Magnasphere Corp HSS-L2D-004 Parallel Embed Eol Resistor

Product Description

The MAGNASPHERE CORP HSS-L2D-004 is a parallel embed end-of-line (EOL) resistor contact designed for special application security and alarm circuits. EOL resistors are installed at the end of a supervised loop to allow a control panel to distinguish between a normal, open, or shorted circuit condition. This component ships as a single unit and is intended for use by alarm installers, low-voltage technicians, and security system integrators who require precise loop supervision with resistors embedded in the contact assembly itself.

This part is suited for special application contact installations where an EOL resistor must be embedded directly into the magnetic contact rather than wired externally. This approach reduces field wiring time and minimizes the risk of resistor bypass or tampering. It is commonly used in commercial and residential intrusion detection systems where supervised loops are required by code or monitoring station standards.

Key Features

• Parallel EOL resistor embedded directly in the contact for supervised loop operation
• Eliminates the need for externally wired EOL resistors at the contact point
• Reduces potential tamper or bypass points in the supervised circuit
• Single-unit packaging for straightforward inventory and installation
• Classified as a special application contact for demanding installation scenarios

Compatibility

Designed as an OEM-style replacement or direct-use component for special application magnetic contact installations requiring parallel embedded EOL resistor functionality in supervised alarm loops.

Installation Notes

Installation should be performed by a licensed low-voltage or alarm technician in accordance with applicable local codes and NFPA 731 guidelines. De-energize the alarm loop and disarm the panel before removing or installing any contact. Verify control panel EOL resistor value requirements before installation, as mismatched resistance values will generate supervisory faults. Do not substitute this component with a standard non-EOL contact without updating the panel supervision settings.
