Many manufacturers and distributor’s print a value in their literature with a holding force of “x” without providing any certified test evidence. The simplified test, which many in the industry carry out, consists of a direct pull test on a test table; however this method has been shown not to accurately represent how the product would react in the normal working conditions. To correct this anomaly the method of testing under TS010:2016 addresses this issue by ensuring that the holding force registered is as near to true value of that which would be recorded when the product is installed onto a door and frame.
The Securefast electro-magnetic lock range comprises face to face, mortice and transom housed locks in both monitored and unmonitored options. Securefast electro-magnets have been approved and certified to TS010:2016, in addition to providing supporting fire test evidence for 30 and 60 minute fire doors.
Market research carried out by Securefast indicates that the increasing popularity of electronic access control systems is contributing to the market growth of electro-magnetic locking devices and electric releases, each of which are forecasted to outperform the growth of mechanical locks over the coming years. Access Control systems are becoming increasingly popular because they provide a higher level of security and control of personnel, while offering integrated opportunities with time management and building automation systems.
More electro-magnetic locks are being used on Security, Escape and Fire Doors with little or no valid test evidence regarding performance, fire, environmental or security holding force. Electro-magnetic locks are now being used as part of security tests such as PAS24:2012 (Enhanced Security Performance Requirements for Doorsets and Windows in the UK) and plans in the future are to use them when testing to EN 13637(Electrically Controlled Exit Systems).
The new DHF Technical Standard TS010:2016 for electro-magnetic locking devices is a performance requirement standard that will give specifiers and manufacturers of doorsets the confidence that the electro-magnetic locking device will perform to the required standard and covers face to face fixed, mortice, shear and external electro-magnetic devices.
TS010 will give the door manufacturer / distributor the confidence of consistency in electro-magnetic lock performance. The eight digit classification code includes the 6th digit for the holding force, which falls in line with the security classification used by BSIA specifiers guide to Access Control Systems, the European Standard EN 50133-1 and the classification used by NSI in their Code of Practice for Planning, Installation and Maintenance of Access Control Systems NCP109.
With many electro-magnetic locks used on fire doors, specifiers will be able to check from the 3rd digit of the classification code that the individual product has been tested or accessed for use on fire doors by a third party test house, which in the past has been ignored by many installers as no evidence was shown on the packaging, instructions or in manufacturer’s catalogues.
Within the Classification Code for TS010 specifiers can identify features of the product, such as the 4th digit shows if the product is supplied with safety straps and bolts whilst the 7th digit shows if the device is monitored either visually, for example with an LED Indicator or audio using a buzzer etc. allowing specifiers to know what they are specifying.
To assist customers to select the correct product, Securefast have produced a number of Declaration of Conformance which are available to download from their website which give relative information such details of fire test EN1634-1, performance test TS010:2016 and EMC test.
