Remote initiator for the remote initiation of explosive charges

A remote initiator for the remote initiation of explosive charges, the remote initiator includes:

• (i) a transmitter having means for generating and transmitting a coded signal and input means for inputting operational commands into the transmitter for generating the coded signal,
• (ii) at least one receiver adapted to be connected with the explosive charges, the receiver having means for receiving the coded signal from the transmitter and input means for inputting operational commands into the receiver for generating an output signal for the remote initiation of explosive charges upon receipt of a valid transmitted coded signal in communication with the receiver,
• (iii) a power source for each of the transmitter and receiver, and
• (iv) dual processing means that are independent of each other are adapted to provide independent control of a firing circuit and adapted to synchronise with each processing means before initiation can occur so as to enhance safety and reliability of the transmitter and receiver and the initiation of the remote initiator,
• wherein the transmitter and receiver share and store a common signalling code that binds both the transmitter and receiver to a group and the receiver will only respond to a transmitted coded signal that matches all parts of the common signalling code stored in the receiver.

A remote initiating system for the remote initiation of explosive charges, the remote initiating system includes a remote initiator including:
