This all-in-one signaler lets you know when the telephone is ringing or when someone is at the door by flashing a plugged in lamp or Add-On Strobe. It can also signal Remote Receivers which flash lights in other rooms. Unique flash patterns help you identify which sound is occuring. This signaler is ideal for people who want a cost-effective way to be signalled to both the telephone and the doorbell.
Installation is easy with this wireless signaler. Simply install the wireless doorbell button (included). Or, if you already have a doorbell system, simply connect a few simple wires to the included transmitter.
