Magnasphere Corp HS-L1.5-201 Surface Contact UL634

Product Description

The MAGNASPHERE CORP HS-L1.5-201 is a UL634 Level 1 surface contact designed for use in burglar and intrusion alarm systems. It operates as a single open tamper-style magnetic contact, providing a normally-open circuit that triggers an alarm signal when the contact is disturbed or separated. This component is used in access point monitoring, including doors and windows, in both residential and commercial security installations. Licensed alarm installers and low-voltage security technicians are the primary trade professionals who specify and install this device.

The HS-L1.5-201 is suited for surface-mount applications where a concealed or recessed contact is not practical or required. It is used in UL-listed alarm panel installations that require UL634 Level 1 compliant components throughout the sensing circuit. Typical deployment covers hinged doors, sliding doors, and window frames in commercial buildings, multi-tenant residential facilities, and institutional security projects where code-compliant component certification is a specification requirement.

Key Features

Installation Notes

Installation should be performed by a licensed low-voltage security technician in accordance with local alarm licensing requirements and applicable electrical codes. De-energize and disarm the alarm panel before wiring the contact into the sensing loop. Verify correct circuit supervision polarity and end-of-line resistor requirements per the panel manufacturer specifications before commissioning.
