PONZI TOS 1 + 1 is composed of 2 wings: one is a mobile sliding wing which overlaps with the semifixed lateral one. The advantage of this solution compared to the TOS 1R version is the placement of the AS automatism inside the building. With some manual pressure on the wings, in any stroke position they are found, (as it happens for any other TOS device) the wings break down, freeing the passage. Panic devices are inserted into the pillar.
