Fortress Interlocks Joins Machine Safety Alliance to Provide Machine Safety Knowledge

Safety Interlocking company Fortress Interlocks is a member of the Machine Safety Alliance with Festo, Pilz Automation Technology, Troax, UK Engineering, and Werma. The Machine Safety Alliance aims to share its collective knowledge and expertise to help machine builders and users make sense of safety and safeguard their productivity.

The Machine Safety Alliance brings together experts of the collective technologies under one roof to provide comprehensive safety knowledge that is more readily accessible.

Fortress Interlocks is a leader in access and control safety systems, designing and manufacturing safety interlocking systems, trapped key, key exchange, solenoid and non-solenoid guard switches and modular control devices that ensure safety by action in a pre-determined sequence.

Tony Baggott, Sales & Marketing Manager at Fortress Interlocks commented: “The Machine Safety Alliance is a non-profit organisation. Our hope is to help companies understand and comply with safety regulations while balancing productivity. Fortress Interlocks, as a market leader in safety access and control systems, is well placed to provide expertise in this field in collaboration with our specialist partners in the alliance.”

Double Door Interlock from Fortress Interlocks Regulates Access in Hygienic Areas

Fortress Interlocks has introduced the robust DMSK2 into its DM (Door Module) access interlock range. The DMSK2 is a standalone, stainless steel, double door interlock specially designed for hygienic areas and suitable for all types of doors. Its minimal, smooth design helps reduce dirt traps while protecting workers from hazardous areas. DMSK2 is ideal for use in the food industry and any applications requiring hygienic processes.


As part of an interlock system, DM locks are used to control access to enclosed areas until a safe condition has been achieved. In a typical operation sequence, the key is inserted into the lock and turned; the actuator is disengaged and the door opened. The key remains trapped until the door is closed and the actuator re-engaged. The DMSK2 double door interlock allows up to two trap keys.

The DM module benefits from a revolutionary head design which features a choice of 4 head rotation angles with an adjustment of 360° at 90° increments and 2 actuator entry points.

The head, all internal contact components, actuators and keys are constructed using stainless steel. Tested to over 1,000,000 operations, the units have tamper resistant head mechanisms, and require minimal maintenance.

Fortress Ensures Machine Safety with New Extracted Key Adaptor

Safety Interlocking company Fortress Interlocks has added its new E1, Extracted Key Adaptor, to the amGard range of modular safety gate switch interlocks. The E1 has been designed to ensure that the door to hazardous machinery cannot be opened without removing the safety key, and the machinery cannot then be restarted until the key is returned.

Fortress has achieved this by designing a mechanism that traps the actuator in the head until the key is removed which then allows the ‘gate’ to swing over the keyhole. While the actuator remains out of the head, the gate remains over the keyhole preventing the key being returned to the lock.

E1 ensures a specific sequence of operation and can be stacked or combined with other adaptors; up to 5 key adaptors can be used in one configuration. E1 also provides a unique link to Fortress’ high profile mechanical mGard range of interlocks.

E1 works with access key and safety key adapters, amGard LOK or STOP bodies and is suitable for either hinged or sliding door applications. The modular arrangement of amGard allows customers to tailor and configure products to suit their application. amGard is a heavy duty interlocking range that provides both safety and security by controlling access to dangerous machinery and safeguarding personnel. A variety of actuators and adaptable mounting arrangements helps sustain a long life cycle and minimises downtime.

New Modular Pneumatic Valve⁺ Interlock Range

Fortress has redeveloped its Pneumatic Valve+ (PV+) unit into a modular design that allows the configuration of an array of valves, trapped key interlocks and key switches in any combination.

The PV+ is suitable for the isolation of a pneumatic power source and is conventionally key-free, but the revised modular design allows the unit to be used in conjunction with other functional modules, giving the user flexibility.

The PV+ has been designed to complement the Fortress mGard range of mechanical key interlocks for heavy applications, which work by releasing and trapping keys in a predetermined sequence to ensure safe operation of dangerous machinery; access is not permitted until a safe condition has been achieved.

With the new PV+, a combination of isolation/access keys is possible, with sequential or non-sequential key operation available. Because mGard is designed to be modular, it is possible to add modules to create unique configurations. The PV+ has been designed with a zinc alloy valve body and mild steel zinc coated plates.
