Monitored voltage inverter for security system
View Patent ↗A monitored voltage inverter for a security system is disclosed. A voltage inverter is coupled to the power supply of the control panel which can provide AC power to the network hardware devices. The voltage inverter converts the DC voltage of a back-up power supply to household or commercial AC current. In a preferred embodiment, the voltage inverter is mounted on the printed circuit board and is coupled to the network hardware devices.
