Signalers, often referred to as sensors, are designed to be triggered by everyday events, such as the doorbell, the telephone, or a baby cry.  These signalers in turn communicate with remote receivers that turn on and off lamps in your home or a vibrator to alert you to the event that just happened.  Typically, with most receivers, you plug one of your own lamps or vibrator directly into the signaler.  Often, the light on/off pattern will help you identify which sound is present.  There are some remote receivers that have a horn or other audible alerting buzzer, generally around 95 dB, to notify you of the event.

Generally, for complete interaction between sensors and receivers, you must have all sensors and receivers of the same brand.  The only exception to this is some of the he Sonic Alert and Simplicity products do interact together allowing you to mix and match between the lines.  Caution should be used when mixing brands as distance may be reduced.

Things to consider when choosing a signaler:

How big is your home?

You'll want a different type of signaler in a dorm-room than would be needed in a 2-bedroom home.  In smaller  areas, individual signalers (especially with small strobe options) work best.  In multi-room homes, consider remote receivers that allow you to be notified throughout your house.  Some signaling systems are even designed to grow with you, allowing you to add on components as your needs change.

Do you want to choose individual signalers to fit your specific needs or would you prefer an all-in-one system?
