Det-Tronics X3301A4N11T1 (028234-001) is an X3301 multispectrum infrared flame detector in a copper-free aluminum housing with four 3/4 in. NPT conduit entries and relay outputs (fire alarm, auxiliary and fault, with RS-485 Modbus). It carries the T approval set (SIL/FM/CSA/ATEX/IECEx/ULC/VdS) and the Ex d e Division/Zone classification. The -001 suffix is the factory software configuration: medium sensitivity with non-latching relays.

Compatibility and installation notes
- A Q9033 mounting arm is required: Q9033A (aluminum detectors only) or Q9033B (aluminum and stainless steel).
- Automatic oi checks each sensor's ability to detect fire; magnetic and manual oi tests are available, so no test lamp is required.
- Aim the detector downward at least 10 to 20 degrees; 16 AWG (2.5 mm2) shielded cable is recommended.
- The 125 ft (38.1 m) methane range quoted for the X3301 applies to the very high sensitivity setting, not to this -001 configuration.
