US91-30EN Jumbo Publication Number: PB3022 DEC/11 Dewhurst US91-30EN Jumbo Pushbutton The US91-30EN Jumbo Pushbutton is a classic round extra large button. The button was designed not only to meet the requirements of EN81-70 Annex G.1., but also for use in larger buildings such as hospitals, airports and shopping centres, where the sheer scale of the building necessitates a larger button. The black background to the pressel provides a clear contrast to the tactile legend and also to the faceplate as required by EN81-70. On call acceptance the large 30mm high legend illuminates brightly and you have the choice of many colour options. The US91-30EN Jumbo has an identical appearance to the standard US91-EN and so the two buttons can be used on faceplates together when appropriate.
