## Summary description

SATEL K-1 2E is a wired door/window sensor in white designed for perimeter protection of doors and windows. It operates with a 20 V power supply input and weighs 10 g. The device provides magnetic contact sensing for intrusion detection and is suitable for integration into wired alarm and security systems in residential or commercial installations.

## Long description

SATEL K-1 2E is a wired magnetic door and window sensor in white designed for perimeter protection of doors, windows and similar openings. The sensor comprises two watertight parts — a reed switch housing and a magnet — that are surface-mounted with screws to frames. When the two parts separate, the reed switch circuit opens and the connected alarm system registers a violation. The unit is intended for integration into wired alarm and security systems for residential and commercial installations and requires a 20 V power input.
Advantages
The SATEL K-1 2E provides reliable magnetic contact sensing in a compact, low-weight (10 g) enclosure suitable for discreet installation. Its two-part watertight construction reduces the risk of environmental interference, while the surface-mount design allows installation on standard door and window frames without the need for recessed mounting. Being a wired device, it offers stable communication with alarm control panels and avoids issues associated with battery replacement or wireless signal interference.
Suitable for
 Perimeter protection of doors in homes and offices
 Window protection in residential and commercial buildings
 Integration into wired alarm and security control panels
 Locations where a low-profile, surface-mounted magnetic contact is required
Key specifications
 Type: Wired magnetic contact sensor (reed switch)
 Colour: White
 Power input: 20 V
 Weight: 10 g
 Mounting: Surface mounting with screws
 Construction: Two-part, watertight (sensor housing + magnet)
How to use
Install the reed switch housing on the fixed frame (door or window frame) and the magnet on the moving part (door leaf or window sash) so that the two parts align when closed. Fasten both parts securely with screws using the provided mounting holes or designated mounting points. Connect the sensor wires to the alarm system input following the control panel documentation and ensure a stable 20 V supply where required. Test the contact by opening and closing the protected element to confirm the alarm system registers the circuit change.
Usage recommendations
Position the sensor and magnet with minimal gap and correct alignment to ensure reliable detection; avoid placing the magnet near large metal objects that may affect the magnetic field. For outdoor or high-humidity environments, verify the watertight seals after installation. Periodically test the contact as part of routine system maintenance to ensure continued operation.
