FAQ
- Will 2104N4224 detect gas by itself?
- No. 2104N4224 is a Junction Box (Long range cross duct system 2.5m to 5.0m. ATEX approved, current source with junction box and four tile heated reflector assembly. Calibration Methane only.) and needs a Searchline Excel Tx/Rx pair.
- Can I fit an Excel Plus accessory instead of 2104N4224?
- No. Alignment scopes, sunshades and glands are IR-series specific; Plus/Edge 2017B kits do not interchange.
- Can SR and LR alignment kits be mixed?
- No. Short-range and medium/long-range kits use different scopes and mounts.
- Calibrate after fitting?
- Functional gas test after system alignment. Brackets and sunshades do not need gas.
- Lead time?
- Lot-based. Do not substitute a look-alike 2104D/02104 SKU without matching the part number.
