The Watt Stopper announces its new Telephone Switch Module (TSM). An option with lighting-control panels, the TSM turns a touch-tone phone into a lighting-control switch. When calling the designated TSM number or extension from any phone, voice prompts guide the caller to control lighting on, off or override. Users also can adjust settings, including a passcode feature for added security. The TSM can control five independent light zones when used with a hardwired lighting control panel.
