Technical information

Signaling equipment generates light and/or sound-based signals, attracting attention as a result. The signal beacons, sirens, horns and buzzers that it uses highlight sources of danger and risk, ensuring that both people and machines stay protected.

Visual Signaling Equipment

There are three factors that determine how bright a warning or signal beacon is: the type of beacon, the colour and the luminous intensity. In turn, this dictates how effective the beacon is and where it can be used.

Audible Signaling Equipment

Acoustic signaling equipment includes electronic sounders such as multi-tone sirens and piezo buzzers, as well as electromechanical sounders such as horns and bells. Generally speaking, what differentiates one piece of acoustic signaling equipment from another is its volume, tone and frequency.


Explosion-proof signaling equipment, also known as Ex signaling equipment or ATEX equipment, provides protection against ignition or explosion in the event that a piece of signaling equipment misfires. It is used in industrial atmospheres that are highly flammable, combustible or at risk of explosion. Ex signaling equipment certification; ATEX classification.

Product standards and markings

Degrees of protection are standards that provide information about the level to which electrical equipment is protected against the effects of solid foreign objects and against the ingress of liquids through the casing or cover.
