Abstract
Abstract An alarm system remote monitor panel having a series of control units, each unit being provided with a light cell, diodes and a coil so that when a remote sensor triggers an alarm, the light will be illuminated and the audio unit activated. The audio may be disconnected at the monitor panel, and the light turned off at the sensor.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
140 words
An alarm system having a panel board, control units in said panel board, each unit having a sensor activated audio alarm, illuminating means and a sensor mounted in an electrical circuit, a line connected into said circuit and having its terminals mountable in said panel board, each control unit having a transparent plate, and having said illuminating means behind said plate, a switch in said unit having means for manually deactivating said alarm, a shaft extending from said plate to said switch and movable by pressure against said plate to actuate said switch, and circuit directional control means between said switch and said sensor, another line having its terminals in said unit, and having a remote switch closed upon activation of said alarm and illuminating said illuminating means and manually reopened to reset the unit, and deactivate said illuminating means.
Claim 2
Dependent Claim
140 words
An alarm system having a panel board, control units in said panel board, each unit having a sensor activated audio alarm, illuminating means and a sensor mounted in an electrical circuit, a line connected into said circuit and having its terminals mountable in said panel board, each control unit having a transparent plate, and having said illuminating means behind said plate, a switch in said unit having means for manually deactivating said alarm, a shaft extending from said plate to said switch and movable by pressure against said plate to actuate said switch, and circuit directional control means between said switch and said sensor, another line having its terminals in said unit, and having a remote switch closed upon activation of said alarm and illuminating said illuminating means and manually reopened to reset the unit, and deactivate said illuminating means.
Claim 3
Dependent Claim
33 words
The device defined in claim 1 wherein said switch in said units may be opened to deactivate the audio alarm, and said remote switch may be manually opened to deactivate said illuminating means.
Claim 4
Dependent Claim
60 words
The device defined in claim 1 wherein said sensor and said audio alarm means are in one circuit and said illuminating means is in another parallel circuit, said switch in said unit being manually movable to break the circuit to said audio alarm and a remote switch located in the sensor area for breaking the circuit through said illuminating means.
Claim 5
Dependent Claim
32 words
The device defined in claim 1 wherein a testing unit is mounted in said panel board having a manually actuated second switch mounted on said panel board to simulate a remote switch.
Claim 6
Dependent Claim
77 words
The device defined in claim 1 wherein said circuit consist of a line leading from a source of power, directional control diodes in said line maintaining the current flow in one direction only, the other line passing through said remote switch so that the flow of power to the sensor and audio alarm may be broken while the flow through the illuminating means and solenoid will continue until broken by the manual opening of the remote switch.
