by Brianna Crandall — August 14, 2015—Euralarm, the association of European manufacturers, installers and service providers of the electronic fire safety and security industry, has published an application guideline on primary visual alarm devices and supplementary indicating devices. This document provides information on the use and requirements of EN 54-23 compliant visual alarm devices (VADs) and also explains typical applications where a supplementary indicating device may be suitable.
Since January 2014, visual alarm devices (VADs) used for warning building occupants of a fire emergency must comply with the requirements of EN 54-23, and suppliers/manufacturers of such devices must fulfil the requirements of the CPR when placing such devices on the EU market.
The document stresses that sounder beacon devices that do not comply with these regulations can still be used, as long as they are only intended to be used as supplementary indication devices. The manufacturer or supplier should clearly state to which standard the device is tested and certified. A fire-risk assessment of a premise should indicate whether an EN 54-23 compliant VAD is required.
This norm became mandatory on the first of January 2014 and states that VADs are intended to signal a visual warning of fire to the occupants of a building in order that such persons can take appropriate measures such as evacuate the building. EN 54-23 does not apply to supplementary indication devices, although this does not imply that such devices are not permitted, clarifies Euralarm.
In order to establish a distinction between visual alarm devices (VADs) that comply with EN 54-23 and those that are used to warn occupants of a fire, Euralarm recommends that devices intended for supplementary indication that are not compliant with EN 54-23 should be referred to as visual indicating devices, or VIDs.
The document also focuses attention on the mounting requirements and illumination coverage volume when selecting a VAD. They are divided into three categories: C, W, and O. The application requirements for category O are not well defined in EN 54-23 because they rely purely on the application and installation data supplied by the manufacturers, so the guidance advises what information should be provided by the manufacturer or supplier to allow correct application of the device.
Lastly, Euralarm gives several examples from the United Kingdom and France on the use of VADs and VIDs.
