The Arrow AM17 24V NFS Electrified Mortise Lock Body is a heavy-duty commercial locking mechanism designed for integration with 24-volt electronic access control systems.

Featuring 24VAC/DC operation, fail-secure exterior knob control, Grade 1 mortise lock construction, and a standard 2-3/4" backset, the Arrow AM17 provides dependable electronic locking for commercial and institutional doors.

Part of the Arrow AM Series, this electrically controlled mortise lock body allows authorized access through compatible card readers, keypads, access control panels, and security systems.

Its fail-secure operation keeps the exterior knob locked when electrical power is removed. When the appropriate 24V electrical signal is applied, the exterior knob unlocks, allowing an authorized user to retract the latch and enter.

The interior knob remains mechanically free for egress regardless of electrical power status.

Operating on 24VAC or 24VDC at 330 mA, the AM17 24V NFS provides a commercial access control solution for facilities requiring exterior security during a power interruption.

Constructed with a heavy-gauge steel lockcase, zinc-dichromate corrosion-resistant coating, stainless steel latchbolt, and field-reversible handing, this lock body is engineered for durability and professional installation.

Designed for use with compatible Arrow AM Series knob trim, the AM17 can be incorporated into properly prepared hollow metal or wood doors.

Typical applications include office buildings, educational facilities, healthcare properties, warehouses, government facilities, and other secured commercial environments.

Important: This listing is for the electrified mortise lock body only. Knob trim, mortise cylinder, faceplate, strike, mounting screw pack, and external power supply are separate components.

Fail-Secure Locking Function

The AM17 24V NFS is designed to maintain exterior security when electrical power is interrupted.

Power OFF

• Exterior knob remains locked.

• Interior knob remains free for egress.

• Compatible mechanical key override remains available when installed.

Power ON

• Exterior knob unlocks.

• Authorized entry is permitted through normal knob operation.

• Interior knob remains free for egress.

This provides a practical solution for controlled entrances requiring the outside locking function to remain secured during a power failure.

Free Interior Egress

• Inside knob remains mechanically operable.

• Exit operation does not depend on electrical power.

• Maintains the designated mechanical egress function.

• Exterior access control operates independently.

The complete door assembly must still satisfy applicable building and life-safety requirements.

Commercial Access Control Compatibility

The Arrow AM17 can be integrated with compatible:

• Card reader systems

• Proximity access systems

• Commercial keypad controllers

• Access control relay panels

• Authorized entry switches

• Building security systems

• 24V access control power supplies

The lock body does not independently store user codes or credentials. Authorization is controlled by the connected access control equipment.

Standard Commercial Mortise Preparation

• Standard 2-3/4" backset.

• Designed for standard 1-3/4" thick doors.

• Heavy-duty mortise lockcase.

• Standardized AM Series case dimensions.

• Suitable for compatible commercial door preparations.

• Field-reversible handing.

Mechanical Key Override

When assembled with the appropriate trim and compatible mortise cylinder, the lock permits mechanical key override of the electronically controlled exterior locking function.

This allows designated authorized personnel to gain access independently of normal electronic operation.

Stainless Steel Latchbolt

• Two-piece stainless steel latchbolt.

• Anti-friction insert.

• 3/4" latchbolt throw.

• Auxiliary deadlocking latch.

• Designed for dependable commercial door latching.

Field-Reversible Handing

• Supports conventional commercial door handing configurations.

• Can be reversed following Arrow's approved procedure.

• Reduces replacement inventory requirements.

• Final handing must be verified during installation.

Optional Monitoring Configurations

Other AM17 factory configurations may provide:

RE – Request-to-Exit Monitoring

Detects authorized operation of the inside trim through a monitoring switch.

LM – Latchbolt Monitoring

Monitors the full extension of the latchbolt.

SM – Security Monitoring

Monitors locking and latch status using the specified monitoring arrangement.

Important: The standard AM17 24V NFS does not include these optional monitoring switches. Order the appropriate factory variant if monitoring is required.

How the Arrow AM17 24V NFS Works

1. Door Secured

With electrical power removed, the exterior knob remains locked.

2. Credential Presented

An authorized user presents a credential to a compatible access control reader or enters an authorized PIN at a connected keypad.

3. Access Authorization

The access control system verifies the credential and activates the appropriate control relay.

4. Power Applied

The control circuit supplies the specified 24V power to the electrified lock body.

5. Exterior Knob Unlocks

The exterior knob becomes operable, allowing the authorized user to turn the knob and retract the latchbolt.

6. Door Entry

The user opens the door during the access control system's programmed release interval.

7. Power Removed

After the authorized access period, the control system removes power from the lock.

8. Exterior Security Restored

The exterior knob returns to its locked condition.

9. Interior Egress

At all times, the interior knob remains mechanically free for exit.
