## Long description

The Olympia TF 400 White door/window sensor pack contains four compact magnetic sensors designed to detect opening and closing of doors and windows. Each sensor delivers a loud 90 dB alarm to alert occupants immediately when a contact is broken. The compact white housing measures 40 mm wide, 20 mm deep and 60 mm high, making the units easy to place discreetly on frames. Powered by LR44 batteries, the sensors are intended for indoor use within an operating temperature range of 0 to 49 °C.
Advantages
These sensors offer a high-decibel audible alert for fast detection of unauthorized entry, combined with compact dimensions that allow unobtrusive mounting on most doors and window frames. The use of standard LR44 batteries simplifies replacement and maintenance. The pack of four sensors enables coverage of multiple entry points in a home or small office without additional purchases.
Suitable for
Monitoring main and secondary doors in apartments or houses
Securing windows on ground floors and accessible rooms
Protecting interior doors leading to storage or server rooms
Short-term or temporary installations in rental properties or offices
