System availability (dependent on donor signal and power)
A BDA (Bi-Directional Amplifier) pulls public safety signal from a donor antenna mounted outside the building
That amplified RF signal is distributed entirely over coaxial cable
Passive components (splitters, taps, directional couplers) balance signal levels across the building
Each coax run feeds indoor antennas placed to meet coverage and code requirements
Our experts will assess your building and recommend the most cost-effective solution.
Your passive DAS must meet ALL requirements for AHJ approval
All Requirements Must Pass
Minimum -95 dBm signal strength in all general areas of the building
Stairwells, fire command center, pump rooms, exit corridors, elevator lobbies
All signal boosters must be listed specifically for in-building public safety
Cable routes protected by 2-hour rated enclosures or CI cable
Standby power for 24 hours quiescent + 5 minutes talk time
GFCI protected, on emergency power if available
System trouble and antenna malfunction alarms to fire panel
Recertification by qualified vendor every 12 months
Failure to meet ANY of these requirements will result in AHJ rejection. Our team ensures 100% compliance before installation begins, which is why we maintain a perfect AHJ approval rate.

Common questions about ERCES performance and scalability
Complete project timeline is 3-6 weeks: Site survey (1 day), Design and engineering (3-5 days), AHJ permit approval (1-2 weeks), Installation (3-5 days), Testing and commissioning (1-2 days), Final AHJ inspection (same day). Emergency fast-track available for buildings facing immediate compliance deadlines - we can complete in 10 days with expedited permitting.
No interference. Public safety DAS operates on dedicated emergency frequencies (VHF/UHF/700/800 MHz) completely separate from commercial cellular and WiFi bands. FCC Part 90 regulations require band-pass filtering to prevent any interference. Our systems include cavity filters and are tested for spurious emissions. Many buildings have both public safety and cellular DAS operating simultaneously without issues.
NFPA 1225 mandates annual testing and recertification ($2,500). Monthly visual inspections of equipment status indicators. Battery replacement every 3-5 years ($3,500). We offer comprehensive maintenance contracts including 24/7 monitoring, annual testing, emergency response, and all required documentation for $3,500-$5,000 annually. Remote monitoring can detect issues before they cause coverage problems.
This has never happened with our installations - we maintain a 100% AHJ approval rate. Our design process includes pre-approval coordination with your local AHJ. We test all systems before the official inspection to ensure compliance. If any issues were to arise, we would resolve them at no additional cost. Our designs are conservative to ensure we exceed minimum requirements by a comfortable margin.
Yes, our systems integrate with all major fire alarm control panels (FACP) including Simplex, Notifier, Edwards, Fire-Lite, and Honeywell. We provide supervised dry contact outputs for system trouble and antenna fault monitoring. Integration typically requires 2-4 additional zones on your FACP. We coordinate with your fire alarm contractor to ensure seamless integration without affecting existing certifications.
Our systems support all public safety bands: VHF (150-174 MHz), UHF (450-470 MHz), 700 MHz Public Safety (763-775/793-805 MHz), and 800 MHz (806-824/851-869 MHz). We determine the exact frequencies used by your local fire department during the site survey. Multi-band systems are available for jurisdictions using multiple radio bands. All equipment is FCC Part 90 certified for public safety use.
