Triton door latch ZACZEP ELEKTRA R5 with memory and symmetric lock narrow 16.5 mm

Triton ZACZEP ELEKTRA R5 with memory and symmetric lock narrow 16.5 mm is a compact electric door latch designed for installations where a slim, reversible latch is required. The narrow 16.5 mm body allows integration into doors with limited edge space, and the symmetric locking mechanism supports use on doors that open inward or outward. The memory function keeps the latch in a defined state after activation, making it suitable for controlled entry systems and electrical strike installations.

Advantages

The latch combines a narrow housing with a symmetric blocking mechanism so it can be mounted on either side of a door without modification. The built-in memory function provides reliable retention of the latch state after an electrical pulse, reducing the need for continuous power. Its compact construction supports retrofit and new-build applications where space is restricted, and the design is compatible with common access control and entrance door setups.

Suitable for

• Access control systems in residential and commercial buildings
• Entrance and interior doors with narrow door edge profiles
• Electrical strike installations requiring reversible latch action
• Doors that need a memory-retained latch position after activation

Key specifications

• Body width: 16.5 mm (narrow profile)
• Locking type: symmetric block suitable for inward or outward opening doors
• Function: electric latch with memory (retained state after activation)
• Compatibility: designed for electric locking and strike assemblies
• Mounting: reversible installation on either door side

How to use

Install the Triton ZACZEP ELEKTRA R5 into the door frame or strike cavity following the door manufacturer’s guidelines and local electrical codes. Connect the latch to the access control or power supply so that it receives the required activation pulse for the memory function. Ensure correct alignment with the door striker plate and verify the symmetric blocking engages properly for both inward and outward opening directions. After installation, test the memory retention by applying an activation pulse and confirming the latch remains in the intended state.

Usage recommendations

For reliable operation, use in combination with compatible access control hardware and ensure power supply matches the latch’s electrical requirements. Periodic inspection of alignment and fastening is recommended, especially in high-traffic doors. If used in retrofit projects, confirm sufficient door edge clearance for the 16.5 mm body and adjust striker plate position as necessary.
