Abstract: Emergency room indication systems and methods are provided that, when activated provide a visual indication to first responders to identify rooms in a building where vulnerable victims are located. Emergency room indication systems include a transmitter module and a receiver module. The receiver module is configured to be placed in a window. The transmitter module receives an alarm signal from a smoke detector and sends an activation signal to the receiver module. When the receive module receives the activation signal, it activates an indicator light that may be seen by first responders outside the building.
