    摘要: A time delay firing device used for initiating explosives or pyrotechnics ter a preset delay. The unique design allows the device to be used directly in combination with explosives or pyrotechnics or with a variety of accessories. It can be used in conjunction with a standard safety and arming device or with a special blasting adapter for initiating electric caps, or in conjunction with a training adapter for initiating standard pyrotechnics. When used in conjunction with a blasting or training adapter, the device can be refurbished and reset by the user in the field. Furthermore, a self test feature is provided. Time delays in eleven discrete settings from 15 minutes to 72 hours are achieved through the use of a highly stable oscillator coupled to a shift register counting circuit.
