- Material & Care
The Protect-800 Wireless Gate/Door Left Open Alert Kit provides a silent but highly visible warning system to ensure gates, roller shutters, or doors are not accidentally left open. Featuring a powerful 12V security floodlight and long-range wireless technology, it’s ideal for safeguarding children, pets, and property.
Designed in response to customer requests, this system provides peace of mind by alerting you visually when gates or doors are left unsecured. Sirens, buzzers, or additional accessories can be added for audible alerts if required.
How It Works
-
A weatherproof transmitter box (IP65 rated) with dual battery-powered boards is fitted to your gate, roller shutter, or door.
-
The armoured contact switch detects if the gate/door is left open, sending a wireless signal to the outdoor receiver (up to 800m range, 400–600m in most real-life installs).
-
The receiver activates the 12V security floodlight while the gate/door remains open.
-
Using the long-range remote control (800m), you can arm/disarm the system or trigger the floodlight manually via the SOS function (latched ON until switched OFF).
-
Optional indoor chime receivers can be added for inside notifications (non-latching).
