SECO-LARM SD-72081-6MQ — ENFORCER Single-Gang Mortise Cylinder Key Switch

Full instruction manual for the SECO-LARM ENFORCER SD-72081-6MQ Single-Gang Mortise Cylinder Key Switch, a keyed backup override for electronic locks and access control systems.

Introduction

If a keypad or proximity card reader fails to activate an electronic lock, the user can switch between normally closed (N.C.) and normally open (N.O.) contacts using the SD-72081-6MQ to force the door open. This acts as a backup for access control systems, so the system does not rely on the integrity of a single device.

Features

• Keyed mortise cylinder (2 keys included).
• Mortise cylinder removable for ease of keying.
• Flush mount with vandal-resistant screws.
• Chrome-plated aluminum back plate fits a single-gang box.
• Stainless-steel front cover conceals mounting screws.
• DPDT momentary switch, 5A@125VAC contact rating, color-coded wires.

Specifications

Parts List

• 1x Front cover
• 1x Back plate
• 1x Set of keys (2 pc) — important: no replacement keys are available; make extra copies of your keys.
• 2x Vandal screws
• 1x Security wrench

Installation

1. Remove the back plate from the unit.
2. Thread the cable wire through the electrical box and the center hole of the back plate.
3. Connect the wires to the switch using the wiring diagram.
4. Fasten the back plate to the electrical box using the included mounting screws.
5. Finish assembly by snapping the front cover onto the back plate.

Wiring Diagram

Two switch outputs, each with color-coded N.C./COM/N.O. leads:

• Output 1: Blue = N.C., Green = COM, Yellow = N.O.
• Output 2: Black = N.C., White = COM, Red = N.O.

Sample Application

An electromagnetic lock (e.g. E-941SA-600) connects to the normally closed (N.C.) side of one switch output on the SD-72081-6MQ. A strobe light (e.g. SL-1301-BAQ) connects to the normally open (N.O.) side of the other switch output. Activating the SD-72081-6MQ switch unlocks the electromagnetic lock and triggers the strobe light simultaneously.

Compliance Notice

Users and installers are responsible for ensuring the installation and configuration complies with all national, state, and local laws and codes related to locking and egress devices.
