Setup and Installation

Proper installation is crucial for the optimal performance and security of your electric strike lock. This device is designed for mortise mounting within the door frame.

1. Pre-Installation Check

• Ensure the door frame has sufficient space for mortise installation.
• Verify the door's swing direction (inswing/outswing) and handing (left/right) to plan the installation correctly. The strike is reversible.
• Confirm you have a compatible mechanical lock or cylindrical lockset (not included) that will interact with the electric strike.
• Prepare necessary tools: drill, chisel, screwdriver, measuring tape.

2. Mortise Installation

The electric strike requires a mortise cut into the door frame. Refer to the dimensions provided in the Specifications section and the diagram below for precise measurements.

1. Mark the Area: Position the electric strike on the door frame where the latch bolt of your mechanical lock will engage. Mark the outline of the strike's faceplate and the mortise depth.
2. Cut the Mortise: Carefully chisel out the marked area to the required depth, ensuring a snug fit for the strike body.
3. Drill Pilot Holes: Drill pilot holes for the mounting screws as indicated in the diagram.
4. Insert Strike: Place the electric strike into the mortise. Ensure it sits flush with the door frame surface.
5. Secure: Fasten the strike to the door frame using the provided screws.

3. Wiring Diagram (Fail-Secure NO Mode)

The electric strike features a non-polarized 2-contact connection for simplified wiring. Connect it to your access control system or egress device as shown in the diagram below. The included diode should be wired across the terminals to protect against back-EMF (electromotive force) when the lock is de-energized.

• Connect the two wires from the electric strike to the appropriate output terminals of your 12V DC power supply or access control panel.
• Ensure the diode is correctly installed across the terminals of the strike, with the band on the diode matching the positive terminal of the power supply. This prevents damage to your control system.
• For Fail-Secure (NO Mode), the lock will be open (unlocked) when power is applied and closed (locked) when power is removed.

Operating Instructions

The YUHANUS Electric Strike operates in Fail-Secure (NO Mode). Understanding this mode is key to its operation.

• Locked State: In Fail-Secure (NO Mode), the electric strike is in its default locked state when no power is supplied to it. The door will remain secured.
• Unlocked State: To unlock the door, a 12V DC power signal must be applied to the electric strike. This energizes the solenoid, retracting the strike mechanism and allowing the door to be opened.
• Access Control Integration: When integrated with an access control system (e.g., keypad, card reader, biometric scanner), the system will momentarily apply power to the strike upon successful authentication, allowing entry.
• Egress: For exiting, a push-to-exit button or similar device connected to the access control system will also apply power to the strike, releasing the door.
• Power Interruption: In the event of a power failure, the electric strike will revert to its locked state, maintaining security.

Maintenance

Regular maintenance ensures the longevity and reliable operation of your electric strike lock.

• Cleaning: Periodically wipe the faceplate and visible parts with a soft, dry cloth. Avoid abrasive cleaners or solvents.
• Lubrication: Lightly lubricate the moving parts of the strike mechanism (e.g., the latch bolt receiver) with a silicone-based lubricant annually or as needed. Do not over-lubricate.
• Screw Tightness: Check all mounting screws periodically to ensure they are tight. Loose screws can affect performance and security.
• Wiring Inspection: Annually inspect wiring connections for any signs of wear, fraying, or corrosion. Ensure all connections are secure.
• Functionality Test: Regularly test the lock's operation with your access control system to ensure it unlocks and locks correctly.
