Lockwood ES8100 V-Lock Electric Strike Fail Safe / Fail Secure Monitored 11.4-28VDC

Product SKU: ES8100

Product Overview

The Lockwood ES8100 V-Lock Electric Strike Fail Safe / Fail Secure Monitored 11.4-28VDC is a high-performance motorised electric locking solution designed for modern access control installations. Engineered for commercial and institutional environments, the ES8100 provides powerful locking strength combined with advanced monitoring and flexible installation options. Its motorised V-Lock design allows the door to lock securely even when under preload pressure, making it ideal for doors exposed to side load, misalignment or heavy daily use.

Why Choose the ES8100

The ES8100 V-Lock is designed to solve common door locking challenges such as door misalignment, side pressure and high-traffic usage. Its motorised locking mechanism can unlock even when significant pressure is applied to the door, which helps maintain reliable access control in real-world environments. The lock also offers integrated monitoring for both door position and lock status, providing improved system visibility for security management. With flexible fail safe or fail secure configuration and weather-resistant construction, the ES8100 is a versatile solution for professional door security installations.

Key Capabilities

Key Features

• 1000kg Holding Force: The ES8100 provides a very high holding strength designed for demanding commercial applications where strong mechanical locking is required.

• Pre-Load Release Capability: The lock can unlock even when the door is under significant side pressure, allowing reliable operation on doors that experience preload from seals, airflow or misalignment.

• Door Position and Lock Status Monitoring: Monitoring outputs provide signals to access control systems indicating whether the door is closed and whether the lock is fully engaged.

• Integrated LED Diagnostics: On-board LED indicators provide visual feedback for installers and technicians, helping with system diagnostics and status verification during installation or maintenance.

• Weather Resistant Construction: The lock features an IP53 rated design suitable for many external door environments where protection from dust and moisture is required.

• Flexible Mounting Options: The ES8100 can be mounted vertically or horizontally and supports optional mounting accessories for glass or surface-mounted installations.

FAQs

1. What makes the ES8100 different from standard electric strikes?
   The ES8100 uses a motorised V-Lock mechanism rather than a traditional strike release design. This allows it to unlock even when the door is under pressure or slightly misaligned, which is a common issue with standard electric strikes. This makes it particularly useful in environments where doors are exposed to wind pressure, heavy seals or structural movement.
2. What does fail safe and fail secure mean for this lock?
   Fail safe means the lock releases when power is removed, which is often used for doors that must unlock during power failures for safety reasons. Fail secure means the door remains locked when power is removed and unlocks only when power is applied. The ES8100 can be configured to either mode during installation.
3. What does monitored mean for this V-Lock?
   A monitored lock provides status signals to the access control system. The ES8100 can report whether the door is closed and whether the locking bolt is fully engaged. These signals allow the security system to detect faults such as doors not fully closing or locks failing to engage correctly.
