This signal is used for activation and telemetry of all units in a network.<br /> <br /> The modem can be used in tandem with Federal Signal&#039;s Commander Digital System (aka SFCDware).<br /> <br /> This protocol is commonly found among their line of mass warning and notification appliances. It is often heard over public safety/fire/police radio to control warning sirens. The entire system can be configured to transmit daily at a user-defined time to poll health checks on units in the system or manually commanded to activate or deactivate one or more nodes within a system. The protocol may also be used to remotely upgrade or program units if desired.<br /> <br /> == Specifications ==<br /> <br /> * 2FSK Minimum Shift Keyed modulation<br /> * Mark: 1200Hz<br /> * Space: 1800Hz<br /> * Baudrate: 1200 baud<br /> * Error Correction: CRC16/XMODEM (poly 0x1021)<br /> <br /> == Hardware ==<br /> For command and control, the Federal Signal SS2000+ encoder is typically used to interface with SFCDware and control various nodes within a system (be it Informer radios, FC controllers, or more). This device can be used standalone or attached to a PC running SFCDware for a graphical interface to a siren system. There is also a cut-down version called the Modem-MSK which will only work with a computer attached. This unit is also used in their mobile activation case (MAC-1/2)<br /> <br /> == Decoding Software ==<br /> If you want to set up your own siren in SimTX you may ask @null_0xf4 in discord.<br /> <br /> == Video Examples ==<br /> <br /> * [https://www.youtube.com/watch?v=Y-L0i6jNB8w Demo of the SS2000+ encoder]<br /> <br /> == Additional Links ==<br /> <br /> * [https://www.fedsig.com/product/fc-siren-controller/ Federal Signal&#039;s most popular controller, the FC]<br /> * [https://www.fedsig.com/product/informer-tone-alert-radio/ An indoor notification appliance that can also be controlled via Federal Digital]<br /> * [https://www.fedsig.com/product/ss2000-series-c-local-hardware-activation-point SS2000+ product page]</div>
