Why this part number
Order 02104-N-7012 when the path length, source/sink loop and approval must be locked together: Searchline Excel, open-path Tx/Rx system, Short range 5–40 m (15–130 ft), 4–20 mA source, INMETRO (SEARCHLINE EXCEL KIT SR INMETRO SOURCE). Open-path IR covers vapour clouds that point detectors miss; T90 is under 3 s with xenon-flash solar immunity. If this SKU is short, jump to 02104-N-4044 (output) or 02104-N-4014 (approval).
Spares and mates
02104-N-7012 is Searchline Excel System. The open-path system is 316SS Tx+Rx, 0–5 LEL·m. Matrix: product-9020. Do not substitute Sensepoint XCD cartridges, XNX personalities or Excel Plus/Edge.
Typical applications
02104-N-7012 is sized for offshore decks, FPSO process areas, tank-farm bunds, compressor halls and pipe racks. Keep the beam clear after alignment; dual-band filters handle fog/rain without software masking.

Installation and service
Align 02104-N-7012 with the rifle-scope kit until the Tx/Rx optical axis is locked (±0.5°). Path is Short range 5–40 m (15–130 ft); mount on a rigid structure and keep the beam clear. Power is 18–32 VDC. Land 4–20 mA on the fire-and-gas matrix; Modbus uses DVC100(m) MKII or DX100(m). Window heaters are a standard option for severe weather.
FAQ
- Is 02104-N-7012 a point IR head?
- No. 02104-N-7012 is Searchline Excel open-path IR with a separate transmitter and receiver. Point IR is Searchpoint Optima Plus.
- Can I rescale 02104-N-7012 to 0–100 %LEL?
- Open-path range is 0–5 LEL·m (alarms typically 1.0 / 3.0 LEL·m). Cross-duct is a different 0–100 %LEL SKU family.
- Can I flip source/sink in the field?
- No. This SKU is 4–20 mA source. Order 02104-N-4044 for the other loop polarity.
- Can I mix SR lamps with LR receivers?
- No. 02104-N-7012 is Short range 5–40 m (15–130 ft). Change span with 02104-N-7022; medium/long-range lamps draw more power.
- Is 02104-N-7012 Excel Plus or Edge?
- No. Plus/Edge uses SLXL- codes. This family is Searchline Excel IR (02104-N / 2104B).
