Reliable emergency responder radio coverage for Duarte buildings.
A Distributed Antenna System that boosts first-responder radio signal through steel, concrete, and below-grade spaces in Duarte, engineered to meet local code.
Policed under contract by the Los Angeles County Sheriff’s Department, Temple Station
Duarte does not operate its own police department — law enforcement is provided under contract by the LA County Sheriff’s Temple Station.
Duarte’s residential neighborhoods along Huntington Drive sit close to our own service area, and we regularly work on projects for homes and small businesses throughout the city.
Emergency responder radio coverage in Duarte
Emergency responder communication systems exist so firefighters and police can use their radios inside your building. Concrete, steel, underground levels, and stairwells all block signal, and when radios fail inside a structure the people responding lose contact with each other.
Duarte enforces this through the fire department during plan review and again at final inspection. Buildings with foothill residential, medical campus facilities, and light industrial along the freeway are the ones most likely to need a system, and grid testing is what determines whether yours does. We test first rather than assuming.
If coverage falls short, the system amplifies and redistributes the public safety radio signal throughout the building, typically using a donor antenna, a bi-directional amplifier, and distributed antennas on the floors that need them. It also needs supervised battery backup and monitored fault reporting, both of which get checked at inspection.
For healthcare, research facilities, and small industrial in the area, foothill properties here sit near wildland interface zones, which makes early smoke detection worth pairing with any security work. We handle the grid testing, design, permitting, installation, and the annual testing that keeps the system compliant after the certificate of occupancy is issued.
Does Duarte require in-building emergency responder radio coverage for new construction?
Requirements for in-building public safety radio coverage vary by project and jurisdiction. We coordinate directly with local fire authorities on testing requirements during design.
What is an ERC or Public Safety DAS system?
It's a Distributed Antenna System that amplifies and distributes public-safety two-way radio signal throughout a building, so fire and police radios work reliably in stairwells, basements, and other areas where steel and concrete construction would otherwise block the signal.
Does an ERC system in Duarte need to be tested after installation?
Yes, most jurisdictions require annual testing and recertification, with documentation kept on file for fire inspections. We handle ongoing testing and certification for our Duarte clients.
How do I know whether my Duarte building needs an ERC system?
Grid testing determines it. We test radio signal strength throughout the building against the required threshold, and if coverage passes, you do not need a system. Testing first is cheaper than assuming either way.
Does an ERC system in Duarte need annual testing?
Yes. These systems require periodic testing to stay compliant, and the results are typically requested at inspection. We handle the annual testing along with the original installation.
