The SHIELD EXTEND Class A or Class B 700MHz/800MHz channelized Emergency Responder Radio Communications System (ERRCS) Smart Signal Booster was designed with the needs of First Responders, Building Owners, Installers, and Authorities Having Jurisdiction (AHJs) considered. The SHIELD EXTEND is a complete solution, each component fully-compliant with the current International Fire Code (IFC) and National Fire Protection Association (NFPA) standards.
As the public safety community evolves to include cellular LTE support, the SHIELD EXTEND is the only solution that offers true carrier-grade channelized support for FirstNet. Both LMR and LTE aggregated at the head-end, digitally-distributed over Category cable, and retransmitted through a single serving antenna or DAS field.
SHIELD EXTEND is the first and only solution in the market that can easily be scaled from a single donor “BDA” deployment at 1 or 2 watts to a full-blown (single donor) “Fiber DAS” up to 12 watts.
SHIELD EXTEND is best-in-class with 56 individually configurable channels (700MHz and 800MHz) and 1W downlink per Coverage Unit (CU) per band. Best-in-class channelized uplink squelch and channelized uplink automatic gain control (AGC), inherited from Nextivity’s carrier-grade LTE technology platform, unconditionally guarantees no interference to base stations and optimizes signal quality.
SHIELD EXTEND includes all standard alarms, supports all NFPA and IFC-required monitoring, and connects to Nextivity’s carrier-grade, SOC 2 (Type 1)-certified WAVE portal, providing best-in-class on-demand remote monitoring, not just for standard alarms but also to ensure system KPIs.
Where competing products require integrators to purchase pieces and parts from a variety of vendors to create a complete solution, the SHIELD EXTEND solution offers everything from the head end (Network Unit or NU), remotes (Coverage Unit or CU), Battery Back-up and Monitoring (MBBU), Remote Annunciator, Emergency Power-off Switch (EPO), and an As-Built Box. All NEMA 4X rated and optimized together.
SHIELD EXTEND Monitor & Battery Backup Unit
The Monitor and Battery Backup Unit (MBBU) is the central point of the CEL-FI SHIELD EXTEND system. It provides constant direct current, alarming, monitoring and battery charging capabilities. Integrates a wireless LTE modem and a wired Ethernet port for remote access to all the components via the CEL-FI WAVE Portal or the WAVE PRO app. Is NEMA 4 rated and UL2524 compliant. Two versions available to optimize power requirements and installation costs.
SHIELD EXTEND Remote Annunciator Panel
The SHIELD EXTEND Remote Annunciator Panel provides automatic supervisory signals for malfunctions of the ERRCS solution. Rated NEMA 4, it complies with Chapter 10 of NFPA 72 and section 9.6.13 of NFPA 1221. The PoE architecture allows for a quick installation and alarm configuration. The unit includes a FORM-C cable compatible with any fire alarm control panel (open or short circuits).
SHIELD EXTEND Emergency Power-off Switch
SHIELD EXTEND Emergency Power Off Switch (EPO) can instantaneously shut down the ERRCS solution from a single point to eliminate the risk of combustion caused by electricity or static. Designed to prevent inadvertent operation and can be installed in any location designated by the authority having jurisdiction.
SHIELD EXTEND Network Unit
The Network Unit (NU) processes FirstNet and LMR off-air signals digitally to provide reliable and interference-free coverage. PoE based architecture and CEL-FI patented algorithms for automatic setting of uplink and downlink gain, reduces time and cost of installation significantly, making SHIELD EXTEND the most compelling public safety solution in the market.
SHIELD EXTEND Coverage Unit
The Coverage Unit (CU) amplifies FirstNet and LMR signals up to 24 dBm and 30 dBm output power. The ease of installation plus the SelfOrganizing Edge Intelligence makes SHIELD EXTEND the most compelling solution in the market.
