Ajax Superior DoorProtect G3 Jeweller

Superior DoorProtect G3 gives you reliable Grade 3 door protection with dual reed switches, an accelerometer, and a magnetometer working together to catch any attempt to open, shift, or tamper with a door. It is built for sites where you need a higher level of intrusion detection without adding complexity to the install.

The detector watches for opening, shock, tilt, and magnetic interference, giving you layered protection on doors that are at risk of forced entry or subtle manipulation. You can tune shock, tilt, and magnetometer sensitivity in the app, so you keep false alarms low while still meeting strict security requirements.

The device talks to the hub over Superior Jeweller or Wings, depending on the hub or range extender. On open sites you can reach up to 3,500 metres. Firmware updates are handled over the air, so you can keep the system current without returning to site.

A connector is built in for a third party detector, allowing you to bring a wired NC contact into the Ajax system when needed. That helps when you are upgrading an existing site and want to reuse a built in contact on a door or shutter.

The unit runs on a CR123A battery, with up to five years of life depending on settings. It comes in black or white, and sits in an IP30 housing at 103 by 22 by 21 millimetres.
