Systems and methods for controlling addressable combined initiating device and notification appliance circuits

1. An addressable detection and alarm system, comprising:

a combined circuit including paired wires, one or more addressable initiating devices, and one or more non-addressable notification appliances communicatively coupled with the paired wires in parallel; and

a control panel having a controller communicatively coupled with the combined circuit via the paired wires, the controller configured to:

receive, on the paired wires, an indication of an anomaly from an addressable initiating device of the one or more addressable initiating devices;

determine to transmit an alarm signal in response to the indication of the anomaly being received; and

transmit, on the paired wires, the alarm signal to the one or more addressable initiating devices and the one or more non-addressable notification appliances,

wherein a first state of the alarm signal activates the one or more non-addressable notification appliances and deactivates the one or more addressable initiating devices, and wherein a second state of the alarm signal deactivates the one or more non-addressable notification appliances and activates the one or more addressable initiating devices.

2. The addressable detection and alarm system of claim 1 , wherein the controller is further configured to:

monitor the one or more addressable initiating devices while the control panel is in a standby mode;

maintain the one or more non-addressable notification appliances in an off state while the control panel is in the standby mode; and

transition to an alarm mode in response to the indication of the anomaly being received.

3. The addressable detection and alarm system of claim 1 , wherein the controller is further configured to:

monitor the one or more addressable initiating devices in the second state of the alarm signal.

4. The addressable detection and alarm system of claim 1 , wherein the alarm signal is a pulsed signal, and wherein the first state of the alarm signal is a first binary logic state and the second state of the alarm signal is a second binary logic state different from the first binary logic state.

5. The addressable detection and alarm system of claim 1 , wherein the combined circuit is communicatively coupled with the controller at a primary interface via the paired wires, and

wherein the detection and alarm system further comprise a return line communicatively coupled with the combined circuit and the controller at a secondary interface via the paired wires.

6. The addressable detection and alarm system of claim 1 , wherein the one or more addressable initiating devices comprise one or more pull switches or one or more fire detectors.

7. The addressable detection and alarm system of claim 1 , wherein the one or more non-addressable notification appliances comprise one or more visual alarms or one or more audio alarms.

8. A method of controlling, by a control panel, a combined circuit including paired wires, one or more addressable initiating devices, and one or more non-addressable notification appliances communicatively coupled with the paired wires in parallel, the method comprising:

receiving, on the paired wires, an indication of an anomaly from an addressable initiating device of the one or more initiating devices;

determining to transmit an alarm signal in response to the indication of the anomaly being received; and

transmitting, on the paired wires, the alarm signal to the one or more addressable initiating devices and the one or more non-addressable notification appliances,

wherein a first state of the alarm signal activates the one or more non-addressable notification appliances and deactivates the one or more addressable initiating devices, and wherein a second state of the alarm signal deactivates the one or more non-addressable notification appliances and activates the one or more addressable initiating devices.

9. The method of claim 8 , further comprising:

monitoring the one or more addressable initiating devices while the control panel is in a standby mode;

maintaining the one or more non-addressable notification appliances in an off state while the control panel is in the standby mode; and

transitioning to an alarm mode in response to receiving the indication of the anomaly.

10. The method of claim 8 , further comprising:

monitoring the one or more addressable initiating devices in the second state of the alarm signal.

11. The method of claim 8 , wherein the alarm signal is a pulsed signal, and wherein the first state of the alarm signal is a first binary logic state and the second state of the alarm signal is a second binary logic state different from the first binary logic state.

12. The method of claim 8 , wherein the combined circuit is communicatively coupled with the control panel at a primary interface via the paired wires, and

wherein the combined circuit further includes a return line communicatively coupled with the combined circuit and the control panel at a secondary interface via the paired wires.

13. The method of claim 8 , wherein the one or more addressable initiating devices comprise one or more pull switches or one or more smoke detectors.

14. The method of claim 8 , wherein the one or more non-addressable notification appliances comprise one or more visual alarms or one or more audio alarms.

15. A non transitory computer-readable medium storing instructions for controlling addressable detection and alarm system comprising a control panel, a combined circuit including paired wires, one or more addressable initiating devices, and one or more non-addressable notification appliances communicatively coupled with the paired wires in parallel, comprising instructions to:

receive, on the paired wires, an indication of an anomaly from an addressable initiating device of the one or more initiating devices;

determine to transmit an alarm signal in response to the indication of the anomaly being received; and

transmit, on the paired wires, the alarm signal to the one or more addressable initiating devices and the one or more non-addressable notification appliances,

wherein a first state of the alarm signal activates the one or more non-addressable notification appliances and deactivates the one or more addressable initiating devices, and wherein a second state of the alarm signal deactivates the one or more non-addressable notification appliances and activates the one or more addressable initiating devices.

16. The non transitory computer-readable medium of claim 15 , further comprising instructions to:

monitor the one or more addressable initiating devices while the control panel is in a standby mode;

maintain the one or more non-addressable notification appliances in an off state while the control panel is in the standby mode; and

transition to an alarm mode in response to the indication of the anomaly being received.
