When you're responsible for large, multi-building premises, fire alarm monitoring is a key part of your job. Think of expansive university campuses, bustling city infrastructures, strategic military bases, or transit hubs. The importance of fire alarm systems grows with each additional building and each additional occupant.

Multiple Incompatible FACPs Can Be A Challenge

Fire safety is crucial for any building or space. A big part of this safety comes from fire alarm control panels (FACP). Imagine having many different FACPs, each with its own special alarm sound. It’s like trying to understand a group where everyone speaks a different language.

You Can't Replace Your FACPs All at Once

Your problem is that each FACP sends out different types of alerts. When you have a lot of them, it's hard to keep track of all these different formats. Ignoring these alarms isn't an option because they're all important.

But replacing all the FACPs at once is too expensive. So, we're stuck in a tricky scenario.

You Need Both a DACR with Broad Compatibility and a Proprietary Alarm Monitoring System

How do we solve this problem of monitoring multiple brands of FACPs, including those that dial on POTS lines, with one alarm system?

The solution to this problem lies in employing a Digital Alarm Communicator Receiver (DACR) that supports multiple Digital Alarm Communicator Transmitter (DACT) formats. This type of DACR can integrate alarms from various FACPs, irrespective of their unique alarm signals.

It interprets all the different DACT formats, translating them into a single, standardized output, making the monitoring process significantly more manageable. This approach not only ensures compatibility across varied systems but also offers a cost-effective alternative to the mass replacement of FACPs.

This is how a multi-format DACR enhances the efficiency and reliability of fire alarm monitoring systems in large, multi-building premises.

DDI-11E DACR and Prism LX: Your Solution for Monitoring Multiple FACP Brands

Enter the DDI-11E DACR and Prism LX. This innovative solution offers the capability to process alarms from multiple DACT formats, thereby simplifying your comprehensive fire alert systems.

You'll have no more juggling between different alarm formats and types - the DDI-11E DACR and Prism LX bring everything under one roof, ensuring that no vital alert goes unnoticed.

The integration of these systems offers a cost-effective and highly reliable solution to effectively manage and track alarms across different FACPs.

What Can This DACR and Proprietary Monitoring System Do For You?

A closer look into the connection between DDI-11E DACR and System 3505 Prism LX reveals compatibility with a diverse range of Digital Alarm Communicator Transmitter (DACT) formats. This extensive support ensures that no matter the alarm system in place at your facility, the integration is smooth and seamless. Here are some specific advantages:

  1. Silent Knight/Ademco Formats: The DDI-11E supports both slow (10 BPS) and fast (20 BPS) formats from Silent Knight/Ademco. This encompasses the 3/1, 4/1, 4/2, extended, and non-extended configurations. This flexibility ensures that older or varied Silent Knight installations can easily be incorporated.
  2. Sescoa, Franklin, DCI, and Vertex: With support for both 20 BPS 3/1, 4/1, 4/2 non-extended, and the 20 BPS 3/1 extended formats, facilities utilizing systems from these manufacturers can easily and effectively connect with the System 3505 Prism LX.
  3. Radionics Integration: DDI-11E is comprehensive in its Radionics format support, ranging from non-extended, non-extended with parity, to extended formats. This means even more specialized Radionics configurations can be smoothly integrated, enhancing the security infrastructure's robustness.
  4. Silent Knight's Contact ID: Known for its precise and speedy data transmission, the Contact ID format from Silent Knight is fully supported, ensuring that facilities with this advanced system experience seamless integration.
  5. Support for Specialized Formats: From FBI-Superfast, which is known for its speed, to the intricate BFSK and the established Modem 111-2A, the DDI-11E's extensive support list ensures that even niche systems can be efficiently incorporated into the System 3505 Prism LX™ environment.
  6. Future-Proofing with SIA Support: As industries shift towards the Security Industry Association (SIA) standards for alarm systems, the support for SIA by DDI-11E ensures that your facility is ready for both current and future configurations.

Incorporating such a wide array of DACT formats means that the DDI-11E and System 3505 Prism LX gives you a lot of versatility for your installation.

Whether your facility is operating on older systems and/or looking to integrate newer, more advanced formats, this setup ensures that all alarms can be received, enhancing safety and security.

Benefits of the DDI-11E DACR

The DDI-11E is a great solution for a variety of installations for these reasons:

  1. Bespoke Compatibility for Diverse Locations: Do you have a sprawling university campus, a vast transit agency, a fortified military base, an entire city, or any other entity tasked with fire alarms? The DDI-11E provides seamless integration.
  2. Tackling Common Misconceptions: Many hold onto myths about FACP monitoring – such as the need to always opt for third-party services because "that's how it's always been done," or believing internal teams lack the expertise to manage monitoring. DDI-11E elegantly dismantles these myths. It emphasizes that, with the right tool, in-house monitoring isn't just possible - it's efficient and cost-effective.
  3. A Commitment to Modern Monitoring Techniques: While many systems still rely on conventional non-addressable panels, DDI-11E embraces the benefits of newer addressable panels. With it, not only do you know when an alarm is triggered, but you'll also pinpoint exactly which component set it off, slashing critical response time.
  4. Power Redundancy, Ensuring Consistent Operations: Recognizing the absolute necessity for uninterrupted functionality in life-safety systems, DDI-11E is designed with redundant power sources. So, even in rare and unforeseen circumstances, alarm data can keep flowing.
  5. User-Centric Approach for Diverse Demographics: With the changing workforce and newer generations stepping into roles, DDI-11E is designed to be intuitive and straightforward. Regardless of an individual's prior experiences with FACP monitoring, this system simplifies the learning curve.
