Remotely programmable, vandal-resistant voice communications unit |
摘要 |
A vandal resistant, remotely programmable voice communications unit is capable of being programmed for automatically calling predetermined telephone numbers. The unit is programmed remotely from any touch-tone telephone. A vandal-resistant push-button actuator employs first and second axially spaced apart, slidable seals on a push-button mounted within a housing. The seals absorb transverse blows to a raised portion of the push-button and a lubricant is disposed between the seals to prevent an adhesive inserted by a vandal from disabling the actuator. A speaker and microphone baffle utilizes offset passageways to inhibit the introduction of a pointed object therethrough to prevent damage to the speaker or microphone. A raised push-button actuator is disposed inwardly of an escutcheon and shaped to form a concave, ring-shaped surface therewith, thus to inhibit damage to the inner surface of the escutcheon from a hammer blow. A vandal-resistant pole mounting device clamps about the pole and is fastened by means of a fastener enclosed within a vandal-resistant housing, thus to prevent tampering with the fastener by a vandal in order to prevent removal of the housing and the mounting device from the pole.
