When emergencies happen, reliable communication isn’t optional.

That’s where an Emergency Responder Radio Communication System (ERRCS), also known as a Public Safety Distributed Antenna System (DAS), comes in. These systems ensure first responders can communicate clearly inside buildings like hospitals, high-rises, schools, and large venues.

To make these systems easier to deploy and manage, try Westell's ProtectLink Next Gen Fiber BDAs.

Here are four reasons installers are choosing ProtectLink Next Gen:

✔ Compact & Lightweight
Small form factors (as low as 15 lbs) make installs faster and easier.

✔ No Licenses or Fees
Class A or Class B operation with no ongoing costs.

✔ Reliable Public Safety Coverage
700/800 MHz dual-band support ensures strong, consistent communication.

✔ Designed for Compliance
Supports NFPA and UL-listed ERRCS requirements to help streamline AHJ approval.

There’s more to explore...including scalability, engineering support, and future-ready capabilities.

When it comes to fire alarm systems, choosing the right technology isn’t just a technical decision. It’s a critical factor in safety, efficiency, compliance, and long-term performance.

🔹 Conventional systems are a cost-effective, reliable option for smaller applications. They group devices into zones, giving you a general idea of where an alarm is triggered.
🔹 Addressable systems take it a step further with pinpoint accuracy. Ideal for larger, more complex facilities where speed and precision are critical.

👉 So which is right for your project?

Small Office Building Installations🏢
A 2-story office with a few conference rooms? A conventional system is often the right fit—simple, reliable, and cost-effective, with zoning that keeps installation straightforward.

Healthcare Facility installations 🏥
Hospitals demand speed and precision. An addressable system pinpoints the exact device in alarm, helping teams respond faster and more effectively in critical situations.

Retail Mall Installations 🏬
With multiple tenants, an addressable system allows you to identify exactly which store is in alarm, minimizing disruption and enabling targeted response.
