Product Highlights
- Biased for high security: begins as a single pole double throw reed switch biased into an opposite condition — creating a double-tripping switch that can only be actuated inside a specific window of operation defined by a maximum and minimum actuation distance
- Configuration 4B: enhanced biased configuration providing a tighter actuation window and greater resistance to defeat by a secondary magnet compared to Configuration 1B — the higher the configuration number, generally the more difficult the magnet defeat attempt
- At approximately the center of the actuation window, should a compromising magnet be applied, it would be similar to moving the actuation magnet to the inside release limit, causing the switch to release and generate an alarm

GRI 11253-B-ZD + Key Benefits
- High Security Design: Biased for high security, the switch operates through a double-tripping mechanism, ensuring it can only be activated within a defined distance, significantly reducing false alarms.
- Configuration 4B Advantages: This enhanced setting provides a tighter actuation window and increased resistance to external magnetic defeat attempts, making it more reliable than lower configuration options.
- Alarm Triggering Mechanism: If a compromising magnet is applied near the center of the actuation window, the switch will release, generating an alarm, thus adding an extra layer of security.
