ABSTRACT:
A fire alarm and protection enclosure in the form of a booth or box having means therein for signalling an alarm to a fire station and/or police station. The enclosure includes a door and a treadle upon which a person must stand and close the door which is then automatically locked upon actuating the alarm, which door remains locked to detain the person setting off the alarm for a predetermined period. Electrical interlock circuitry interconnected with the door, the treadle and the door lock renders the apparatus fool-proof or tamperproof so that false alarms are prevented.
