SCEC Endorsed Products ASSA ABLOY has a wide range of SCEC endorsed products available under the ABLOY and Lockwood brands. These are categorised by the SEEPL security threat levels described below. The Security Construction and Equipment Committee (SCEC) is a standing interdepartmental committee responsible for the evaluation and endorsement of security equipment for use by Australian Commonwealth departments and agencies. ASIO's T4 Protective Security directorate, on behalf of SCEC, evaluates protective security products to determine their suitability for use in Australian Government facilities. Approved products are listed in the Security Equipment Evaluated Products List (SEEPL). SEEPL categorises products into four levels that indicate the relative ‘security strength’ of the item for use in Government applications. SL4 products offer a high level of security while SL1 products offer the lowest acceptable level of security for Government use.
