  • Patent number: 4928299
    Abstract: An event monitoring system for payphones is described. Particularly, an arrangement for monitoring events such as the removal of the front cover, vault door and coin box is described. Sensors attached to brackets generate signals indicative of front cover, vault door and coin box removal are sensed by a monitoring circuit and sent to a central telephone office as appropriate. The brackets allow easy mounting of the sensors using existing payphone housing hardware, surfaces and cutouts. Consequently, this mounting arrangement may be used to retrofit standard payphones using only pre-existing mounting locations and holes to include event monitoring capability. The sensors and monitor circuit operate on low power and may be designed to operate in the absence of payphone power.
