Kidde Edwards 2757-L High Security Triple Bias Contact

Product Description

The KIDDE EDWARDS 2757-L is a high-security ANSI triple bias contact designed for special application door and window monitoring in commercial and industrial security systems. Triple bias technology uses multiple internal magnets to create a more tamper-resistant switching circuit than standard single- or double-bias contacts, making it significantly harder to defeat with an external magnet. This contact is specified by security integrators and life-safety technicians where high-security perimeter protection is required by code or by the authority having jurisdiction.

The 2757-L is suited for commercial facilities, government installations, correctional environments, and other high-security applications where standard contacts do not meet the required threat level. It is installed at access-controlled door and window openings as part of a broader intrusion detection or access control system. The ANSI form factor ensures dimensional compatibility with industry-standard hardware cutouts and mounting plates used in commercial door frames.

Key Features

• Triple bias design resists magnetic defeat attempts on secured perimeter openings
• ANSI form factor fits standard commercial door and window hardware cutouts
• Rated for special application use where enhanced tamper resistance is required
• Single unit packaging suitable for individual door or opening installation

Compatibility

Designed as an OEM-style replacement or new-installation contact for special application security and access control systems requiring ANSI-format high-security magnetic contacts.

Installation Notes

Installation should be performed by a licensed security systems technician or alarm installer in accordance with local codes and the authority having jurisdiction. De-energize the associated control panel zone before wiring the contact to prevent false alarms or damage to the panel. Consult the manufacturer product manual for terminal assignments, gap tolerances, and mounting orientation before final installation. Do not substitute standard-bias contacts in applications where the triple bias configuration is specified for security compliance.
