Abstract

Systems and methods for measuring and modifying an input voltage provided to a control panel are provided. Some systems can include measuring the input voltage provided by a power supply, determining whether the input voltage is within a range of acceptable input voltages, transmitting, to the power supply, a modulated signal on a direct current line between the power supply and the control panel instructing the power supply to modify the input voltage, and generating a notification when the input voltage is outside of the range of acceptable input voltages.

Claims (43)

1. A method comprising:

receiving an input voltage from a power supply at a control panel of a security system;

measuring the input voltage from the power supply at the control, panel;

determining, at the control panel, whether the input voltage from the power supply is within a range of acceptable input voltages for powering the control panel;

when the input voltage from the power supply is outside of die range of acceptable input voltages for powering the control panel, generating a notification at the control panel; and

when the input voltage from the power supply is outside of the range of acceptable input voltages for powering the control panel, transmitting a modulated signal from the control panel to the power supply on a direct current line between the power supply and the control panel instructing the power supply to increase or decrease the input voltage from the power supply,

wherein the power supply is installed at a fuse box within a secured area or at a wall outlet within the secured area.

2. The method of claim 1 wherein the notification includes a pop-up window displayed on a display device of the control panel.

3. The method of claim 2 further comprising:

generating step-by-step instructions to increase or decrease the input voltage from the power supply to be within the range of acceptable input voltages for powering the control panel; and

displaying the step-by-step instructions in the pop-up window.

4. The method of claim 1 wherein the direct current line comprises wiring between the control panel and the power supply.

5. The method of claim 4 wherein the wiring includes preexisting wiring in the secured area.

6. The method of claim 1 further comprising enunciating the notification through a speaker of the control panel.

7. The method of claim 1 further comprising activating a trouble indicator associated with the control panel to visually display the notification.

8. A method comprising:

receiving an input voltage from a power supply at a control panel of a security system;

measuring the input voltage from the power supply at the control panel;

determining, at the control panel, whether the input voltage from the power supply is within a range of acceptable input voltages for powering the control panel; and

when the input voltage from the power supply is outside of the range of acceptable input voltages for powering the control panel, transmitting a modulated signal from the control panel to the power supply on a direct current line between the power supply and the control panel instructing the power supply to increase or decrease the input voltage from the power supply,

wherein the power supply is installed at a fuse box within a secured area or at a wall outlet within the secured area.

9. The method of claim 8 wherein the modulated signal includes a single hit, digital signal that indicates whether the power supply should increase or decrease the input voltage from the power supply.

10. The method of claim 8 wherein the modulated signal instructs the power supply to increase or decrease the input voltage from the power supply by a predetermined amount.

11. The method of claim 10 wherein the predetermined amount is 100 mV.

12. The method of claim 8 wherein the modulated signal includes a multiple bit, digital signal that indicates whether the power supply should increase or decrease the input voltage from the power supply and an amount by which the power supply should increase or decrease the input voltage from the power supply.

13. The method of claim 12 further comprising generating the multiple bit, digital signal via a plurality of modulations on the direct current line.

14. The method of claim 8 further comprising generating a notification to display on a display device of the control panel indicating a failure to increase or decrease the input voltage from the power supply to be within the range of acceptable input voltages for powering the control panel.

15. The method of claim 14 further comprising:

generating step-by-step instructions to increase or decrease the input voltage from the power supply to be within the range of acceptable input voltages for powering the control panel; and

displaying the step-by-step instructions on the display device.

16. A system comprising:

a power supply;

a control panel; and

a direct current line coupled between the power supply and control panel,

wherein the control panel receives an input voltage provided by the power supply,

wherein the control panel measures the input voltage provided by the power supply,

wherein the control panel determines whether the input voltage provided by the power supply is within a range of acceptable input voltages for powering the control panel, and

wherein, when the input voltage from the power supply is outside of the range of acceptable input voltages for powering the control panel, the control panel transmits a modulated signal to the power supply on the direct current line instructing the power supply to increase or decrease the input voltage provided by the power supply, and

wherein the power supply is installed at a fuse box within a secured area or at a wall outlet within the secured area.

17. The system of claim 16 wherein the modulated signal includes a single bit, digital signal that indicates whether the power supply should increase or decrease the input voltage provided by the power supply.

18. The system of claim 16 wherein the modulated signal instructs the power supply to increase or decrease the input voltage provided by the power supply by a predetermined amount.

19. The system of claim 18 wherein the predetermined amount, is 100 mV.

20. The system of claim 16 wherein the modulated signal includes a multiple bit, digital signal that indicates whether the power supply should increase or decrease the input voltage provided by the power supply and an amount by which the power supply should increase or decrease the input voltage provided by the power supply, and wherein the multiple bit, digital signal is generated via a plurality of modulations on the direct current line.
