Electronic mass notification siren ATIHPSS32
The electronic siren is a series of appliances and circuit boards that are together capable of generating warning sounds and voice over large areas. These signals mimic the sounds made by an electromechanical siren. Connecting these circuits together with a set of batteries, allows the necessary sounds to be generated authentically and with a minimum amount of energy.
The system is designed around a CLASS D amplifier that is protected by a patent held by the American manufacturer ATI SYSTEMS. A microcontroller is also used allowing programming specific to the customers needs.
The siren represents a new method of design, whereby the generator, the amplifier and the controller are all on one board. This greatly reduces the amount of wiring needed and improves the reliability of the unit. Communications ports such as RS232 and RS485 are also included as standard.
Power is supplied by a bank of four 12V/75AH batteries that output 24V to the sirens. The batteries are charged by a 10A charger or alternatively by a solar charger. All the elements are mounted inside a NEMA 4X stainless steel enclosure, securely protecting from any outdoor elements.
The use of CLASS D technology ensures maximum usage of the energy available (approx. 95%), that allows low currents to be drawn from the batteries and improves their lifetime.
