Used for Initiating Demolition Charges

The following firing devices used for initiation- of land mines and demolition explosives are also known as detonators (Ref 30a, pp 50-4 Ref 32b, pp 121-27 and Ref 53, pp 34-9) 

1) Concussion Detonator Ml, Delay Type is a mechanical firing device actuated by the concussion wave of a nearby blast. It fires several charges simultaneously without connecting them by wires or detonating cord. A

For its functioning, remove the safety pin and pull the T-ring vigorously in order to draw the coated wire thru flash compn. This ignites the powder-train delay and about 8 seconds later the delay fuse explodes the blasting cap (Ref 30a, pp 47-8 and Ref 32b, 

3) Friction Detonator, 15 Second Delay, Ml (Fig 68) is almost identical to the 8-sec delay detonator in overall appearance and functioning, except that its pull ring is circular and the powder-delay train is of 15-sec duration. (Ref 30a, pp 49-50 and Ref 32b, pp 126-27)
