Securitron UnLatch Motorized Strike, MUNL 630 US32D Satin Stainless Steel for Mortise Locks 24VDC

Mortise UnLatch Strike
Mortise UnLatch is for any application where an electric strike would be used for a mortise type lock. The Mortise UnLatch includes field adjustability for latch and deadlatch positions, releases under pressure and includes a latch status monitoring output.

FSUNL Option: FSUNL allows the MUNL to become selectable for either "Fail Safe" or "Fail Secure" operation.

Note: UNL requires three wires for operation - continuous positive DC, continuous negative DC, and a trigger input to unlock.
