Multiple-triggering alarm system by transmitters and portable receiver-buzzer

A transmitter/vibrating receiver system that discreetly warns one or several people, at a distance, said system comprising:

• plural transmitters that include (a) a central transmitter box with at least a first LED, (b) at least one presence detector transmitter box with a presence detector, a receiver, a LED, and a light, (c) a telephone plug transmitter box responsive to a telephone call to send a signal and (d) a front door transmitter box responsive to action at a front door to send a signal;
• and
• at least one portable vibrating-receiver box that receives a respective signal from at least one of said plural transmitters,
• said at least one portable vibrating-receiver box having a receiver, a rechargeable battery and at least two LEDs, a respective one of said at least two LEDs denoting which one of said plural transmitters is sending a signal,
• said central transmitter box having an ALARM push button that manually triggers a first coded signal sent by said central transmitter box to the receiver of the portable vibrating-receiver box, said coded signal turns ON a vibrator-motor of the portable vibrating-receiver box and triggers a corresponding one of said at least two LEDs of the portable vibrating-receiver box,
• said first LED of said central transmitter box indicating that an order from the ALARM push button was sent out correctly by the central transmitter box and registered by the receiver of the portable vibrating-receiver,
• wherein said central transmitter box further comprises a housing, said portable vibrating-receiver box being releasably connectable by two contacts to said housing to charge the battery of the portable vibrating-receiver box,
• wherein said central transmitter box further comprises a push button that activates or deactivates the presence detector at a distance with a second coded signal sent by the central transmitter box to the receiver of the presence detector transmitter box, the LED of the presence detector transmitter box lighting-up when the presence detector is in operation, and
• wherein whenever a presence is detected, the presence detector lights-up the light of the presence detector transmitter box and activates the presence detector transmitter box to send a third coded signal to the receiver of the portable vibrating-receiver box, said third coded signal turns ON the vibrator-motor of the portable vibrating-receiver box and triggers a respective LED of the portable vibrating-receiver box.
