What is the realistic service life of an electronic siren system?
• A strong loudspeaker constructed of heavy-duty metallic projector horns and a robust galvanized steel-supporting pole should provide a service life of 20 years. • The electronics: amplifiers – signal generator – communication interfaces, if protected inside a weatherproof enclosure will provide at least 10 years fault free service. • Newer technologies in control and communication may dictate an upgrade in parts of the electronic system at the end of this 10-year period.
