Det-Tronics X3301A4N11W2 (part number 028104-035) is an X3301 multispectrum infrared (IR) flame detector for fires from light to heavy hydrocarbon fuels. Its automatic Optical Integrity (oi) feature performs a calibrated performance test once per minute to verify complete detector operation, so testing with an external test lamp is not approved or required.
In the X3301 model matrix, this version is aluminum with four 3/4 in. NPT ports and relay outputs, carries FM/CSA/QPS/ATEX/IECEx approvals, and has a Division/Zone Ex d classification. The detector is suitable for indoor and outdoor use, and a Q9033 mounting arm is required for installation.
