Door Interlocking Systems

We Make Door Interlocking Easy – From Design to Operation

Door interlock systems control the entry and exit of personnel and material in secured areas. Two or more doors create an airlock, where only one door can open at a time to provide an added level of security and safety in a controlled environment. When used in sterile or sanitary applications, door interlocking can be used to manage airflow. It can preserve air purity and restrict contamination between rooms so that production quality is not impacted.

Sentry Interlocks consists of a team of experts with years of experience. We’ve developed a full ecosystem that addresses two long-standing issues in the industry: complexity and inflexibility. Request more information today to find out how simple installing an interlock controller can be.

Our Solution

Designing, building and installing a traditional door interlock system is complicated because there are many variables involved. Ensuring that the interlocking scheme between multiple doors allows the movement of personnel and material in a logical and safe fashion is challenging. From the mechanical side, there is a wide variety of door types, electric locks, door position sensors and door accessories that need to be integrated into a cohesive system. Incorporating access control, building management systems (BMS) and fire alarm systems adds yet another layer of complexity.

The Sentry Interlocks family of door interlocks provides a predesigned door control solution that is extremely simple to specify, order, program and install. You can start ordering the right system now.

We offer responsive and clear communication, attention to detail, follow-through and a focus on doing what is best for you. Our professional team offers interlock door systems that work and a partnership you can count on.
  • Speed:  Traditionally, door interlocking systems are designed from scratch, assembled in a job shop and are difficult to install using cumbersome wiring schemes. Initial installation and subsequent changes can require multiple technical support calls to get the system to work properly. Our modular system is based around a predesigned and preprogrammed module that lets you install easily and scale quickly, reducing your downtime and costs. Sentry Interlocks provides a detailed wiring schematic that clearly shows how to wire each module together. The terminals on each module are labeled so you know exactly which wire to attach where. Installation is straightforward and easy to follow.

Sentry Interlocks solutions help you control personnel and material flow across multiple secured doors with customizable options and fail-safe electric locks. Browse our products in-depth with our online resources.

DOOR INTERLOCK MODULES

Sentry Interlocks uses a predesigned, stand-alone module as the basis of design for the three types of interlocking solutions. This approach makes the design, implementation and field adjustment of your door interlock system quick and easy. The module design incorporates all aspects of field-proven door interlocking technology. The modules can ship preprogrammed to your locking scheme. Installation is easy with the use of plug-and-play cables and a minimum number of components to wire up.

While simple, the modular system is powerful. Easily set up a two-door interlock system or an entire facility system that can be operated remotely. You can even set up touchless entry.
