Stern’s Programmable Piezo kit for showers is specially designed to be used in high security environments. Stern’s anti-ligature, vandal resistant shower heads are ideal to be combined with Stern’s piezo kits. Stern’s piezo kit is fully programmable timed flow. Lock out times available upon request.
The robust design and the fact that the switch has no moving parts almost completely eliminate the need for maintenance. The piezo switches have a vandal resistant, anti ligature design with a „non hold open“ feature. If needed, remote maintenance is possible through a single wire that leads from the service area to each piezo button in the prison cell. Since piezo switches provide an accurate water flow, this technology plays an important role in helping to conserve water. The flow time is programmable and the provides extra water saving possibilities by giving the inmate the possibility to close the water flow even if the water cycle has not finished.
Each inmate’s cell has a piezo switches an interface to control flow at the shower. The piezo switch at the shower control is connected to a solenoid valve that opens and closes the water flow. Each activation gives a pre-set run cycle at a pre-determined temperature.
