Abstract
An alarm device for night deposit boxes consists of a housing with a tear gas or dye-releasing alarm in a housing mountable inside the deposit box. The housing includes electrical circuitry, which is connected by a flexible conductor cable to a trigger switch fitting into a magnetic keeper. The keeper is mechanically connected to the deposit box door assembly by a flexible cable. The circuitry includes a key-operated disabling switch and a light-emitting diode which is momentarily energized through a capacitor when the circuit is enabled.
