A code compliant ERCES, SHIELD EXTEND offers building owners the fastest pathway to receiving their certificate of occupancy (CoO). The system combines industry-leading ease of installation, performance, and scalability with unmatched remote system monitoring and management to ensure reliable LMR and FirstNet connectivity indoors.
SHIELD EXTEND revolutionizes what it takes to install an emergency responder communication enhancement system (ERCES), making it quicker and less costly than ever before. With its advanced automation features, businesses can get a system installed, receive Authorities Having Jurisdiction (AHJ) approval, attain their CoO, open their doors, and start making money faster than with any other solution.
Nextivity proprietary IntelliBoost software inside SHIELD public safety solutions enables them to automate system parameters that no other ERCES can do. By automatically calculating and setting system parameters, SHIELD EXTEND allows installers to deploy an ERCES faster and with more confidence it will pass the first AHJ inspection than with other solutions.
The management Unit (MU) is the central point of the system. In addition to accepting and distributing power from the SHIELD EXTEND Battery Backup Unit (BBU), the MU controls and monitors all system components, including the Network Unit (NU), Coverage Unit (CU), and accessory components. System performance analytics are available in the Nextivity WAVE Portal or WAVE PRO app.
With its two donor ports, the NU processes and digitizes the off-air LMR and FirstNet donor signals and distributes those signals to the CUs. Each NU can support and power up to six CUs via PoE.
Model Number (Class A): F42-67ENU
Model Number (Class B): F42-67ENUB
The CUs rebroadcast LMR and FirstNet donor signals to local service antennas throughout the facility. They are self-configuring and self-optimizing, enabling faster system deployment and certification.
Model Number (Class A): F41-8XCU
Model Number (Class B): F41-8XCUB
The Battery Backup Unit (BBU) provides constant direct current and battery charging capabilities for SHIELD EXTEND systems. In the event of a power failure, the BBU allows SHIELD EXTEND to maintain peak operation for up to 12 hours. In addition to being NEMA 4 rated and listed to UL 2524, the BBU supports four 12-volt lead-acid batteries and includes accessories for wall mounting and cabling for connecting to the MU.
Ideal for campuses, multi-building facilities, and high-rises, the SHIELD EXTEND Fiber Range Extenders (FRE) increase the distance between the SHIELD EXTEND NU and CU up to nearly one mile. In addition to supporting copper cable to power up CUs remotely, FREs work in pairs and are sold as a kit that includes two units—one NU side and one CU side—with each pair supporting up to two CUs.
NU Side: F40-0XNU
CU Side: F40-0XCU
The SHIELD EXTEND integrated public safety DAS sets a new standard for performance, ease of installation, and scalability for emergency communication systems. In addition to delivering reliable in-building 700/800 MHz LMR and FirstNet coverage that keeps first responders and emergency personnel connected, this code compliant solution features PoE architecture and fiber expansion capabilities to support structures the largest structures. The system also offers advanced software capabilities – from Nextivity proprietary IntelliBoost technology – that allows SHIELD EXTEND to automate system settings and parameters without expensive or hard-to-use testing tools. This streamlined process speeds up installation times, allowing buildings owners to get their systems approved by AHJs and receive their CoO as fast as possible.
