## Summary description

Wired door/window magnetic contact sensor SATEL S-1 in white. Designed for intrusion detection in alarm and access-control systems, it uses a wired connection and requires a 20 V power supply input. Compact and lightweight (29 g), the sensor detects opening/closing of doors or windows and is suitable for residential and commercial installations.

## Long description

Wired door/window magnetic contact sensor SATEL S-1 in white is a compact perimeter protection device for alarm and access-control systems. The sensor comprises two sealed parts — a reed switch unit and a magnet — mounted on the door or window frame. When the parts separate, the sensor circuit opens and the alarm control panel registers an intrusion. The S-1 is surface-mounted with screws, includes a tamper loop for cover protection, and is compatible with control panels that provide NC-type inputs. The device is lightweight and designed for residential and commercial installations that require Grade 2 compliance.
Advantages
The SATEL S-1 offers a compact, low-profile design that simplifies installation on door and window frames. Its sealed construction provides reliable operation in typical indoor conditions while reducing the risk of dust or moisture-related faults. The wired connection ensures a stable signal path to alarm control panels and automation systems. Built to meet EN 50131-1 and EN 50131-2-6 requirements for Grade 2, the sensor includes a tamper loop to detect unauthorized opening of the unit.
Suitable for
Intrusion detection on doors and windows in homes and apartments
Perimeter monitoring in small commercial spaces and offices
Integration with alarm control panels requiring NC inputs
Basic automation tasks that use magnetic contact status as a control signal

How to use
Mount the reed switch part to the fixed frame and the magnet part to the moving element (door or window) so that the two parts align when closed. Secure both parts with screws provided or appropriate fasteners for the mounting surface. Connect the wired contacts to the alarm control panel NC inputs following the panel manufacturer’s wiring diagram and ensure the tamper loop is connected to the designated tamper input. After wiring, test the sensor by opening and closing the door or window to verify the control panel registers open and closed states correctly.
Usage recommendations
Place the sensor where the magnet and reed switch can align with minimal gap when closed; avoid mounting locations exposed to direct rain or extreme moisture. Use the tamper loop to monitor the device housing and include the sensor in routine system tests. For reliable operation, follow the alarm control panel manufacturer’s wiring and input voltage guidelines and perform periodic inspections to confirm secure mounting and intact wiring.
