Smart electromechanical door lock | latch | 12V DC | automatic locking | unlocks when power is applied

Two mechanical cylinders – provide an additional option for mechanical unlocking with a key. Whether unlocking is possible from one or both sides of the door depends on the cylinder installation and the door construction.

This electromechanical lock is a Fail Secure version. With this operating principle, an electrical signal is used to unlock the lock, while in the event of a power failure the mechanism remains locked. This solution is commonly selected for applications where maintaining the locked state during a power outage is a priority.

Because the lock remains locked when electrical power is interrupted, the specific safety requirements and the intended method of emergency mechanical unlocking must be evaluated before using it on emergency exits, fire-rated doors or other special-purpose doors.

The lock has two mechanical cylinders, providing key-operated mechanical unlocking in addition to electrical control. This is useful during maintenance, in the event of a control system malfunction, or whenever the door needs to be operated independently of the intercom or access control equipment.

• Two mechanical cylinders provide an additional key-operated unlocking option.
• Fail Secure operation – the lock remains locked if electrical power is interrupted.
• Automatic relocking after approximately 5–8 seconds if the door is not opened after electrical unlocking.
• Fast unlocking – the manufacturer's catalogue specifies less than 1 second.
• Suitable for left- and right-hand doors.
• Suitable for inward- and outward-opening doors.
• Compatible with intercom and access control systems.
• 25mA standby current provides low power consumption in standby mode.
• More than 500,000 cycles declared mechanism service life.
• Iron body and lock bolt provide a robust mechanical construction.
• Nickel-plated finish provides a clean metallic surface appearance.

• Fail Secure design: the door does not automatically unlock during a power failure.
• An external 12V DC power supply is required for electrical unlocking.
• Precise mechanical installation is required: the lock bolt and strike plate must be correctly aligned.

The lock is installed on the entrance door of an office, apartment building or commercial premises and connected to a 12V DC power supply and an intercom or access control controller. When an unlock command is received, the lock electrically releases the mechanism in less than 1 second. If the door is not opened, it automatically locks again after approximately 5–8 seconds. If required, the lock can also be operated mechanically with a key via the cylinders. In the event of a power failure, the Fail Secure mechanism remains locked.

Yes. The lock has two mechanical cylinders and can be operated with a key. Whether unlocking is possible from one or both sides of the door depends on the cylinder installation and door construction.

It means that the lock incorporates two mechanical cylinders intended for mechanical key operation.

Fail Secure means that the lock remains locked if the electrical power supply is interrupted. Electrical power is used for the unlocking function.

The standby current is approximately 25mA.

The specified unlocking time is less than 1 second.

Yes. If the door is not opened after electrical unlocking, the lock automatically locks again after approximately 5–8 seconds.

Yes. It is compatible with building intercom and access control systems.

Yes. The lock is suitable for both door directions and for inward- or outward-opening doors.

The lock body dimensions are 130x105x39mm.

The operating temperature range is -20°C to +50°C.

More than 500,000 operating cycles.

The lock must be installed so that the body, lock bolt and strike plate are precisely aligned and the mechanism operates without binding. The power supply must provide a stable 12V DC supply and sufficient unlocking current. Because this is a Fail Secure lock, it remains locked during a power failure. Therefore, all applicable safety requirements must be evaluated before installation on emergency or evacuation exits.
