Command Equipment

Command
Command controls are the items that give systems a signal to operate. There are currently about a dozen ways of giving command, most of which are listed within the “Products” section of this web site. Usually systems have more than one means of command, with radio controls the most popular. The successful performance and life expectancy of a command item is subject to its ; Environmental suitability, Location and User friendliness.

Safety devices
Safety devices are the items that stop the system from closing while they detect an obstruction. There are about half a dozen ways of providing system safety, most of which are listed within the “Products” section of this web site. Very few systems use safety devices for stopping the system from opening, but it is possible. The main objective of good safety cover for any system is to prevent impact from occurring. .It is the moving vehicle that causes most damage, not the moving gate or barrier and most accidents happen because the vehicle is driven into a closing system. Therefore devices should be chosen and located to give the best Safety cover for each individual site. The most common safety item is a pair of photoswitches S1 used in most domestic installations. However, as the detection area is a thin beam, larger coverage devices are better such as induction loops S2. A combination of safety devices is good practise however it inevitably becomes more of an investment. All systems should have adequate safety cover and the higher the usage of the system the more likely the chance of accidents.

Miscellaneous
Miscellaneous items are the other essential components of a system that make it complete. Over a dozen items are shown within the “Products” section of this web site and include Enclosures, Locks, Communications, CCTV, Letterboxes, Lighting etc. These items are often over looked and do not seem important until the installation is all but finished. If consideration is not given early enough the cost of including such items can be far greater than it need be. It is good practise to allow for the addition of controls and equipment by installing the right ducting and spare cores within each cable run.
