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 the direct connection to the Excel system, the SHC protection device module must be used.

Commissioning of the system is performed using an alignment kit that includes a handheld interrogator, telescope, carry case and test filters. Other accessories include a deluge shield/sunshade, gassing cell, and handheld interrogator protection device.

A calibration has to be ordered with every Searchline Excel.
