Abstract:
1. A system for protecting from fire, premises that include a heat generating appliance connected to a power source, said system comprising: a signal generator means for generating a smoke-on signal in response to the presence of smoke on said premises; a first multiplexor means for generating at an output terminal of said first multiplexor means, a MUX signal corresponding to a selectable mode of three modes of smoke signal input to said first multiplexor; said selectable mode being any one of a.) said smoke-on signal when smoke is detected by a smoke detector; b.) a continuous smoke-on signal; c.) a continuous smoke-off signal; any one of said three modes selected by manually setting a pair of enable switches of said MUX; a memory means for storing a telephone number of a responsible party corresponding to an address of said smoke detector; a first functional controller means connected to said memory means and to an output terminal of said first multiplexer means for generating a combined signal of said MUX signal and said stored telephone number; a first RF transmitter means having an input terminal connected to an output terminal of said first multiplexor means for broadcasting a combined signal being a combination of said MUX signal and said stored telephone number a first RF receiver means having an input terminal for receiving said combined signal broadcast by said first RF transmitter means; a second multiplexor means having an enable terminal connected to said first RF receiver means for receiving said broadcast combined signal; and said second multiplexor means having a first input terminal connected to a hi-on signal; and said second multiplexor means having a second input terminal connected to a low-off signal; said hi on signal being a part of said MUX signal activated when said smoke detector generates said smoke on signal; said low off signal activated when said smoke detector generates no smoke on signal; an ON/OFF solenoid switch means having a control terminal connected to an output terminal of said second multiplexor means; and said ON/OFF solenoid switch means arranged for controlling power to said heat generating appliance; a second RF receiver means for receiving said combined signal from said RF transmitter means; a second functional controller means having an input terminal connected to said second RF receiver means for receiving said combined signal; a third functional controller means connected to a phone dialer arranged to call said stored telephone number to announce a smoke-on signal at said stored address.
