A system for detecting the existence of a hazardous condition in an area includes a number of battery-powered detecting units whereby each detecting unit is respectively located within a zone within the area and each detecting unit includes a sensing circuit, a battery level monitoring circuit and a transmitting circuit. The sensing circuit senses the existence of a hazardous condition within that respective zone and generates a hazardous condition alert signal in response thereto. The battery level monitoring circuit monitors the level of the battery powering the detecting unit and generates a battery status signal when the battery is at an acceptable level. The transmitting circuit transmits the hazardous condition alert signal and/or the battery status signal. The system also includes a receiving unit which is responsive to the detecting units and includes a receiving circuit, a battery status indicating circuit and a hazard condition alert circuit. The receiving circuit receives the hazardous condition alert signals and/or the battery status signals. The battery status indicating circuit is responsive to the battery status signals and includes a number of visual indicators, corresponding to the number of detecting units, which are respectively responsive to the battery status signals such that each indicator provides a first visual indication when the respective battery status signal corresponding thereto is received and a second visual indication when the respective battery status signal is not received. The hazardous condition alert circuit is responsive to the hazardous condition alert signals such that the alert circuit respectively activates the visual indicators corresponding to one of the detecting units when an alert signal is received therefrom. The battery status signals are preferably periodically transmitted by the detecting units to the receiving unit.

DETAILED DESCRIPTION It is an object of the present invention to provide remote detecting systems and methods which overcome the inherent disadvantages of battery-powered detectors which detect the existence of hazardous conditions such as smoke, flames, gases and the like.
It is another object of the present invention to provide remote detecting systems and methods which provide substantial improvement in the reliability of such detectors by utilizing a remote receiver to continuously indicate a battery status of a plurality of detecting units requiring only visual interaction by the user.
It is yet another object of the present invention to provide remote detecting systems and methods which includes a receiver/indicator unit that more directly alerts the user to a hazardous condition.
It is a further object of the invention to provide remote detecting systems and methods which include a receiver having a display that provides valuable information regarding the location of the hazardous condition enabling the user to quickly decide a course of action.
In accordance with one form of the present invention, a system for detecting the existence of a hazardous condition in an area includes at least one battery-powered detecting unit which is located within the area for detecting the existence of the hazardous condition.
The battery-powered detecting unit generates and transmits a battery status signal in response to the battery being at an acceptable level.
Further, the system includes at least one receiving unit which is responsive to the battery status signal such that the receiving unit provides at least one sensory indication when the battery status signal is not received.
In this manner, the status of the battery is passively and continuously monitored thereby relieving an owner of the task of activating a test procedure himself.
In a preferred embodiment, the system includes a plurality of battery-powered detecting units (e.
g.
, four) which are respectively located within a plurality of zones within an area (e
