The GR2707 series high security switches are built with three C form reeds making them resistant to magnetic tamper and defeat. For added security, magnetic field tamper and pry tamper are standard features. Each GR2707 contact and actuation magnet set is factory compensated for the effects of steel.

The GR2707 Series can be used to protect doors in high security locations; airports, biotechnology labs and other medical research settings, warehouses, manufacturing plants, jewelry stores, banks, data processing centers, military bases, ammunition depots and energy-generation facilities.

The GR2707-A is configured in a SPDT configuration using three C form reeds. The GR2707-AD contains six C form reeds wired in a DPDT configuration. A supervisory loop with magnetic tamper feature is included in both models. A pry tamper connection for the 24 hour loop is included with both models.
