Ideal for Access Control Installations

The Lockwood EMZ4-SN is designed for reliable door locking in access control systems where a compact, non-monitored electromagnetic lock is suitable. It can be used with compatible access control readers, keypads, request-to-exit buttons, intercom systems and door controllers.

Its surface mount design makes it a practical option for both new installations and upgrades to existing security systems, especially where simple fail-safe locking is required.

Fail-Safe Security Operation

As a fail-safe electromagnetic lock, the EMZ4-SN releases when power is removed. This makes it suitable for many access control and emergency egress applications where doors need to unlock during power loss or fire system activation, subject to site requirements and compliance standards.

Compatibility Note

The Lockwood EMZ4-SN is a non-monitored maglock and does not provide lock status monitoring. If your installation requires lock monitoring or door status feedback, a monitored Lockwood electromagnetic lock model may be required.
