Ecoflex electrified mortise locks dramatically reduce energy consumption, resulting in lower operating costs and fewer power supplies. In addition, they offer a reliable, flexible and versatile locking solution, with a common lock for 12 – 24V applications, which can easily be field configured to fail-safe or fail-secure operation

About this item

The Sargent 8270 is the fail safe electromechanical mortise lock from Sargent's 8200 series. If you've been searching "sargent 8270", "sargent electric mortise lock", or "8270 part number specifications" - the 8270 designation codes this way: 82 identifies the 8200 series mortise lock platform, and 70 is the function designation for fail safe electrical operation. This is the same 8200 lockcase body used across Sargent's commercial line - with the electromechanical solenoid mechanism integrated inside the same door prep.

 

Fail Safe: What Function 70 Means at the Door

 

Fail safe means the lock defaults to the unlocked state when power is removed. With power ON, the solenoid energizes and locks the outside lever - the outside lever is rigid and won't retract the latch. A key in the outside cylinder can still retract the latch when locked. Inside lever always retracts the latch freely. When power is removed - during a power outage, fire alarm trigger, or system shutdown - the outside lever becomes free and the door can be opened without a key from either side.

 

This is the correct specification for egress doors where life-safety codes require the door to be freely passable during a fire alarm or power failure: stairwell re-entry doors, hospital exit corridors, and access-controlled doors on required means of egress. The door is electronically secured when the system is running and automatically releases when it fails.

 

Fail secure (the 8271) is the opposite: locked when power is off, free when energized. For secure areas like server rooms where a power outage should not unlock the door, fail secure is the specification. The 8270 and 8271 share the same body and door prep - the solenoid configuration is the difference.

 

EcoFlex Technology: 96% Power Reduction

 

Every 8270 includes Sargent's EcoFlex power management technology, GreenCircle certified to reduce power consumption by up to 96% compared to conventional electrified mortise locks. EcoFlex manages the solenoid current - using full current only for the brief moment of state change, then dropping to a holding current fraction. This reduces heat generation, extends solenoid life, and dramatically reduces power supply sizing requirements. A power supply that would need to serve multiple conventional electric locks can typically serve many more EcoFlex-equipped 8270s on the same circuit.

 

12-24VDC Voltage Range and Access Control Integration

 

The 8270 operates across the full 12 to 24VDC range. Most commercial access control power supplies output 12VDC or 24VDC - the 8270 accepts either without requiring a specific supply voltage. For stand-alone applications, it wires directly to a power supply and a door controller. For integrated access control, it connects to card readers, keypads, biometric readers, and credential management systems. The RX option (prefix RX-8270) adds a request-to-exit switch that monitors inside lever rotation, providing a signal back to the access control system when someone exits - useful for audit trails and anti-passback configurations.

 

Cylinder Options and the 60/70 Prefix

 

The standard 8270 uses conventional cylinder with LA keyway. Two IC core variants expand the options. The 60-8270 is prepped for Sargent LFIC (Large Format Interchangeable Core), sold less core. The 70-8270 is prepped for SFIC (Small Format Interchangeable Core), sold less core. IC prep versions are specified for facilities running an IC key system campus-wide - cores are managed and rekeyed with a control key without disassembling the lock.
