1. Install the Mortise Lock Body:

   Using the provided template, prepare the door for the mortise lock body. Insert the mortise into the door edge and secure it with screws. Ensure the latch direction is correct for your door's opening. The latch can be adjusted for inward or outward opening doors.

2. Install the Front Panel:

6. Operating Instructions

The Zemismart A270 offers multiple ways to unlock your door.

6.1 Initial Setup and Administrator Registration

Upon first use, you will need to register an administrator fingerprint or password. Refer to the specific instructions in the Tuya Smart app or the lock's voice prompts for this process. The administrator has full control over user management and lock settings.

6.2 Fingerprint Unlock

This image focuses on the semiconductor fingerprint head of the Zemismart A270 lock. It highlights the fingerprint recognition area on the handle and provides performance metrics: recognition speed of less than 0.5 seconds, false recognition rate of less than 0.001%, and false rejection rate of less than 0.01%. This demonstrates the lock's advanced biometric security.

1. Place your registered finger flat on the fingerprint sensor located on the handle.
2. The lock will emit a successful unlock sound or light indication.
3. Push down the handle to open the door.

6.3 Password Unlock

1. Touch the keypad to activate it.
2. Enter your registered password followed by the '#' key.
3. If the password is correct, the lock will unlock.
4. Optional: Use a random sequence of numbers before or after your actual password (anti-peep function) to prevent others from guessing your code.

6.4 IC Card Unlock

1. Place your registered IC card against the card reader area on the front panel.
2. The lock will verify the card and unlock.

6.5 Mechanical Key Unlock

This image illustrates two security features of the Zemismart A270 lock. The top left shows the keypad and a hand inserting a mechanical key into the lock. The bottom section highlights the internal security switch, with 'Off' and 'Unpack' states, indicating how to activate or deactivate the administrator security.

In case of battery depletion or electronic malfunction, the mechanical key can be used:

1. Locate the keyhole cover on the front panel (usually hidden).
2. Insert the mechanical key and turn it to unlock the door.

6.6 Administrator Security Switch

The internal security switch, located on the rear panel, provides an additional layer of security. When activated, only the administrator password or mechanical key can unlock the door from the outside. This prevents other registered users (fingerprint, IC card, regular password) from gaining entry. This feature is useful when you want to restrict access temporarily.

6.7 Tuya App Remote Unlock and Management

To utilize smart features, connect your Zemismart A270 lock to the Tuya Smart app via a Zigbee gateway (sold separately).

1. Download the "Tuya Smart" or "Smart Life" app from your app store.
2. Register an account and log in.
3. Add your Zigbee gateway to the app.
4. Follow the in-app instructions to add the Zemismart A270 lock to your gateway.
5. Once connected, you can remotely unlock the door, manage users (add/delete fingerprints, passwords, IC cards), view access logs, and adjust settings from anywhere.

6.8 Doorbell Function

The lock features an integrated doorbell. When a visitor presses the doorbell button on the front panel, the lock will chime. If connected to the Tuya app, you may receive a notification on your smartphone.

7. Maintenance

• Cleaning: Wipe the lock's surface with a soft, dry cloth. Avoid abrasive cleaners, solvents, or harsh chemicals that could damage the finish or electronic components.
• Battery Replacement: The lock will provide a low battery warning. Replace all 4 AAA batteries promptly to avoid being locked out. Use high-quality alkaline batteries.
• Mechanical Parts: Periodically check screws for tightness. Do not lubricate the lock cylinder or internal mechanisms with oil-based lubricants, as this can attract dust and cause issues.
• Firmware Updates: If available, update the lock's firmware via the Tuya Smart app to ensure optimal performance and security features.
