Today, we went to replace 41 old halogen fittings for some LED versions that only take 10% of the energy that the old ones did and created tons of heat. They were all wired to the mains with a naked connector block and the earths had been cut off. Disgusting quality of workmanship, but on a couple of them, the blocks, that should've been in an enclosure at least, had melted onto the fitting behind. If not for any other reason, this was a good one to replace the units, before the destruction would've inevitably happened. DO NOT get trades in based on their family and friends recommendations or by price. This is what you end up with. Look for reviews. Ours are on trustpilot. Choose wisely. https://lnkd.in/eUWTiva3 fuseservices.co.uk

Air barrier continuity Not on this one, we have the apartment pressurized to 50 pascals and it’s pouring out through the gaps in the “continuous” air barrier. Someone inspected and signed this one off, “I saw some air barrier” is about all you get. Look at how it’s being applied, remember 90% of the time it’s also the water control layer so make sure it’s shingled as it goes from bottom up or use manufacturers detailing when it’s not.

Checking Safe Escape From Multi Storey Buildings 1) Measure time for equipment to activate from fire signal. 2) Take pressure door readings over all floors with doors closed. 3) Check escape door opening forces with doors closed. 4) Calculate door velocity by activating smoke detector on each individual floor. 5) Check for door slamming and over pressure when doors start to close. 6) Using force gauge on door time how quickly the pressure dissipates to enable door opening. 7) Replicate an escape pattern for the escape door, check opening/closing reaction times and velocity. 8) Check all the above with ground floor open/closed

Our air transfer grilles combine air movement with fire protection – making buildings safer & more comfortable for occupants to live in. It is essential to select an intumescent or fire rated grille that is appropriate to the required application. For cold smoke protection, it is vital to add the Talkback Damper system - a fire and smoke resistant air transfer grille with a control shutter. Our ATG product selector ensures you quickly and easily find the right solution for your specific needs. 📏 Correct Specifications: Each result provides detailed information, including product specifications, relevant test standards, maximum sizes, installation instructions, and test evidence. 🌬️ Free Area Characteristics: Access extensive documentation on free area characteristics, detailing unobstructed areas for air flow. 🔍 Intuitive Search: Easily find tested solutions with comprehensive filters based on fire rating, building element, level of protection, product, or ID. 🔗 Try out our ATG Product Selector tool here: here Check out our Guide on Selecting the Right Air Transfer Grille here: https://lnkd.in/evHBvtxN #Specifiers #FireSafety #BuildingSafety

When designing staircase pressurisation, if using BS5588, we first need to classify the building use in accordance to use and whether there is fire fighting lobby. This is not required in MS1472. We next need to determine the stack effect, and calculate the additional cfm to counter stack effect. Then from building classification, we obtain the design pressure across the required doors and the velocity of air across the allowed open doors. We design to maximum of these two. So, if we do not do due diligence in our calculating stack effect, the calculated cfm to create door pressure will not be accurate. Click to register and learn smoke control via pressurisation which brings us back to the good old bernoulli's theorem. https://lnkd.in/gBMy2SUU

📝 Specifying high speed doors? This week Blake runs us through the 3 most important considerations for choosing the right high speed door👇 ✅ Type of controlled environment ✅ Type of door usage ✅ Installation environment #highperformancedoorways

"During the initial stages of the system design, it is important to answer the following questions: who needs to be notified; what do they need to know; when do they need to know it; where will they be; and why do they need to know?" Setting up a fire alarm and emergency notification system is not a one-size-fits-all process. There are many questions to answer and scenarios to consider before choosing the right systems for a building. This blog post on the NFPA's site breaks down the different notification strategies in a clear and simple way. Check it out, then contact our team to learn how we can customize our signage and control panels to meet your customers' mass notification needs!

Let’s talk fire alarms! Did you know.... any areas which require detection and have a void over 800mm (height) require detection within the void? This is usually what's above your suspended ceiling. From the upper side of your tiles/boarded ceiling, to the highest point of the roof space above. Underneath the suspended ceiling is a remote fire alarm indicator (in the picture below flat, easily seen if activated) which will flash red if the detector in the void is set off, letting you know the detector above has been activated. At BCS Electrics we, design, maintain and install fire alarms for your commercial or industrial property. If you have any questions or would like to know more about safety systems, get in touch. #firesafety #safetysystems #firealarmengineers

Q: What is an installer looking for from a membrane? A: An installer of outer wall systems is always under time constraints due to a variety of reason, delay in supply of parts, other trades behind schedule, adverse weather conditions to name but a few. Therefore, it is important that when it comes to fitting the membrane it is completed in a timely manner with a minimum of problems.   From an installers perspective he requires a membrane that will not rip when being installed, is nail resistant to tear, does no crease when folded, will not fray when cut, is water resistant if still open to the elements after fitting, is available on time with no delays.   The Stamisol Safe One membrane meets all these criteria and more with its breathability, fire protection and high UV resistance. It is the preferred choice of competent installers.
