The Honeywell Access S-4 is a surge supressor used with Honeywell's N-1000-II, N-1000-III, N-1000-IV, NS2 and NS2+ access control panels. The supressor protects the panel against electrical spikes caused by excess energy from collasping electrical fields that could potentially damage the device. The supressor is connected through a relay contact included on the panel.
