An easy to install, simple to operate four zone system with new two wire technology. All system components are connected to the control unit using two core non-polarity wires.

Simple operation, convenient push button Home and Out arming. Home and Out modes are pre-programmed for user convenience. When system switched Off, door chime function is available.

All sensors, sounders are 24hr line protected and fully supervised. Any attempt to interfere with the system, such as cutting the wires or opening any of the PIR detector, will trigger the alarm and be identified by flashing LED’s and zone indicator.

Tamper attacks to any zone sensor will trigger the alarm and be identified by flashing LED’s and zone indicator, but the rest of the system is protected.

Expandable system, two PIR’s can be fitted to one PIR zone, therefore the system can be expanded to have 4 PIR’s plus many contacts. Also there is the option of adding a telephone dialler with easy wiring connections.
