Structural assessment should take account of wind load. The system should remain safe when subject to foreseeable wind loadings. A system is not necessarily required to remain functional in high winds (although client/contractual requirements might require otherwise); the system should, however, remain safe. We offer the following advice in terms of likely maximum wind gust speeds: 1) 50 mph = sheltered (inner-city, built-up areas with close buildings on all sides) 2) 70 mph = normal (normal urban environments) 3) 100 mph = exposed (open, rural, hilltop or coastal environments).

As electro-magnetic locks have no mechanical parts which can fail, then simply removing the power releases the door. These devices are available with different holding forces to suit the security requirements and, to support the use of fail unlocked devices, a battery backup in the power supply ensures that if power is cut, other than from a fire alarm, that the door remains secure.

DHF is often asked if sharp toppings as a climbing deterrent are acceptable on a powered gate. Clearly, sharp toppings on fences and walls are commonplace; palisade fencing has points at the top of each pale. However, can this be extended to gates that move under power? Read DHF's new publication 'Automated Gates & the use of Sharp Toppings' for further guidance: https://bit.ly/DHF-GenInfo #AutomatedGates #SharpToppings #ElectricGates #PoweredGates

DHF has recently released a new publication titled 'Interface between fire shutters, the fire detection & alarm systems' a Best Practice Guide to BS 7273-6. This publication addresses the major issues that should be considered when specifying, ordering or using the products it describes. It aims to provide the reader with a concise document which includes a summary of relevant sections from the technical product standard. The reader will then be in a position to seek further specialist advice where necessary and recognise GENUINE conformity to the standard.
