Abstract
Fire alarm device disposed within a booth having a door, the fire alarm device being operable only when the door of the booth is closed by the person operating the device. Upon the actuation of the fire alarm, the door of the booth is locked for a predetermined length of time, and a signal light visible outside the booth is actuated so as to alert passers-by and/or policemen to the fact that the fire alarm has been pulled. The time delay period during which the person operating the alarm is confined in the booth is sufficient to prevent his making an immediate get-away. This increases the chances of his being caught, should the alarm be a false one, after the door has again been permitted to open to release him from the booth. It also encourages the alarm operator to remain in the vicinity of the alarm box, when the alarm is legitimate, so that he may direct the fire apparatus to the fire.
