Signalling 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.
Technical background

Visual Signalling 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.
Technical background

Audible Signalling Equipment

Acoustic signalling 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 signalling equipment from another is its volume, tone and frequency.
Technical background

Ex-proof Signalling Equipment

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

Degree of protection

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.
Technical background

Standards and certification marks

There is a range of standards and certification marks applicable to industrial products, providing information about their approvals and which regulations they fulfil.
