Our Process

Since its founding in 1964, Advanced Safety Systems Integrators (ASSI) has established a proven track record of innovation, reliability and solutions-based service. As pioneers in the fire protection industry, we have been among the first in the industry to combine products such as clean agent systems, advanced smoke detection technologies and water mist systems to give our customers the best level of protection technology can provide.

Our history demonstrates the importance of ASSI to the industry. We installed the first Halon 1301 system in a computer room at Harvard University in 1967 and were a part of the group that pioneered the idea, design and application working with Dupont who was making Halon, and with Fenwal, the equipment manufacturer.

We were involved in the early design of VESDA (Very Early Smoke Detection Apparatus), and were also the first North American distributor of Marioff HI-FOG® water mist systems which opened the door to using water mist for cultural buildings, historical documents, irreplaceable artifacts and museums. ASSI has a history of delivering innovative fire protection solutions. We are also known for our loyalty to the manufacturers we have aligned with and to our customer base. Over the years, we have worked with small regional firms to Fortune 50 companies. Regardless of the business size, our goal is the same – we want to earn the trust of our clients, maintain long-term relationships, and keep them as customers for life.

The ASSI Process

The ASSI Process is a proven system that ensures seamless transitions from the design phase, to the development and maintenance of your fire protection systems. The iterative steps always begin with safety. Every site visit includes a Job Safety Analysis that involves everyone working on the job.


1. Design

Using the latest industry research and technology, ASSI designs fire protection and security solutions to meet your specific challenges. From standalone systems to integrated platforms, ASSI has a customized solution that will ensure the safety of your people and your property.

2. Installation

Our field staff consists of factory-trained and certified professionals who are ready to tackle the most challenging installation environments safely and efficiently. From busy healthcare facilities and heavy industrial and commercial applications to offshore oil rigs, we’ve got you covered.

3. Commission

Your safety is our top priority. Before we “hand over the keys” to your new fire protection system, ASSI performs rigorous testing to ensure the system meets the stringent guidelines set forth by the National Fire Protection Association, Coast Guard, American Bureau of Shipping and other approval agencies.

4. Customer Training

Once your new system is in place, our experienced team of technicians will train your team specifically on how it works and what is needed to keep it running at the optimal level. We are here to support you and the system every step of the way so that you can rest assured your people and property are safe.

5. Inspection

Your system will need to be inspected periodically. We are here to make sure that happens without delay so that you never have to wonder if safety has been compromised. Whether you have a ASSI-designed system or a system installed by another contractor, we will survey your facility, take an inventory of your fire protection equipment/systems and enter that information into our service management platform to ensure we never miss an inspection deadline.

6. Repair

Should repairs be needed following an inspection, you will be notified immediately. A properly functioning system is essential to safely protecting lives and property. Our technicians are trained not only to spot system deficiencies, but also to effectively provide a solution to the problem.

7. Technology Upgrade

As with all technology, advancements happen every day and with fire safety and security systems, it is no different. When your system is no longer meeting industry standards, we will alert you and provide you with options for ways to upgrade your system. Our number one goal is to keep our clients safe and secure.


Enhancing the Customer Experience

Why Now?

Other than loss of life or property from fire, the next biggest risk to your business is being shut down or fined for non-compliance. When ASSI was founded in 1964, compliance, service and maintenance were more difficult to manage because technological service innovation culminated in effective note taking and filing systems. So, the use of cutting-edge technology to manage customers’ fire protection and security needs was rather limited. Now, more than 50 years later, ASSI is proud to utilize the latest technology to manage your accounts.

What’s in it for you?

Knowledge is power. And, as your partner in fire protection, that’s what we seek to give you – the knowledge to make informed decisions about your fire protection systems. We make sure you stay informed every step of the way. You will receive:

  • Assurance that your routine inspections and services will be completed on time.
  • Validation that the work that you hired us to do was completed to our high standards and to code.
  • After-service access to our customer service team to answer any questions and schedule subsequent service or maintenance.

How does it work?

We collect service information before, during and after each service appointment and inspection. Once you schedule your appointment, an experienced ASSI technician will review your records to ensure he or she is equipped to provide you with the needed service.

During the service call, that same technician collects information and keeps you updated about the status of your facility. You may then review a work acknowledgment with the technician at the end of the job to discuss what the technician saw and did as well as any deficiencies that may have arisen.

We will provide quotes for repairs and include all of the media collected for you to review and approve. Once a quote is approved, the job will be scheduled at your convenience.

All around New England, ASSI products and installations are protecting lives and property. We are proud to safeguard everything from small businesses to large financial institutions. No matter how large or small, we will use the same technology and high level of professionalism across every market.
