ABSTRACT:
An improved retrofit wireless remote nurse call apparatus requiring no system conversion or structural adaptation uses battery power and decretive water resistant call buttons with electronic key for selective response that are both functional and inexpensive. The transmitter and receiver are pre-paired thus requiring no on site programming. The receiver plugs into existing call button wall jack. Options include parallel operation with existing call buttons plugged into the receiver and battery recharging.
