Please note: This is a Sole Source Notification. Specifications include, but are not limited to: The Wyssen Tower Remote Avalanche Control System provides a unique combination of features that make it suitable for the Mount Superior RAC installation project. The Wyssen avalanche tower is designed to trigger avalanches proactively with remote-controlled blasting. To trigger an avalanche, a coded command is sent from the control center WAC.3® to the control system of the deployment box to initiate blasting. Communication with the systems is redundant in that they can operate on both cellular and radio modems and adjacent towers will function as repeaters to relay a signal in the case that one tower loses connection. The deployment box contains up to 12 explosive charges, which can be individually deployed by remote control. When the explosive charge is dropped two igniters are pulled, and the explosion is set off after a time delay. The charge hangs from a cord about 2-3 meters (7-10 ft) above the snow cover, and the cord is dropped after blasting. To reload explosive charges the deployment box is lifted from the tower by helicopter and brought to a workshop or warehouse.
