Alarm Systems

Signaling

There are lots of types of different alarm systems, doorbell, incoming calls, alarm clocks and others.  They are based on a combination of light, sound and vibration functions depending on its purpose. Vibrating alarm systems can be placed under a pillow, so chosen triggers, like an alarm clock or doorbell, can wake a sleeping person up. Light flash systems can be used to alarm/assist in much larger areas and indicate different messages.
