Wireless alarm system
First Claim
1. A wireless alarm system activated selectively by a person which comprises:
- a portable wireless transmitter assembly adapted to be concealed on the person, said assembly comprising;
a pressure actuated normally open contact switch adapted to be closed under pressure applied by the person, alerting means activated by the pressure actuated switch for alerting the person by a tactually perceivable signal when said switch is closed, timer means activated by the pressure actuated switch when said switch is closed, a radio transmitter activated by said timer means for transmitting a coded wireless alarm signal on at least one predetermined radio frequency, said timer means activating the radio transmitter a predetermined period of time after the pressure actuated switch is closed, and a battery power supply for the alerting means, timer means and radio transmitter;
a radio receiver and signal decoder for receiving the coded wireless signal transmitted by the radio transmitter;
an adjustable timer and signal relay means connected to the radio receiver for relaying the alarm signal on to personnel alerting means of the alarm system a predetermined period of time after the coded wireless alarm signal is received by the radio receiver; and
