Abstract
A power over data cable system has a power controller. The power controller receives alarm signals from alarm systems such as fire alarms and security alarms. The power controller is connected to power over Ethernet switches or injectors (PoE). The PoE Ethernet switches or injectors are coupled network devices, such as door locks, security cameras, etc. When an alarm occurs, the power controller can turn off the power to the network devices by sending a disable signal to an associated PoE Ethernet switch or injector. A user interface, allows a user to easily define which PoE Ethernet switches or injectors are to be opened for a given alarm. Using this system the user can easily setup a system to selectively disable power to certain devices and not others whenever an alarm is activated.
