I need to find a wall-mounted 277V, 20A light switch that can also be controlled by a low-voltage signal. Basically, we need to be able to turn a certain set of light switches in an office building on remotely when there is an alarm condition, regardless of the switch being 'on' or 'off.' I know this can be done using sensing shunt relays (like UL 924), but I'm hoping for a retrofit, all-in-one solution that will fit in an old-work switch box. Does anyone know of a product which can accomplish this *without* the need for external relaying or an elaborate workaround? The emphasis here is cost reduction. If I can pull just one 24V wire, so much the better.
Have you looked in to the X10 remote system? If it wireless rather than low voltage, but that is even better. It also can be used on multiple switches for lights in different rooms. Also a phone dialer as part of an alarm system.
