Frequently Asked Questions

Q: What is a two-door interlock relay module used for?

A: A two-door interlock relay module is used in access control systems to ensure that only one door can be open at a time. The second door will not unlock until the first door has been opened and fully closed, creating a secure sequential entry point — commonly used in banks, prisons, and high-security facilities.

Q: Is the two-door interlock relay module easy to install?

A: Yes. This interlock relay module is designed for straightforward installation and integrates easily with standard fail-safe electric locks that feature a signal output. Its compact size (69L × 60W × 15H mm) allows it to fit neatly into most access control enclosures.

Q: What types of locks are compatible with this interlock module?

A: This module is compatible with fail-safe electric locks that have a signal output. It operates at a maximum of 5A / 24V, making it suitable for a wide range of standard commercial and industrial electric lock systems.

Q: Can this module be used in temperature-variable environments?

A: Yes. The module is rated for operating temperatures between -20°C and +70°C and humidity levels of 5–90%, making it suitable for a broad range of indoor installation environments.
