TheHoneywell Analytics Searchline Excel Cross-Ductis a Hazardous Area certified infrared open path gas detector, for use in HVAC intakes and exhausts. 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).
The DX termination unit (UL only) provides convenient mounting and field wiring connections as well as an intrinsically safe connection socket for the Handheld Interrogator. Additionally, the DX termination unit (UL only) allows for a multi drop Modbus RS485 interface. The Handheld Interrogator is a commissioning / maintenance tool and is certified for use in hazardous areas. For direct connection to the Excel system, the SHC protection device module must be used.
It is important to ensure the suitability of an application for Excel Cross-Duct before ordering. 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.
