• b. an RF transmitter actuable by said first electrical signal to transmit a second electrical signal;
• c. an RF receiver operable to receive said second electrical signal and to generate a third electrical signal in response thereto;
• d. an alarm device operable to generate a visually and/or audibly perceptible signal in response to reception at said alarm device of said third electrical signal;
• e. switch means interposed between said receiver and said alarm device, said switch means having a first state, wherein said third electrical signal passes from said receiver to said alarm device, and a second state, wherein said third electrical signal is blocked from passing from said receiver to said alarm device;
• f. manually operable control means for selectively changing said switch means from said first to said second state;
• and
