SAFETY
Miss-sequencing: Prevents arming whenever “air flow”
arming conditions precede “set-back”
arming conditions.
Arming Distance: 100m from muzzle.
Double loading: The fuze will not function in bore at a double
loading event.
Shorted Electric
Detonator:
The electric detonator are shorted until arming.
Safety pull wire: No use of safety pull wire.
