Orica's electronic blasting systems include its Surface Remote Blasting System and Central Blasting System for underground operations. SURBS, which allows surface mining operations to initiate electronic blasts remotely from a safe central point, works with up to 12 of Orica's i-kon System Loggers, each of which can handle 200 detonators. The system uses coded radio signals on an assigned frequency with two-way communications including verification of delay time programming and confirmation of full functionality for detonators. Operational temperature range is -20° to +60° C, and components are packed in water- and shock-resistant cases. Operating range (line-of-sight) is 8,200 feet.

According to Orica, multiple levels of safety and security have been designed into the system including protection against stray signals from RF interference. If severe interference persists, SURBS reverts to standby mode to allow a safe restart. SURBS also has a test mode, which allows prechecking of the strength and quality of the radio signal from potential firing locations. Orica
