Public Safety DAS and ERCES for Topeka Buildings
Tech Electronics designs, installs, tests, and maintains Public Safety Distributed Antenna Systems in Topeka that give police, fire, and EMS reliable two-way radio coverage inside your building. Also known as ERCES, ERRCS, and BDA systems, these are life safety systems, and when a first responder keys a radio in a stairwell or a basement, the signal has to be there. Our NICET and FCC GROL-certified team handles the whole process, from the initial signal survey through code-compliant design, installation, and final AHJ acceptance testing.

Professional Public Safety DAS and ERCES Installation in Topeka, Kansas
For over 63 years, Tech Electronics has served businesses and institutions across the Midwest. Our Topeka office on Bleckley Street, established in 2017 through our acquisition of Professional Fire Alarm Systems, Inc. (PFAS), builds on a life safety legacy already trusted in the region. Our team supports clients in Downtown Topeka, the Topeka Boulevard and Wanamaker Road corridors, state government facilities, and throughout Shawnee County with in-building public safety communication systems engineered to pass inspection and perform when it counts.
This technology goes by many names. You may hear it called a Public Safety DAS, an Emergency Responder Communication Enhancement System (ERCES), an Emergency Responder Radio Coverage System (ERRCS), a bi-directional amplifier (BDA) system, or simply PS DAS. They all describe the same purpose: amplifying and distributing public safety radio signals throughout a building so first responders stay connected.
Whether you need a single bi-directional amplifier for one building or a fiber-fed active DAS coordinated across a multi-floor, multi-building campus, our solutions scale to the structure and to the code that governs it.
Every system we design begins with a signal survey and ends with the documentation your Authority Having Jurisdiction (AHJ) needs to grant occupancy, plus the ongoing inspection and monitoring that keep it compliant year after year.

Advanced Public Safety DAS Technology Solutions
At Tech Electronics, we engineer each Public Safety DAS around your building’s construction, its measured signal conditions, and the public safety radio network it has to reach. A complete system brings several components together.
Signal Source and Donor Antenna
Every ERCES starts with a clean connection to the local public safety radio network. A rooftop donor antenna, carefully aimed and isolated, captures that signal and feeds it into the system. Getting this right is the foundation for reliable coverage everywhere else in the building.
Bi-Directional Amplifiers (BDA)
The bi-directional amplifier is the heart of the system. It receives the public safety signal and rebroadcasts it inside the building on the correct frequencies, and it carries radio traffic from inside the building back out to the network. We configure BDAs to the frequency bands your local agencies use.
Distributed Antenna Network
From the amplifier, a network of interior antennas connected by coax or fiber distributes coverage to every area that needs it. This is what carries the signal into stairwells, basements, elevators, parking levels, and the shielded interior spaces where radios normally fail.
Battery Backup and Code-Rated Enclosures
A public safety communication system has to keep working when the power does not. We provide standby battery backup sized to code and house the equipment in the survivable, fire-rated enclosures that ERCES standards require, so coverage holds during the emergency it exists for.
Fire Alarm Monitoring and Annunciation Integration
An ERCES is a supervised life safety system. We integrate it with a dedicated annunciator and tie its supervisory monitoring into the fire alarm system that meets your local code requirements so any fault, from antenna to battery, is reported the moment it happens.

