2104N1010 Honeywell Excel cross-duct gas detection system, short range (0.5 to 2.5m), 4 to 20mA (source) and Modbus outputs, UL, fully wired with flexible conduit, electro polished 316SS.

P/N: 2104N1010

Excel cross-duct gas detection system, short range (0.5 to 2.5m), 4 to 20mA (source) and Modbus outputs, UL, fully wired with flexible conduit, electro polished 316SS. Includes detection block, single tile heated reflector panel and 316SS mounting plate. Methane calibration only. Note Duct Mounting Kit [2440K0004] must be ordered separately.

The Honeywell Excel Cross Duct is a Hazardous Area certified infrared open path gas
detector, for use in HVAC intakes and exhausts. The handheld interrogator has been certified for use in hazardous environments and is a tool for commissioning and maintenance. For direct connection to the Excel system, the SHC protection device module must be used.

Alarm levels should be set no lower than 20%LEL for the short range unit and 10% for the long range unit. The installation must be made where it is protected from dirt and condensation. Regular routine maintenance should include cleaning the reflector tiles, re-zeroing and functional test using the test filters.

There are 2 types: Short Range for ducts 0.5m – 2.5m width (ATEX and UL) and Long Range
for ducts 2.5m – 5.0m width (ATEX ONLY). Hazardous area approvals include European (ATEX) and North American (UL). Receiver output is 3 wire 4-20mA selectable sink or
source.

Standard calibration is Methane (gas mixtures where Methane is the main
constituent (>70%) and the balance is other hydrocarbons).
