Magnasphere Corp HSS-L2D-002 Special Application Contact

Product Description

The MAGNASPHERE CORP HSS-L2D-002 is a special application contact designed for use in security and alarm system wiring configurations. This component supports a 1K series parallel embedded end-of-line (EOL) resistor circuit topology, which is a standard method used in supervised alarm loops to allow a control panel to distinguish between a normal, open, or shorted zone condition. It is typically installed by security system technicians and low-voltage electricians working on intrusion detection or access control systems.

This contact is suited for supervised zone wiring in residential and commercial alarm installations where an embedded EOL resistor configuration is required. The series parallel wiring method allows the alarm panel to monitor zone integrity continuously, making it a reliable choice for code-compliant supervised circuits in new installations and retrofit projects alike.

Key Features

• 1K series parallel embedded EOL resistor configuration for supervised alarm zone wiring
• Embedded EOL design eliminates the need for a separate external resistor component
• Suitable for use in intrusion detection and access control panel zone inputs
• Sold individually as a single unit per package

Compatibility

Designed as an OEM-style replacement or new-installation contact for special application supervised alarm zone circuits requiring a 1K series parallel embedded end-of-line resistor topology.

Installation Notes

Installation should be performed by a licensed low-voltage technician or security system installer in accordance with applicable local and national codes, including NFPA 72 where applicable. Power down or disarm the alarm control panel zone before servicing or replacing contacts to avoid false alarms or panel faults. Follow the control panel manufacturer wiring diagram for the correct series parallel EOL placement within the zone loop.
