Automatic alarm code converter |
摘要 |
An automatic alarm code converter wherein a plurality of alarm dialers report alarm conditions using security industry standard pulsed tone, FSK, or DTMF formats and call through the PSTN to the converter. The converter comprises a telephone line interface/decoder, a microprocessor which correlates the received alarm ID and code with addresses in a page data memory. The page data memory contains a pager number and an associated alphanumeric ASCII message The code converter further comprises a software program embodied in an EPROM which instructs on the automatic formatting of the page data into the PET/TAP protocol. The code converter communicates the page data to the paging system through a full duplex serial port either by direct RS232 connection or remotely through a dial-out modem using the PET/TAP protocol.
