The unit is actuated by self-closing buttons on the front, with a required pressure of less than 2 kg. The buttons open the internal valves with a flow regulator and adjustable adjustment.

The vandal-resistant spouts are made of polished stainless steel (the spout can be fired with a laboratory test torch) and provide a stable water flow over a pressure range of 1.4 to 7.2 bar. The unit complies with the following US regulations: standard ANSI A117.1, Act 111-380 (on lead elimination), CHSC 116875 and NSF/ANSI 61, section 9. The design complies with the ADA Disability Access Act, as far as standing and children are concerned, provided it is properly installed. The unit should be mounted on a stable surface that provides good drainage (recommended concrete slab). It has an inspection door allowing access to the internal components of the sprinkler. Assembly anchors included. It is approved by the PZH (Polish National Institute of Hygiene) and bears the B safety mark for construction products (ITB - Institute of Building Technology).
