A detonator (10) is equipped with an input lead (29) having multiple signal transmission lines (30, 31) which provide redundant initiation signals to th e target charge (14) of a detonator (10, 10') thereby increasing the reliabili ty of initiation. The multiple signal transmission lines (30, 31) may be made o f shock tube and can be part of a long or short input lead (29, 129) and may b e initiated by any suitable means, for example by being disposed in signal transmission relation to a detonating cord (60, 62) to improve the reliabili ty with which a signal is transferred from the detonating cord (60, 62) to the detonator (10, 10').
