Dimensions

The lock components have the following approximate dimensions:

Installation Diagram Overview

The installation diagram illustrates the assembly of the lock components:

• Outside Lever Assembly
• Cylinder Assembly
• Spindle
• Rose Plate
• Inside Rose Cover
• Inside Lever
• Spindle Assembly
• Armor Front
• Lock Case
• Strike Plate
• Dust Box

Changing Fail-Safe/Fail-Secure Operation

To change between fail-safe and fail-secure modes:

1. Remove the cover plate at the bottom corner of the lock case.
2. Use the internal screw to set the desired operation. Position 1 typically indicates Fail-Safe, and Position 2 indicates Fail-Secure. (Factory default setting is fail-safe).

Lever Control

Default Setting: Two 3x8 screws are installed on both sides of the lock.

• With the 3x8 screw installed: Turning the inside/outside lever retracts the latchbolt and opens the door. Lever rotation is monitored.
• When the 3x8 screw is removed: Turning the inside/outside lever does not retract the latchbolt and cannot open the door. Lever rotation is unmonitored. The opening of the door is controlled by an access control device (e.g., card reader).

Note: When an access control device is used to open the door, turning the inside/outside lever still retracts the latchbolt, and lever rotation is monitored.

Changing Latchbolt Handing

To reverse the latchbolt direction:

1. Insert a flathead screwdriver into the hole on the back of the lock case.
2. Push the screwdriver forward; the latchbolt will move forward.
3. Rotate the screwdriver 180 degrees to reverse the latchbolt's direction.
4. Remove the screwdriver; the latchbolt will retract back into the lock case.

Optional Electrical Accessories

The power transfer door loop protects the running wires from the door frame to the door leaf.

Available options include:

• Armored Door Loop with End Caps
• Armored Door Loop with Removable Cover

Using the Crimp Connectors

To use crimp connectors:

1. Place the wire inside the connector.
2. Use pliers to press down evenly on the head of the connector.

Installing Cylinder and Armor Faceplate

1. Screw the cylinder into the threaded hole of the lock case.
2. Tighten the screw against the cylinder(s) by turning clockwise.
3. Install the faceplate onto the lock case front and fasten with supplied screws.

Note: Cylinder assembly is not included. The GML800 series requires a UL 437 lock cylinder.

Wiring Diagram

For 12VDC operation: Use the supplied electrical connector marked '12 VDC' and connect its red/black wires to the control device.

For 24VDC operation: Use the supplied electrical connector marked '24 VDC' and connect its white/black wires to the control device.

Typical Wiring for Fail-Safe Operation

This diagram shows a power supply (12/24 VDC) connected to an access control device, which then interfaces with the lock. The lock connection is labeled 'INPUT 12/24 VDC' and marked as 'Polarity Insensitive'.

Typical Wiring for Fail-Secure Operation

Similar to fail-safe, this diagram shows a power supply connected to an access control device and the lock. The lock connection is also labeled 'INPUT 12/24 VDC' and 'Polarity Insensitive'.

Dual Voltage (12V) Wiring

For 12VDC control devices, the wiring is:

• Black wire: Connects to the control device (+)
• Red wire: Connects to the control device (-)
• White wire: Connects to the 12 VDC power supply (+)
• Green wire: Connects to the 12 VDC power supply (-) (Polarity Free)

Dual Voltage (24V) Wiring

For 24VDC control devices, the wiring is:

• White wire: Connects to the control device (+)
• Green wire: Connects to the control device (-)
• Black wire: Connects to the 24 VDC power supply (+)
• Red wire: Connects to the 24 VDC power supply (-) (Polarity Free)

Wiring and Monitoring Instructions

Fail-Secure Mode Wire Configuration

• Blue: Normally Open (N.O.)
• Green: Common (COM.)
• Yellow: Normally Closed (N.C.)

Fail-Safe Mode Wire Configuration

• Blue: Normally Closed (N.C.)
• Green: Common (COM.)
• Yellow: Normally Open (N.O.)

Lock Monitoring

This output indicates the door's locked and unlocked status. When power is not applied, connect the wires as shown for monitoring lock status. Contact Rating: 1A/40VDC (resistive load).

Lever Monitoring (Request-to-Exit)

This output indicates lever rotation. When lever rotation is monitored, the latchbolt can be retracted by the lever for immediate exit. When the lever is not operated, connect the wires as shown for monitoring lever rotation. Contact Rating: 1A/40VDC (resistive load).

Door Status Monitoring

This output indicates whether the door is open or closed. When the door is open, connect the wires as shown for monitoring door status. Contact Rating: 1A/40VDC (resistive load).
