P/N: 2104N4224

Excel cross-duct gas detection system, long range (2.5 to 5.0m), 4 to 20mA (source) and Modbus outputs, ATEX/IECEx, fully wired with flexible conduit, electro polished 316SS. Includes detection block, quad tile heated reflector panel, Ex e junction box with M20/M25 cable entries and 316SS mounting plate. Methane calibration only.

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).
