## Summary description

SATEL S-2 is a wired door/window sensor designed for intrusion detection in alarm and security systems. The white sensor uses wired connectivity and requires a 20 V power supply input. It detects opening/closing of doors or windows and is suitable for residential and commercial installations where permanent wired connections are preferred.

## Long description

The SATEL S-2 is a wired magnetic contact detector for flush mounting, designed to secure doors, windows and other openings by generating an alarm when they are opened. The device comprises two watertight parts: a reed (magnetic) sensor and a magnet. Faces of both parts must be aligned and in contact; separating them opens the sensor circuit and registers a violation. The detector includes a tamper loop and is suitable for integration with alarm control panels that provide normally closed (NC) inputs or for use as a control element in automation systems. It is compliant with EN 50131-1 and EN 50131-2-6 standards for Grade 2.
Advantages
The S-2 is made for flush mounting into prepared holes in wooden or plastic frames, providing a discreet, low-profile installation. Its two-part watertight construction protects internal components, while the tamper loop offers added protection against unauthorized removal. Wired connectivity ensures a stable signal to alarm control panels that accept NC inputs. Conformance to relevant EN standards confirms suitability for Grade 2 perimeter protection.

After installation, test the detector operation by opening and closing the protected opening and checking the panel registers the change of state.
Usage recommendations
Install the S-2 in locations where recessed mounting is possible and where the white color and compact profile provide a discreet appearance; verify compatibility with the alarm panel’s NC inputs and perform regular tests and tamper checks as part of routine maintenance.
