Siren warning systems are always customised. No two requirements are the same. Siren warning systems are therefore available in all sizes - from individual sirens, usually for alerting the fire brigade, to regional and nationwide siren warning systems.

A siren consists of the siren horns and the corresponding siren cabinet. Each of our ECN-D electronic sirens has a certain number of horns. The number of horns is determined by the required sound power. This is based on the site planning and a sound forecast. The electronic siren is powered by batteries. This ensures that the siren is operational even if the mains voltage is interrupted.

These electronic sirens are connected to a control centre. Such a control centre is the heart of a siren warning system. It also includes components for monitoring, controlling and triggering the sirens. This can be a touch panel and a triggering option directly on the siren in the siren cabinet, a remote control panel for remote triggering or a software-based monitoring and control station with a connected triggering option. In the case of large siren networks, it often makes sense to have several control centres or several control stations (see "Structure of siren warning systems").
