6 FAQs about [EMS for installing communication base stations on rooftops]

What is an in-building emergency responder Communications Enhancement System (Erces)?

An In-Building Emergency Responder Communications Enhancement System (ERCES) is a wireless communications system used by first responder and emergency services personnel, such as police, fire, emergency medical, homeland security, and disaster response agencies.

What are the components of an emergency responder Communications Enhancement System?

The components of an emergency responder communications enhancement system include: Donor antenna: This typically sits on the rooftop of the building and is the bridge between the radio tower network and the in-building communications enhancement system.

What are the NFPA requirements for emergency responder Communications Enhancement Systems?

In the 2024 edition of NFPA 101 ®, Life Safety Code®, requirements for emergency responder communications enhancement systems are found in Section 9.15. New buildings are required to comply with NFPA 1225, while for existing buildings the minimum required signal strength is determined by the authority having jurisdiction (AHJ).

Do rooftop antennas cause RF emissions?

When cellular and PCS antennas are mounted on rooftops, RF emissions could exceed higher than desirable guideline levels on the rooftop itself, even though rooftop antennas usually operate at lower power levels than free-standing power antennas. Such levels might become an issue for maintenance or other personnel working on the rooftop.

Should firefighters be aware of roof-mounted transmission devices?
