Fermator Landing Door Lock K200 K300

Original Interlock System for Fermator Elevator Doors

Product Overview

The Fermator Landing Door Lock K200 K300 is an original interlock component used in Fermator elevator door systems. It is designed to ensure that the landing door remains securely locked unless the elevator car is correctly positioned at the floor.

In practical applications across regions such as Spain and the UAE, these lock models are commonly used as part of original Fermator installations. Unlike general replacement locks, Fermator models are typically selected to match the system configuration directly, ensuring proper alignment and reliable operation.

Because of its role in the safety circuit, this component is considered a critical part of the door system rather than a simple mechanical accessory.

Role in Safety System

The landing door lock is part of the elevator safety chain.

Its main functions include:

• preventing door opening when the car is not present
• ensuring proper locking before elevator movement
• transmitting safety signals to the control system
• coordinating with the door cam during unlocking

In Fermator systems, the lock is designed to work precisely with matched components.

K200 and K300 Models

The K200 and K300 versions are typically used in different configurations depending on:

• door structure
• installation dimensions
• system requirements

In original Fermator setups, selecting the correct model ensures proper mechanical engagement and signal operation without additional adjustment.

---

Difference from General Replacement Locks

Compared with non-original or general locks:

• Fermator locks → system-matched, original configuration
• generic locks → adaptable, but may require adjustment

Fermator models are typically chosen when:

• maintaining original system performance
• ensuring precise alignment with door cam
• avoiding compatibility issues

---

System Integration

This lock operates together with:

• Fermator door cam
• landing door structure
• control system safety circuit
• car door movement

Unlocking occurs only when the cam engages at the correct position.

---

Application Context

These lock models are commonly used in:

• Fermator elevator door systems
• passenger elevators
• residential and commercial buildings
• maintenance and replacement projects

In European markets such as Spain, technicians often prefer original locks to maintain consistent system behavior.

Performance Characteristics

In real-world operation, original Fermator locks provide:

• precise locking and unlocking timing
• stable safety signal transmission
• reliable operation under repeated cycles
• consistent performance with matched components

Because of system integration, performance depends on correct matching rather than standalone specifications.

---

Maintenance and Replacement

Technicians may inspect or replace the lock when:

• door fails to lock properly
• elevator does not operate due to safety circuit faults
• unlocking becomes inconsistent
• mechanical wear or misalignment appears

Using the correct model helps restore system stability without additional adjustment.

---

Practical Notes

From a service perspective:

• original locks are preferred for system consistency
• compatibility is more important than flexibility
• installation alignment directly affects performance

This distinguishes them from general replacement components.
