Esprit features a wide range of control panels with 4, 6 or 12 on-board zone input terminals and can support up to 2 keypad zones. All control panels offer the ATZ zone doubling feature that enables you to connect two reporting devices to one input terminal. Each detection device occupies its own zone and communicates its status to the control panel. Depending on the control panel, the system can consist of up to 24 programmable zones that can be assigned to one or both partitions or can be assigned to neither partition to form a common area. The Esprit series offers you reliable, low-cost security that meets a host of customer needs.
