Abstract

An alarm system includes a first alarm indicator and a circuit configured to detect an indicator from the first alarm indicator and to generate a signal n response to activation for the first alarm indicator. The alarm system may also have a second alarm indicator configured and arranged to receive the signal from the circuit to activate the second alarm indicator.

Claims

1. An alarm system, comprising:

a first alarm indicator;

a circuit that is configured and arranged to detect an indicator from the first alarm indicator and to generate a signal in response to activation of the first alarm indicator; and

a second alarm indicator that is configured and arranged to receive the signal from the circuit to activate the second alarm indicator.

2. The alarm system of claim 1 wherein:

the first alarm indicator is a first siren and the indicator is a sound from the first siren; and

the circuit is a sound activated circuit that is configured and arranged to detect the sound from the first siren.

3. The alarm system of claim 2 wherein the second alarm indicator is a second siren that is configured and arranged to receive the signal from the sound activated circuit to activate the second siren.

4. The alarm system of claim 2 wherein the second alarm indicator is a strobe that is configured and arranged to receive the signal from the sound activated circuit to activate the strobe.

5. The alarm system of claim 2 wherein the second alarm indicator is a combined siren and strobe that is configured and arranged to receive the signal from the sound activated circuit to activate the strobe.

6. The alarm system of claim 2 wherein the sound activated circuit includes a microphone that is configured and arranged to detect the sound from the first siren.

7. The alarm system of claim 1 wherein:

the first alarm indicator is a first strobe and the indicator is a light from the first strobe; and

the circuit is a light activated circuit that is configured and arranged to detect the Tight from the first strobe.

8. The alarm system of claim 7 wherein the second alarm indicator is a second strobe that is configured and arranged to receive the signal from the light activated circuit to activate the second strobe.

9. The alarm system of claim 7 wherein the second alarm indicator is a siren that is configured and arranged to receive the signal from the light activated circuit to activate the siren.

10. The alarm system of claim 7 wherein the second alarm indicator is a combined siren and strobe that is configured and arranged to receive the signal from the light activated circuit to activate the combined siren and strobe.

11. The alarm system of claim 7 wherein the light activated circuit includes a photodetector to detect the light from the first strobe.
