Radio controlled home security system
First Claim
1. A security system for a home comprising:
- a radio system having a receiver means and a portable transmitter, the transmitter having means for emitting a coded signal and the receiver means being responsive to the coded signal for producing an output,a toggle circuit responsive to the receiver means output to change between a first and a second state,an alarm circuit,means coupled to the toggle circuit and the alarm circuit for arming the alarm circuit when the toggle circuit is in the first state and disarming the alarm circuit when the toggle circuit is in the second state,an electrically operated door striker,means coupled to the door striker and the toggle circuit for releasing the striker when the toggle circuit is in the second state, anda motion detector coupled to the alarm circuit and effective when the circuit is armed to activate the alarm upon detection of motion.

Abstract
A security system has a wall mounted assembly for installation adjacent an entry door and includes a motion detector for sensing intruders, an alarm for sounding a warning, an alarm circuit, a radio receiver responsive to two codes, and an electric door striker. A portable miniature transmitter has two transmission codes to activate the receiver, one for toggling the alarm circuit between armed and disarmed condition and for releasing the door upon disarming the alarm circuit. When the circuit is armed the motion detector is able to activate the alarm. The second transmission code activates the alarm if the circuit is armed. Remote self contained motion detector and transmitter units for use in other rooms use the second code to activate the alarm when motion is detected by those units.
