Description
The Trip Flare M49 has the same uses as the Parachute Trip Flare M48.
The flare has a grenade shaped cylindrical body, with a nose fuze that protrudes 0.875-inch from the head end. A mounting bracket and a spring-loaded trigger mechanism arc mounted on a metal base cap. The upper arm of the trigger is attached to a trip wire, and the lower arm of the trigger restrains the safety lever after the removal of the safety pin.
Functioning
A pull on the trip wire rotates the upper trigger arm away from the fuze lever. If the trip wire is cut, the upper trigger arm, which is restraining the fuze lever, rotates away from the fuze lever but in an opposite direction from above. A grenade-type fuze is used, but it has no delay element. The fuze ignites the flare instantaneously.
