Bomb Alarm System
The Bomb Alarm System (also known as the Bomb Alarm Display System) was a US and UK network of optical bhangmeter sensors intended to confirm the detonation of an enemy nuclear weapon near cities or military installations within the US or at US operated early warning radar sites in the UK DEW Line, or Greenland. The BAS was designed by Western Union in 1959 and was in full operation by 1962. The BAS was the responsibility of the 9th Space Division. The BAS operated until 1967. The BAS sensors were designed to report the occurrence of a nuclear flash via telephone or telegraph lines before the sensor was destroyed by the explosion. They were designed to ignore spurious signals from lightning, sunlight, or electrical surges.

Bomb Alarm System Sensor
A bomb is an explosive weapon that uses the Exothermic process, exothermic reaction of an explosive material to provide an extremely sudden and violent release of energy. Detonations inflict damage principally through ground- and atmosphere-transmitted mechanical stress (mechanics), stress, the impact and penetration of pressure-driven projectiles, pressure damage, and explosion-generated effects. Bombs have been utilized since the 11th century starting in East Asia. The term bomb is not usually applied to explosive devices used for civilian purposes such as construction or mining, although the people using the devices may sometimes refer to them as a "bomb". The military use of the term "bomb", or more specifically aerial bomb action, typically refers to airdropped, unpowered explosive weapons most commonly used by air forces and naval aviation. Other military explosive weapons not classified as "bombs" include shell (projectile), shells, depth charges (used in water), or lan ...
