Abstract
An alarm device having a code verification system is disclosed for registering and transmitting a preselected code to a receiving station. If the preselected code is at the receiving station, no alarm signal will be produced. The code verification system comprises register means under control of an operator for registering a code that is entered therein by the operator. A transmitter is provided which is responsive to a transmit signal for transmitting the contents of the register to the receiving station. A transmitter signal generating means is similarly provided for generating the transmit signal to initiate a transmission. The system further includes a comparator for comparing the code registered in the register with the preselected code and for generating an inhibit signal when the codes are different. Inhibit means is provided which is responsive to the inhibit signal for preventing transmission of the contents of the register.
