Tane Alarm sd-71b Recessed Door Contact 10 Pack

Product Description

The TANE ALARM sd-71b is a stubby-style recessed door contact and magnet set designed for steel door installations. The contact body measures 3/8 inches in diameter and the magnet measures 3/4 inches in diameter, with an operating gap of up to 1.5 inches. This pack includes 10 contact-and-magnet pairs, making it well suited for multi-door projects. The white finish blends with standard door frame finishes. Security installers and alarm technicians install this type of device as part of perimeter detection systems in residential and light commercial applications.

The sd-71b is intended for use in steel door and frame assemblies where a recessed, low-profile installation is required. The stubby form factor fits tighter boring depths than standard full-length recessed contacts, making it a practical choice when door thickness or frame depth is limited. The 1.5-inch gap rating provides reliable magnetic actuation even with minor door alignment variation. Sold in a 10-pack, it is commonly used by alarm contractors outfitting multi-entry commercial buildings or new residential construction.

Installation Notes

Installation is typically performed by licensed alarm or low-voltage security technicians. Bore the door and frame to the appropriate diameter before seating the contact and magnet. Ensure the door is fully de-energized from any access control hardware before drilling or wiring. Follow local low-voltage wiring codes and the alarm panel manufacturer's wiring guidelines when terminating leads.
