Technical Context

The SM-4201-LWQ monitors the magnetic relationship between an overhead door and its track-mounted contact. The wide-track design accommodates large installation gaps, while iridium-plated contacts provide durable switching performance in a closed-loop security circuit.

Installation Notes

Mount the contact and included bracket on the overhead-door track and align the magnet with the contact across the specified gap. Adjust the bracket for a 2-5/8 to 4-inch channel width, route the armored cable to the alarm panel, and maintain sealed connections appropriate for the IP65 installation environment.
