Abstract

The present invention relates to an electrical circuit for use in an alarm system. The circuit and alarm system being in electrical communication with an electrical power source. The alarm system has a detector configured to generate a first signal and a second signal in response to triggering by an individual. The alarm system further has an announcer adapted to produce an IN announcement in response to an IN signal and an OUT announcement in response to an OUT signal. The circuit comprises a first circuit portion which is responsive to the first signal for generating the IN signal to activate the announcer; and a second circuit portion which is responsive to the second signal for generating the OUT signal to activate the announcer.

Claims

1. An electrical circuit for use in an alarm system, the circuit configured for electrical communication with an electrical power source, such an alarm system having a detector configured to generate a first signal and a second signal in response to triggering by a body, such an alarm system further having an announcer adapted to produce an IN announcement in response to an IN signal and an OUT announcement in response to an OUT signal, the circuit comprising:

a) first means responsive to such a first signal for generating the IN signal to activate such an announcer;

b) second means responsive to such a second signal for generating the OUT signal to activate such an announcer; and

c) switch means for resetting the circuit to a default setting;

the switch means operated externally of the circuit and such an alarm system.

2. The circuit of claim 1, wherein the switch means is manually operated.

3. The circuit of claim 1, wherein the switch means includes two switches.

4. The circuit of claim 3, wherein the two switches are manually operated.

5. An electrical circuit for use in an alarm system, the circuit and alarm system in electrical communication with an electrical power source, the alarm system having a detector configured to generate a first signal and a second signal in response to triggering by an individual, the alarm system further having an announcer adapted to produce an IN announcement in response to an IN signal and an OUT announcement in response to an OUT signal, the circuit comprising:

a) first means responsive to the first signal for generating the IN signal to activate the announcer;

b) second means responsive to the second signal for generating the OUT signal to activate the announcer; and

c) externally operated switch means for resetting the circuit to a default setting.

6. The circuit of claim 5, wherein the switch means is manually operated.

7. The circuit of claim 5, wherein the switch means includes two switches.

8. The circuit of claim 7, wherein the two switches are manually operated.