Public Safety DAS Solutions for Every Industry in Topeka
Tech Electronics delivers emergency responder radio coverage tailored to the demands of each industry we serve. Building type drives everything, from where signals fail to which code applies.
Education
Schools and universities carry a growing set of public safety communication requirements, and the rules keep shifting. We design ERCES and in-building coverage for K-12 campuses and higher education, from classroom buildings and gymnasiums to dormitories and below-grade levels, so staff and responders stay connected during a lockdown or an emergency. With the University of Kansas in Lawrence and Kansas State University in Manhattan, our service area includes some of the state’s most prominent campuses.
Healthcare
Hospitals and clinics combine sprawling floor plates, below-grade imaging and mechanical spaces, and shielded rooms that are hostile to radio signals. We deliver public safety coverage that reaches these areas and coordinates cleanly with the facility’s fire alarm and other life safety systems. Tech Electronics upgraded the fire alarm systems in the clinical buildings of Stormont Vail Health, the region’s largest healthcare system, so we understand how hospital life safety systems need to work together.
Commercial
Office towers, mixed-use developments, and multi-tenant properties frequently trigger ERCES requirements through their size, their below-grade parking, or their construction materials. We design coverage that satisfies the code official and adapts as tenants and floor layouts change. Topeka’s state government, insurance, and financial services sectors occupy many of the larger office and civic buildings where a coverage survey is the first step.
Industrial
Warehouses, distribution centers, and manufacturing plants present some of the toughest radio environments there are: large volumes, steel and concrete, racking, and below-grade or interior spaces. As warehouse fire and life safety codes continue to tighten, in-building responder coverage is increasingly part of the conversation, and we design systems built for that scale. Northeast Kansas’s manufacturing and food processing sectors make this increasingly relevant for facilities throughout the region.
Life Safety
Facilities that support emergency response and public gathering, from municipal buildings to stadiums and event spaces, depend on flawless first responder communication. We design and maintain the coverage that keeps radios working where crowds gather and where command decisions are made.
Public Safety DAS System Types: Finding the Right Solution
The right system depends on your building’s size, its construction, the coverage the survey reveals, and the code that applies. Tech Electronics designs across several configurations.
Off-Air Signal Booster (BDA) Systems
The most common form of ERCES. A donor antenna feeds a bi-directional amplifier that rebroadcasts the local public safety signal inside the building. Efficient and effective for many small and mid-sized facilities that simply need reliable coverage brought indoors.
Active Distributed Antenna Systems
For larger or more complex buildings, an active DAS uses fiber to carry signal to remote units deeper into the structure, holding performance across long distances and many floors where a single amplifier would not reach.
Passive and Hybrid DAS
For smaller footprints or targeted problem areas, a passive coax-based distribution, or a hybrid of active and passive, delivers the required coverage without more infrastructure than the building needs.
Integrated Public Safety and Cellular DAS
Some buildings need both first responder radio coverage and better cellular service for occupants. Where it makes sense, we plan public safety and cellular DAS so a single, well-designed infrastructure serves both.

Public Safety DAS Systems FAQ - Topeka
What is a Public Safety DAS, and what do ERCES, ERRCS, and BDA mean?
A Public Safety Distributed Antenna System amplifies and distributes public safety radio signals inside a building so first responders can communicate reliably during an emergency. The same system is referred to by several names, including ERCES (Emergency Responder Communication Enhancement System), ERRCS, and BDA (bi-directional amplifier) system. They all describe in-building emergency responder radio coverage.
How do I know if my Topeka building needs one?
The answer comes from a professional signal survey. A technician measures radio coverage on a grid throughout the building and compares it to the code requirement, generally 95 percent coverage in general areas and 99 percent in critical areas. If the building falls short, a Public Safety DAS is typically required for code compliance and occupancy.
Is Public Safety DAS required by code?
For many buildings, yes. In-building emergency responder radio coverage is addressed by the International Fire Code, the International Building Code, and NFPA standards, and it is enforced locally by your Authority Having Jurisdiction. Requirements vary by jurisdiction, so always confirm with your local AHJ. Our team designs to the specific code adopted where your building sits.
Does my building qualify even if it is not a high-rise?
Very possibly. Coverage requirements commonly apply to buildings over roughly 10,000 square feet and to structures with below-grade spaces such as basements and parking levels, regardless of height. Newer construction methods and energy-efficient materials can also block radio signals in ways that trigger a requirement. A survey is the way to know for certain.
Why isn't cell phone coverage enough for emergency communication?
Public safety radios and cell phones operate on different frequencies and different networks. A building can have decent cell service and still fail public safety radio coverage entirely. Emergency responders rely on their own radio systems, which is exactly what a Public Safety DAS is built to carry.
Does a Public Safety DAS require ongoing inspection and monitoring?
Yes. These systems require annual inspection and testing, and they must be supervised, with monitoring integrated into the building’s fire alarm system so any fault is detected and reported. We provide both the inspections and the monitoring as part of our support plans.
Which Northeast Kansas jurisdictions and AHJs do you work with?
Topeka, Shawnee County, Lawrence, Manhattan, and the surrounding communities each have their own Authority Having Jurisdiction and expectations for in-building coverage. Our Topeka team works with these authorities across Northeast Kansas, which helps keep design review and acceptance testing on schedule.
Do you handle design, installation, and AHJ acceptance testing across Northeast Kansas?
Yes. We deliver the full process: signal survey, system design, installation, final AHJ acceptance testing, and ongoing inspection and monitoring, for facilities in Shawnee County and surrounding areas including Lawrence, Manhattan, and communities throughout Douglas and Jefferson Counties.
