Autodialler alarm

Autodialler alarms have some kind of push button transmitter which you carry around with you so that you can call for help from wherever you are in the home. These portable transmitters send a signal to the alarm unit. The transmitter is designed to be worn around the neck, on your wrist or clipped onto your clothing. Some brands offer additional methods of setting off the alarm e.g, a push button on the alarm unit itself, wall buttons or pull cords. Some alarms will go off automatically if they detect smoke, an intruder, a low room temperature or if the user has not been moving around for a while.

Once the button has been pressed, the alarm unit will automatically contact a relative or friend or a special control centre. With most alarm systems it is possible for the person who answers the call to hear and talk to you, although this is not necessary as the alarm has been raised by just pushing the button.

If the alarm has contacted a control centre then your details will automatically appear on a screen in front of the operator. They will usually try to speak to you, often via an intercom channel that is opened up when the alarm is activated, and if you need help, or they cannot get a reply then they will arrange for someone to visit.

An alarm which dials directly through to a relative's or friend's house will usually be programmed to dial more that one number, to increase the chances of finding someone at home

It´s different from alarm autodialler, a part of the wall alarms.
