To meet growing demand for visual alarm devices (VADs) and ensure compliance with European EN 54-23 manufacturing standards, Eaton’s Fulleon Business has developed the LX range of fully certified beacons.The range comprises of a wall category and ceiling category beacon, a low current sounder beacon, a low current IP66 sounder beacon and a RoLP (Roshni) sounder beacon, which is fully compatible with all existing RoLP Sounders.
The most recent addition to the range is the highly efficient Squashni Base LX ceiling device. The Squashni Base LX delivers a coverage volume radius of 15 metres and a square area of 10.6 metres, in line with the spacing specifications for both smoke and heat detectors. The device’s universal fitting means almost all detectors can be incorporated directly into the unit. This reduces the number of products that would ordinarily be needed in a large public space, as there is no need for separate installation points for detection and notification products. Further economies are achieved by the low current consumption of the unit.
Maximum Coverage, Minimum Consumption
The LX range was developed to provide the lowest possible current consumption while still giving the highest possible light output, so as to maximise the number of devices on a circuit.
The LX range centres on patented lens technology that manages the distribution of light with extraordinary efficiency. Any light distributed outside of the necessary volume prescribed in EN 54-23 is a waste of power; the LX lens refracts light to remove hot spots (concentrated areas of light intensity) directly in front of the LED before re-distributing the light to illuminate dark spots. This method delivers the intensity of light required whilst minimising current consumption.
EN 54-23 Compliant Red Flash
EN 54-23 allows for either a red or a white flash. In many parts of Europe a red flash is synonymous with fire. To develop a red flash option that achieves the required 0.4 lux specified by EN 54-23, without compromising the current consumption, is extremely challenging. With the LX range, this has been achieved; LX products are available in either a red or white flash with no compromise on current consumption.
Help with Specifying & Product Selection
The FIA and LPCB have produced a Code of Practice, CoP0001, to help system designers specify the placement of visual alarm devices. In the recent update to BS5839-1 2013, CoP0001 is referenced, where the use of alarm beacons is chosen as a solution to a risk assessment.
Eaton’s Fulleon business aims to make the transition to meet the new requirements as simple as possible. An online specification tool for the LX range has been developed, which will identify how many devices are required and their combined current consumption for a given area. The tool allows the user to quickly assess the impact of changing the flash rate and the type of product selected.
A 20-page pocket guide, ‘Introduction to EN 54-23’, has been created to help with the planning, installation, commissioning and maintenance of VADs. Further resources, including offline design tools and product certificates are also available.
