Description
Magnetic contact detectors belong to the essential devices of perimeter protection. They are used to protect doors, windows, etc., by triggering alarm when they are open. The S-4 detector is designed for surface mounting by fastening it with screws to window frame, door frame, etc. S-4 consists of two parts placed in stylish enclosures: the reed switch (magnetic) sensor and the magnet. Moving one part away from the other breaks the sensor circuit, which is indicated as a violation. The detector is provided with a tamper contact and an additional terminal M for easy installation of EOL resistor.
S-4 is designed to work with any alarm control panel having NC inputs as well as to be used in automation system as a control element. It meets the requirements of EN 50131-1 and EN 50131-2-6 standards for Grade 2.
The device is available in two color versions: white (S-4) and brown (S-4 BR).
- surface mounted
- tamper contact with terminals
