Seco-Larm SD-72081-6MQ Single-Gang Mortise Cylinder Key Switch

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