Magnasphere Corp HSS-L2D-011 Dual Contact Switch Level 2

Product Description

The MAGNASPHERE CORP HSS-L2D-011 is a dual-contact magnetic switch rated at Level 2 and configured with both normally open (N/O) and normally closed (N/C) outputs, plus an integrated tamper circuit. Designed for special application contact installations, this switch provides simultaneous N/O and N/C signaling in a single unit, reducing the need for multiple devices in security and access control wiring schemes. Licensed security and low-voltage alarm technicians are the primary installers. The tamper feature adds an additional supervisory circuit that alerts monitoring systems if the device is disturbed or removed from its mount.

The HSS-L2D-011 is suited for specialized security and access control applications where dual-contact switching is required. Level 2 classification indicates performance and construction standards appropriate for monitored intrusion detection systems. Typical installations include protected entry points, secure enclosures, and access-controlled doors where both a primary contact circuit and a tamper-supervisory circuit must be maintained simultaneously. This part is sold as a single unit (EA).

Key Features

• Dual-contact design provides both N/O and N/C outputs from a single device
• Integrated tamper circuit adds supervisory monitoring capability
• Level 2 rated construction for monitored security system applications
• Special application contact category for demanding or non-standard installation environments
• Single-unit (EA) packaging for straightforward procurement and replacement

Compatibility

Designed as an OEM-style replacement or direct installation component for special application contact systems requiring Level 2 dual-contact switches with tamper output.

Installation Notes

Installation should be performed by a licensed low-voltage or alarm systems technician in accordance with local codes and NFPA 731 guidelines for premises security equipment. De-energize and disarm the associated alarm or access control panel before wiring or replacing this device. Verify that the control panel or input module supports dual-contact and tamper circuit inputs before completing the connection. Do not defeat or leave the tamper circuit unconnected, as this may generate a supervisory fault at the monitoring panel.
