Description Performance Acoustic tests have been conducted in accordance with the standards listed below: BS-EN 10140-1 BS-EN 10140-2 A minimum of 34 to 35dB can be achieved using standard FD30 and FD60 single and double leaf doorsets with and without vision panels. ACS-1 has been successfully tested to BS476 pt 31;1 for cold smoke sealing (air leakage). Cycling test: 100,000 opening and closing cycles. Fitting ACS-1 should be surface fixed at the junction of the door stop and frame at the point the doorleaf closes into the stop. Remove the backing paper from one side only and carefully position applying light pressure to locate the seal, carry out the same with the second leg and once satisfied that it is correctly positioned apply further pressure to both legs.
