An alarm system comprising: a) multiple alarm devices including an alarm clock, a telephone, and a door bell, each alarm device including means for generating an alarm signal, and a transmitter connected to each said generating means for transmitting an alarm signal at a frequency different for each of said alarm devices and selected users so that each alarm device issues a different frequency signal for each selected user; b) a silent notification device comprising a vibration module for each of said users including a receiver for receiving an alarm signal at a selected frequency unique to a specific user and to a specific alarm device and means in each notification device for alerting a user that said notification device has received an alarm signal from a particular alarm device, each notification device receiving alarm signals from more than one alarm device so that each user receives alarms signals from different alarm devices; and c) each said vibration module being selectively programmable by a user to change individually the intensity of either a light pulse or a strong pulse and a pattern of the vibrations comprising one of a continuous pulse short intermittent pulses, long intermittent pulses, or long/short intermittent pulses to indicate to a user which alarm device is issuing the alarm signal; and d) each said vibration module is mounted on a wrist band worn by a user.
