Abstract
There is disclosed a multi-flashlamp article capable of providing both highly intense audible and visual signals. The article is ideally suited for use as an intrusion alarm and includes a combustible member within the assembly's light-transmittable housing. A prestressed spring actuates the combustible by deforming a tubular primer having a quantity of fulminating material therein. This deflagrating material ignites a second quantity of fulminating material within the combustible's container to effect a suitable audible signal.
