Metal Web
The metal web is a new joist type used in the UK that combines the lightness of timber with the strength of the Posi Strut steel web, enabling it to span far greater distances, across a wide range of applications, at Ansell Lighting we partnered with Mitek for the ‘Metal Web’ ‘posi strut’ again this is based on the position and reach they currently have in the market. It is not used in 90 minute construction applications. Specifications for the relevant fire resistance rating categories are:

Faster, safer, building evacuations with Advanced Dynamic Safety Signage
F
ire and life safety systems manufacturer, Advanced, has extended its emergency lighting range with Dynamic Safety Signage (DSS) – proven to make building evacuations faster and safer.
In emergency situations, lack of information and confusion mean people often make poor decisions. DSS uses green moving and pulsing LED arrows to clearly indicate safe exits and red LED crosses to boldly show no-go areas. This distinctive indication supports effective escape and avoids congestion at exits.
DSS is ideal for settings where large numbers of people may be unfamiliar with emergency escape routes, e.g. university campuses, hospitals, stadiums and transport hubs. The new range of signage provides different tiers of functionality making it very versatile in meeting requirements across a wide range of sites and scenarios.
The lighting can be used standalone or integrated with conventional/addressable fire alarm panels

to trigger emergency lighting if an incident occurs. Cause and effect can be programmed, allowing DSS to be used adaptively. This ensures that as evacuation situations evolve, only the safest escape routes are highlighted whilst unviable exits are clearly marked as no-go areas. For added safety, DSS is also compatible with Advanced’s LuxIntelligent emergency lighting test system, making it easy to prove compliance and identify any parts of the system requiring attention. A study, conducted by the University of Greenwich, revealed that during a simulated emergency in an unfamiliar built environment, only 38% of people noticed conventional static emergency signage. When it was replaced with dynamic signage, 77% of people noticed it and 100% of the test group went on to follow the safe exit route.
Dynamic safety signage hardware consists of recessed, IP65 wall-mounted and wall/ceiling- mounted escape signs that are easy to install, can be retrofitted onto existing systems and provide a fully auto-tested system when used with LuxIntelligent,

ensuring compliance with BS5266-1. DSS can be triggered manually via a key switch, or automatically by integrating with any existing fire system using simple input/output modules.
Advanced offers a complete range of emergency lighting solutions, including LuxIntelligent, the automatic, addressable, emergency lighting test system, that shows all emergency lights are compliant and functioning, with no engineer involvement required. Each panel can automatically test and monitor nearly 1,000 luminaires and is easily networked using existing wiring and lights, keeping installation costs to a minimum.

“Plasterboard ceilings naturally act as a fire barrier but when a hole is cut into the ceiling to install a recessed downlight, its effectiveness is compromised and a potential fire hazard is created.”

Given the different regulations outlined above, selecting the right FRD can seem complicated which is why we have become the first manufacturer to introduce a range of FRD’s that comply with every category of joist type and every fire resistance rating, simplifying the specification process.
Ensuring compliance
Conveniently for electrical wholesalers, it is the responsibility of lighting manufacturers to provide evidence that a FRD is fully compliant. FRDs should come with full documentation of relevant testing, including test house certification
numbers, to provide absolute confidence that the downlight will offer maximum protection to the people inside a building, and the structure itself, in the event of a fire. Wholesalers should establish proof of certification with manufacturers before orders are placed.
