The LightLEEDer Voice Prompted DTMF Telephone Control module can be added to any panel to provide control from your touch-tone telephone. Voice prompts and telephone DTMF signals (telephone button activations) can control relays, groups, or presets ON or OFF and retrieve current status. Any standard telephone, digital telephone, or cell phone can be used for a switch station. Multiple modules can be installed into a single panel. An optional DTMF Gateway is available that gives a single point connection for network wide control and status.
