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.
