Reliable emergency responder radio coverage for San Marino buildings.
A Distributed Antenna System that boosts first-responder radio signal through steel, concrete, and below-grade spaces in San Marino, engineered to meet local code.
Policed by the San Marino Police Department
San Marino maintains its own small police department, so permits, response, and dispatch all run through the San Marino Police Department rather than a larger regional agency.
San Marino’s historic estates and quiet residential streets call for a discreet approach that protects the property without disrupting its architecture or landscaping. Because we’re based just minutes away in Alhambra, San Marino jobs typically get same-day availability and the fastest turnaround of anywhere we service.
Emergency responder radio coverage in San Marino
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.
San Marino enforces this through the fire department during plan review and again at final inspection. Buildings with large-lot estate homes on mature tree-lined streets, with minimal commercial 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 almost entirely high-value residential in the area, homeowners here consistently prioritize keeping equipment visually unobtrusive, which shapes both device selection and cable routing. 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 San Marino 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 San Marino 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 San Marino clients.
How do I know whether my San Marino 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 San Marino 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.
