## Long description

Satell S-4 DG magnetic door/window contact is a compact sensor intended for intrusion detection in alarm systems. The device features a magnetic reed contact that provides normally closed or normally open signaling and an integrated tamper switch that detects removal or opening of the housing. Finished in dark gray, the S-4 DG is suitable for mounting on door and window frames where discreet, reliable monitoring of opening and closing events is required.
Advantages
The S-4 DG combines a magnetic contact and a built-in tamper switch in a single enclosure, reducing installation complexity and saving space. Its dark gray finish allows discreet placement on many types of frames and surfaces. The contact supports both NC and NO wiring configurations, enabling compatibility with a wide range of security control panels and alarm systems. Designed for standard mounting, the unit provides stable mechanical and electrical performance for everyday security applications.

Key specifications
Type: Magnetic reed contact with built-in tamper switch
Mounting: Surface mount on door or window frames
Signal configuration: Supports normally closed (NC) and normally open (NO) contacts
Housing color: Dark gray
Construction: Compact enclosure suitable for standard installation apertures
How to use
Install the magnetic contact and the magnet on corresponding positions of the door or window and its frame so that they align when the door/window is closed. Connect the wiring to the alarm control panel following the chosen NC or NO configuration and the panel manufacturer’s wiring diagram. Secure the housing to the surface with appropriate fasteners and verify that the tamper switch is functional and the contact changes state reliably when the door or window is opened and closed. Perform a system test to confirm correct signaling to the alarm control unit.
Usage recommendations
Position the sensor and magnet with minimal gap and avoid placing the unit near large ferromagnetic objects that could affect operation. Use appropriate screws or adhesive compatible with the mounting surface; when used outdoors or in humid environments, ensure additional protection against moisture. Test the tamper switch during routine maintenance to ensure the device reports unauthorized removal or housing opening.
