Spider Door Contact

Black Finish
2-Wire “Form B” Output: Common+Normally Closed

(COMING SOON)

Nearly all Security Door Contact Sensors utilize reed switches. Invented back in 1936 by Bell Laboratories for telephones… Overwhelmingly adopted by the security alarm industry ever since.

Problem is— they can be bypassed in seconds.

In any security discipline: A security layer this insubstantial is unacceptable! So after 2 years of meticulous engineering, and in persevering through over 160+ iterations, we’ve successfully created a new revolutionary design!

Security Built Right. Unlike with reed switches, our Spider Door Contact CANNOT BE SHUNTED with a bypass magnet.*

What’s In Our Tech? Our design consists of ‘Dual-Repelling’ Magnets: (1) in the sensor on the door frame & (1) on the door’s topside. When the door is closed, the 2 magnets will align & synchronize… resting at a floating balance. When a door is opened this balance will be toppled, triggering an alarm.

Key Anti-Tampering Feature: With the door closed, irregular magnetism sensed will also induce imbalance & would also create an instant alarm.**

A Unique Twist~ Our innovative door magnet design introduces a vertical adjustment feature that also helps to prevent false alarms! Raise or lower door magnets back to ideal gappings with the simple turn of a screwdriver!
