What are Signaling Systems?

Signaling systems, or simply signalers, are designed to help notify you of different events, such as the phone/videophone ringing, the doorbell, a baby's cry, motion, weather alerts, smoke alarms, or carbon monoxide detectors. Also known as alerting or notification systems, these devices can alert you to different events through flashing lights, loud audible alarms, and/or vibration.

There are four things to consider when customizing an alerting system:

1. Transmitters:

Which event do you want to be notified of?

You will need to purchase one transmitter for each event you would like to be notified of. Each transmitter is designed to alert you for a specific event; however, some transmitters do work for more than one event, such as a door and phone transmitter. For example, if you want to be alerted when your phone rings and when baby is crying, you would purchase one phone transmitter and one baby cry transmitter.

2. Receivers

How many rooms do you want to be notified in?

For each room you want to be notified in, you will need to purchase a receiver. For example, if you wanted to be alerted in the bedroom, living room, and kitchen, you should purchase three receivers. Some brands also have portable receivers (such as pagers and watches) that you can bring with you wherever you go in your home. Each receiver will work with all your transmitters, as long as they are the same brand.

3. signaler illustrationsCompatibility

To ensure compatibility we suggest purchasing the same brand of signaling components. Don't mix apples with oranges! For example, if you already own a Sonic Boom SB1000ss alarm clock, buy signalers made by Sonic Alert.

4. Technology

Basically, there are two types of technology available for alerting systems. They can be either:

Radio Frequency (RF) Technology:

This technology sends a signal from your transmitters to your receivers through radio waves. It is ideal for both home use and for people who live in apartments, dorms, or other types of public housing because built-in dip switches can be adjusted to ensure your system will not interfere with a neighboring system. The following brands are radio frequency: Bellman & Symfon, Clarity/Ameriphone, and Silent Call.


Line Carrier Technology:

This technology sends a signal from your transmitters to your receivers through your home's electrical circuits. There is not any specific information about this technology that you need to be aware of. Sonic Alert uses line carrier technology.


Why are signalers so important?

Signaling systems not only allow deaf and hard-of-hearing people become more independent, they may also save lives. Watch the video to your right and see why alerting devices are so important!

At Assistech we carry a wide range of visual, vibrating, and audio signalers for the deaf and the hearing impaired, including the newest T3—or Temporal 3—smoke detector technology.
