Abstract: Emergency lighting system with alarm for fire, gas and ambient air pollution with automatic monitoring and battery recharging utilizing a bus and a microprocessor circuit whose input and output signals regulate the programming. A sensor for one or more environmental hazard factors is connected to the data bus.

Abstract: A self-contained apparatus for emergency lighting has a light, a detector for gas or the like, which can produce an electric input, and a processor which can receive the electric input and produce an optic and/or acoustic alarm.

Abstract: This invention relates to an improvement in systems for the rapid attachment of lamps, especially lamps having a watertight housing, whereby a lamp may be connected in a single simple operation to its housing, a supporting plate previously attached to the ceiling (or a wall) and at the same time to a source of power, by means of suitable electrical connectors, forming an enclosed watertight unit in accordance with the applicable regulations.

Abstract: An emergency lighting system of an advanced type which, through the use of an appropriate microprocessor, can be used to check the recharging current and voltage of the batteries and detect faults in the circuit and the fluorescent or incandescent lamps, with the programming and performance of a functional test over a programmable period, with a visual display and the programming and performance of an independence test at programmable intervals. The results of the periodical fault tests and the independence test are communicated to a centralized control and monitoring unit which can be activated remotely and is also capable of receiving and transmitting operating orders to the individual emergency units. A microprocessor circuit for performing the periodical functional test on the connected lamps, and for programming and performance of the independence test at programmable intervals, providing an indication of defective lamps and deactivating one or more lamps, is included in the battery unit.
