FSH FSS1-S Surface Mount High Security Reed Switch

Product SKU: FSS1-S

Product Overview

The FSH FSS1-S Surface Mount High Security Reed Switch is a professional door monitoring sensor designed for high-security environments where accurate door position detection is essential. Unlike traditional magnetic reed switches, the FSS1-S uses an advanced multi-sensor design to detect a unique magnetic footprint from a specially paired magnet array. This technology significantly improves tamper resistance and reliability, making the sensor suitable for secure facilities such as government buildings, critical infrastructure and high-risk commercial installations.

Why Choose the FSS1-S

The FSS1-S is designed for security applications where conventional door sensors may be vulnerable to tampering or bypass. Its advanced sensing technology analyses multiple magnetic characteristics including polarity, strength and position, ensuring the system recognises only the correct magnetic signature. This greatly reduces the risk of spoofing or magnetic interference. The sensor also includes built-in tamper detection and environmental protection, providing dependable monitoring in demanding security installations.

Key Capabilities

FAQs

1. How does a high security reed switch differ from a standard door sensor?
   Traditional reed switches typically use a single magnet and reed contact to detect door position. High security sensors like the FSS1-S use multiple magnetic sensors that analyse a unique magnetic pattern from a matched magnet array. This technology makes it far more difficult to bypass using external magnets and improves reliability in high-security installations.
2. What does SCEC Security Level 4 mean?
   Security Level 4 certification indicates the device meets strict security evaluation requirements for high-risk applications. Products approved to this level are designed to resist tampering and provide reliable monitoring for sensitive government or critical infrastructure environments.
3. Can this sensor integrate with alarm or access control systems?
   Yes. The FSS1-S provides alarm and tamper contacts that can connect directly to intrusion alarm panels or access control systems. This allows the system to monitor door position, detect forced opening and generate alerts if the sensor housing is tampered with.
