Eaton i-on Compact Audible Kit includes 20 zone wireless control panel, three dual technology passive infra-red (PIR) motion detectors, slimline magnetic door/window contact, external siren, two-way key fob. 20 Zone wireless control panel, the wireless intruder panel with built-in keypad offers up to 20 radio zones and offers reduced time, cost and complexity of installation, programming and maintenance- only requiring connection to one cable (mains) to get the system up and running. The XCELR series of dual technology PIR’s has a specially designed spherical lens that generates a five-layered beam which when combined with a dual element sensor deliver superior detection precision. Radio door or window contacts consist of two components: the sensor (normally mounted on the door or window frame) and the magnet. When the door or window opens, the two devices separate, which triggers the sensor. External sirens (or sounders) act as frontline deterrents against the threat of intrusion whether located on a semi-detached house or large warehouse. The key fob allows for the simple set and unset of the system. The fob can also provide feedback on system status, provide confirmation that the system has been set upon exit and is third-party certified by INCERT.
