ADT’s reminder about new standard for visual alarm devices
ADT is reminding the industry that it is now mandatory to conform to the requirements for visual alarm devices in the standard EN54-23. The standard came into effect at the start of 2014 and ensures for the first time that a minimum lux output is achieved within a stated area. The standard covers planning, design, installation, commissioning and service. A minimum light level of 0.4 lx is stipulated on any surface, and manufacturers must specify the room size their product will cover with this level of illumination.
The standard also requires the colour of the light emitted to be considered. Red and white light can be specified, but the standard highlights that red LEDs can result in a loss of 80% of the light output.
ADT offers a range of conventional visual-alarm devices that can be installed as part of an EN54-23 visual-alarm system — including wall and ceiling category devices. ADT can also provide specifiers with guidance and support to ensure fire-detection and alarm system are compliant.
