The MSS products in this section represent the first of many MAGNASPHERE technology contacts for non-high security applications. They are direct replacements for standard reed contacts, but have the security benefits of being UL634 listed as balanced magnetic switches (BMS) at prices competitive with good quality reed contacts.
Responding to a request from the State Department, MAGNASPHERE has introduced both a 1” concealed and a surface mount version of two and three switch contacts for non-high security installations. Each style offers both closed loop and open loop contact options and are made with Magnasphere BMS switch technology.
In response to those in the market that favor the lowest cost over the best security approach, MAGNASPHERE has introduced the L1.5, UL 634 Level 1 (9th edition) listed device. Although not as secure as the Level 2 HSS, it is has many of the same features and is superior to the many “grandfathered” reed switch based Level 1 contacts – hence the designation L1.5.
The acclaimed MAGNASPHERE HSS® devices are listed to UL634 Level 2 High Security Standard. In addition to their vastly increased security they offer many labor saving installation features, including embedded EOL resistors. Wiring schematics for all HSS versions are included in this section.
