## Summary description

Satel S-4 is a white door/window magnetic contact sensor for intrusion detection. Compact dimensions (58.5 × 33 × 16.5 mm) suit mounting on frames and sashes. Designed to detect opening/closing events via a reed contact, it integrates with alarm and security systems to monitor access points in homes, offices and commercial premises.

## Long description

SATEL S-4 is a compact white door/window magnetic contact sensor designed for intrusion detection and perimeter protection. With dimensions of 58.5×33×16.5 mm, the S-4 consists of two stylish enclosures: a reed (magnetic) switch sensor and a magnet. When the two parts move apart, the reed contact opens and the detector signals an opening event. The device is suitable for surface mounting on door and window frames and includes a tamper contact and an additional terminal for easy connection of an end-of-line (EOL) resistor. The S-4 is compatible with alarm control panels that have normally closed (NC) inputs and can also be used as a control element in automation systems. It meets EN 50131-1 and EN 50131-2-6 standards for Grade 2.
Advantages
The SATEL S-4 combines compact size and simple installation, allowing discreet mounting on frames and sashes without occupying much space. Its reed switch operation provides reliable detection of opening/closing events while the built-in tamper contact increases security by reporting unauthorized removal. The additional terminal for an EOL resistor facilitates wiring and integration with standard alarm panels. Compliance with EN 50131 standards ensures the detector is suitable for Grade 2 security applications.
Suitable for
 Monitoring doors and windows in residential properties
 Securing access points in offices and commercial premises
 Integration with alarm control panels having NC inputs
 Use as a control element in building automation systems
Key specifications
 Type: Magnetic reed contact (magnetic sensor and magnet)
 Colour: White
 Mounting: Surface-mounted on frames or sashes (screw fastening)
 Dimensions: 58.5 × 33 × 16.5 mm
 Contacts: Normally closed (NC) input compatibility
 Additional features: Tamper contact; terminal for end-of-line (EOL) resistor
 Security standard: Complies with EN 50131-1 and EN 50131-2-6 (Grade 2)
How to use
Mount the two parts of the SATEL S-4 on the fixed frame and the moving sash or door so that the magnet aligns with the reed switch when closed. Secure the housings with screws provided or appropriate fasteners for the mounting surface. Connect the detector to the alarm control panel using the normally closed (NC) input wiring; if required by the installation, fit an end-of-line resistor to the dedicated terminal. Ensure the tamper contact is connected to the panel tamper input if remote monitoring of enclosure removal is needed. After wiring and mounting, test the sensor by opening and closing the door or window to confirm correct signalling to the control panel.
Usage recommendations
Install the detector on clean, dry surfaces and avoid mounting on metallic frames that could affect magnetic operation unless appropriate spacing or insulating materials are used. Position the magnet and sensor to maintain correct alignment and gap according to the mount surface; perform final checks with the alarm panel to verify correct NC signalling and tamper function. For optimal performance in exterior-exposed installations, select sheltered mounting locations or additional protective measures against moisture and extreme temperatures.
