light with a frequency of approx. 2 Hz. After the alarm delay time the IR or UV/IR flame detector will activate.
