Potter Electric Signal 2020420 High Security Double Contact

Product Description

The Potter Electric Signal Co. US 2020420 is a high security double contact designed for specialized alarm and detection system applications. This contact provides a dual-circuit switching configuration that delivers increased tamper resistance and redundancy compared to standard single-contact devices. It is installed by licensed fire alarm technicians, security system integrators, and low-voltage electricians working on commercial or industrial protection systems where enhanced contact reliability is required.

The 2020420 high security double contact is suited for special application installations where a single contact point is insufficient for system requirements. Typical deployments include commercial fire alarm panels, access control perimeter monitoring, and security detection loops that demand verified switching confirmation. It is sold as an individual unit and is appropriate for new installations as well as retrofit or upgrade projects on existing monitored systems.

Key Features

• Double contact design provides redundant switching for increased reliability and tamper detection
• Classified under special application contacts for use in demanding alarm and security installations
• Single-unit packaging supports precise quantity ordering for service calls and panel builds
• Compatible with low-voltage alarm and detection circuit architectures

Compatibility

Designed as a special application contact for use in commercial fire alarm, security, and detection systems requiring high security double contact switching. Refer to system documentation and the manufacturer datasheet for verified panel and loop compatibility before installation.

Installation Notes

Installation should be performed by a licensed fire alarm technician or low-voltage electrician in accordance with NFPA 72 and applicable local codes. De-energize and place the alarm panel in test mode before disconnecting or connecting any contact wiring. Verify all circuit polarities and conductor terminations are secure before restoring power and returning the system to normal operation. Do not bypass or jumper the contact during testing without following the authority having jurisdiction procedures.
