Honeywell Searchline Excel Cross Duct is an Infrared Flammable Gas Detector designed primarily for HVAC Exhausts and Ducting along with Turbine Enclosures. It is calibrated for Methane detection range 0-100% LEL. Hazardous area approved. Designed to protect ventilation ducts from gas ingress.
There are two versions Short Range for ducts 0.5m – 2.5m width (ATEX and UL) and Long Range for ducts 2.5m – 5.0m width (ATEX ONLY). The transmitter and receiver are amalgamated, supplied complete with reflector. Install transceiver with reflector positioned opposite. The transceiver measures the gas by the reflected beam signal.
Fast response T90 < 1 second allows low alarm setpoints. Alarm levels should be set no lower than 20% LEL for the short-range unit and 10% for the long-range unit. Searchline Excel Cross Duct can act as one component of a more extensive Honeywell Analytics gas detection system. Combined with XNX transmitters, a complete system can have a standard interface.
Installation needs to be made in a clean area where there is no condensation. Frequent maintenance is recommended to ensure system integrity, specifically cleaning the reflector tiles, re-zeroing and functional test using the test filters. DX termination unit (UL only) allows for wiring and mounting, configuration maintenance by the Handheld Interrogator.
