Central station alarm
First Claim
1. An alarm apparatus operating within a predetermined set of operating parameters comprisingfirst input means adapted to receive at least one signal representative of the status of an alarm sensor,second input means for entering changes to said operating parameters other than actuating or deactuating said alarm apparatus,sequencing means responsive to said first and second input means for generating signals representative of the status of at least one alarm sensor and the changes received from said second input means, andtransmitting means for communicating to a central alarm station the status of the at least one alarm sensor together with the changes to system operating parameters.

Abstract
A plurality of remotely located transponder units each communicate with a central station unit to provide a full array of alarm and status signals to the central station. The transponder units are capable of remotely addressing the central station unit directly, without the need for human intervention at the central station, to alter subscriber opening and closing times, passwords, and other system parameters. The transponder also permits defective zones to be shunted either from the central station or locally pending repair, testing and status checks.

1. An alarm apparatus operating within a predetermined set of operating parameters comprising
first input means adapted to receive at least one signal representative of the status of an alarm sensor, second input means for entering changes to said operating parameters other than actuating or deactuating said alarm apparatus, sequencing means responsive to said first and second input means for generating signals representative of the status of at least one alarm sensor and the changes received from said second input means, and transmitting means for communicating to a central alarm station the status of the at least one alarm sensor together with the changes to system operating parameters.

2. A method for communicating a change in system operating parameters, other than actuating or deactuating the subscriber system, in a subscriber system of a central station alarm system .Iadd.capable of transmitting alarm inputs .Iaddend.comprising the steps of
entering in the subscriber system a change in said system operating parameters other than actuating or deactuating the subscriber system, transmitting the change in system operating parameters to the central station in the same manner as is used to transmit alarm inputs, and altering the system operating parameters stored in the central station to correspond to the changes entered in the subscriber system without action by an operator of the central station.
