Timers

EXPLOSIVE INITIATION SYSTEM

TIMERS

Timers are one of the most common methods of explosive initiation. In popular culture, the ‘Time-Bomb’ was the face of any type of warhead initiation. Historically, the first evident use of a timer for explosive initiation goes back to 1776, when at New York Harbor, the event known as Turtle submarine attack on the Eagle happened. Since then, there has been a rapid advancement in the technology of timer systems. 

Before the advent of Electronic Integrated Circuits, mechanical timers were most widely used. They are still in use, but now electronic timers in various forms reign the complete domain which is our core area of expertise. Our Smart Explosive Initiation Systems Development Vertical, under the Advanced Weapon System Development Division, has evolved as the birth place for a range of world-class, intelligent explosive initiators.

"With the use of best available technologies, smart design approaches and user-friendly functionalities, these timers have emerged as one of the most sought-after systems by Indian Armed Forces units - specifically units deployed in Counter-Terrorism/Insurgency (CT/CI) operations. We have created several safety measures including a Safety plug to avoid accidental fire, separate units for processing and firing, safety logic sequence to prevent wrong commands, and a mechanism to prevent the execution of any operation down to the last second.
All the developed versions have gone through extensive functional and field trials at various operational areas. They are compatible in all terrain and weather and have also passed all required environmental tests"
