Abstract

The invention consists in an alarm signalling device, such as siren or flash light, fed by a solar panel that maintain also the load level of the back up battery, enabling a very long autonomous working. Particularly suited to outdoor signalling devices which are wireless linked to electronic security system. It also checks the solar panel performance and indicates eventual failures.

Description

ALARM SIGNALLING DEVICE POWERED BY A SOLAR PANEL
DESCRIPTION
0 TECHNICAL FIELD: electronic security plants.
0 BACKGROUND ART: the wireless outdoor signallers, as sirens, are at the moment fed by batteries that need periodically to be changed or extracted for the reload.
D DISCLOSURE OF INVENTION: it combines to the signaller , as a siren or a flash light, a solar panel foreseen to feed it and maintain its back up battery load level. Avoiding like this manual intervention for the battery change and increasing the autonomy of the signaller. The working mode of a siren connected to a security system consists in short periods of the signalization actuation, where the battery supplies great part of the energy, and in long periods of silence, where the electrical consumption is reduced and where the solar cell is able to supply the requested energy and to maintain the load level of the battery. This last one, working less, will execute less load/unload cycles and then will last longer. For the requested power, a photovoltaic panel of little dimension, like the ones of the siren box, is enough. The invention checks also the minimum performance, fault or absence of the solar panel and, in case of failure, indicates it to the security system to which it is connected.
D BRIEF DESCRIPTION OF DRAWINGS: figure 1 represents a bloc diagram of the invention. In particular, the group fig.1(1) represents the inside of the siren box, the part fig.l (2) is the photovoltaic module connected to the battery , fig.1(3), for reloading, and , together with this last one, to the electronic module, fig.1(4), for feeding. This one is connected to an electronic security system , for instance through radio frequency (RF) electromagnetic waves using the antenna, fig.1(6). It commands the acoustic actuator, fig.1(5), through a dedicated output. It also checks the current supplied by the solar panel for the minimum performance test.
D BEST MODE FOR CARRYING OUT THE INVENTION: a solar panel of 1,2 Watt with a tension of 12 Volt is integrated in a wireless outdoor siren box. The siren has a 12 Volt reloadable backup battery. It needs a power of 24 Watt to supply an acoustic level of 129 decibel for a maximum lasting of 4 minutes every activation. It will consume in idle a current of 20 milliampere. Preferably, a panel at each side of the container is placed to have a better exposure to the sun rays. For the performance test, the siren should check every 24 hours period that the minimum current has been supplied by the solar panel for at least 5 hours.
0 INDUSTRIAL APPLICABILITY: sirens or flash lights or both linked to electronic security plants.
