ERRCS solutions for safer buildings and reliable emergency communications.
TELNET tests, designs, installs, certifies, and monitors Emergency Responder Radio Coverage Systems, also known as in-building public safety communication systems.
When first responders enter a building, reliable voice and data communications can be mission-critical. TELNET helps property owners and project teams address coverage gaps and coordinate requirements with the local authority having jurisdiction.
Reliable communications when response time matters.
ERRCS projects require coordination between building owners, project teams, public safety stakeholders, and local code requirements.
- Coverage testing and gap analysis
- Public safety DAS design and support
- Inspection and certification readiness
From survey through ongoing support.
Coverage testing and survey
We evaluate current public safety radio coverage and identify areas that need improvement.
- Site survey
- Grid testing
- Coverage gap identification
- Pre-construction planning support
Public safety DAS implementation
TELNET can support the design, coordination, installation, and testing path for ERRCS systems.
- Public safety DAS design
- AHJ / OUC coordination
- Construction and installation support
- Third-party testing and certification support
Monitoring and repair
After deployment, ERRCS systems require ongoing attention so they remain ready when needed.
- Maintenance and repair
- Alarm monitoring
- Trouble ticket support
- System documentation and reporting
For general contractors, owners, and A&E teams.
TELNET brings RF engineering, AHJ coordination, field implementation, acceptance testing, commissioning, closeout documentation, and maintenance into one delivery path so coverage and code questions are addressed before they become late-project surprises.
Early code and coverage review
We help project teams identify ERRCS requirements, jurisdiction expectations, and coverage risks while drawings, budgets, and schedules can still be adjusted cleanly.
- AHJ and local requirement review
- Existing signal and site-condition planning
- Design assumptions for new construction or renovation
Coordination with the project team
Our team connects RF design with the realities of construction, including pathways, power, monitoring, equipment locations, and trade coordination.
- RF design and public safety DAS planning
- Coordination with GC, electrical, fire alarm, and low-voltage teams
- Field support for implementation questions
Testing and AHJ closeout support
We prepare the testing, documentation, and inspection support needed to help reduce rework and protect occupancy timelines.
- Grid testing and acceptance readiness
- Closeout documentation and reporting
- Inspection coordination and issue resolution support
Monitoring, maintenance, and changes
After occupancy, TELNET can help keep the ERRCS ready through monitoring, maintenance, repairs, and updates when building conditions change.
- Alarm monitoring and maintenance support
- Troubleshooting and repair response
- Retesting or modifications when needed
Designed around local requirements and practical safety outcomes.
ERRCS requirements vary by jurisdiction and project type. TELNET helps clients understand the practical path for surveys, design, documentation, inspection coordination, and system readiness.
- Support for new construction and existing facilities
- Coordination with project teams and local authorities
- Public safety DAS, BDA, repeater, and monitoring considerations
- Documentation for inspections and occupancy support
- Clear next steps for improvement plans
- DC OUC-approved vendor experience
