The 2700 series high security magnetic contacts with triple-biased reeds are highly resistant to defeat by external magnets. For added security, magnetic field tamper and pry tamper are standard features. Each 2700 contact and actuation magnet set is configured at the factory for the effects of steel.

The 2700 series contacts can be used to protect doors in high-security locations or where high-value materials are stored. All the contacts in this series have been listed by the U.S. Department of Defense in DIAM 50-3 for use at secure compartmented information facilities (SCIFs).
