What are the different types of electrical sirens?

There are several types of electrical sirens available, including: Single-tone sirens: These sirens produce a continuous, single-frequency tone. They are commonly used in applications where a simple, continuous alarm signal is required. Multi-tone sirens: These sirens are capable of producing multiple tones or sequences of tones. They offer more versatility in terms of sound patterns and can be used to convey different types of warnings or messages. Programmable sirens: These sirens allow for customization of the sound patterns and sequences. They can be programmed to produce specific tones, intervals, or patterns according to the application requirements. Wireless sirens: These sirens are wirelessly connected to a control panel or a central alarm system. They offer flexibility in installation and can be easily integrated into existing security or alarm systems.
