Where other ERCES solutions require integrators to purchase different elements from a variety of vendors to create a complete solution, CEL-FI QUATRA RED simplifies the deployment by offering an all-in-one solution. It includes everything from the head end (Network Unit or NU), remotes (Coverage Unit or CU), Master Battery Back-up Unit (MBBU), Remote Annunciator, Emergency Power-off Switch (EPO), coverage measuring tools and comprehensive remote management. All components were built around the International Fire Code (IFC) and National Fire Protection Association (NFPA) standards, are NEMA 4X rated, listed to UL2524, and optimized as an integrated solution.
The CEL-FI QUATRA product family uses proprietary CEL-FI smart booster technology that is approved for use by more than 200 carriers around the world. When QUATRA RED is installed, the technology intelligently delivers the same strong signal to all emergency responders inside the facility regardless of where they are located in relation to the system head-end or macro high site.
The system also simplifies the testing process, ensuring it passes the inspection done by the Authority Having Jurisdiction (AHJ). CEL-FI QUATRA RED is the first ERCES solution that includes built-in uplink grid testing along with downlink grid testing. The CEL-FI Compass handheld receiver tool is used to record the measurements on a 20- or 40-grid and input the data into the CEL-FI WAVE PRO cloud-based management system that produces a formal report for the AHJ’s Certificate of Occupancy or annual fire safety inspections. Using the testing tools can save considerable costs, and it speeds up the certification process by eliminating the need for the AHJ to return multiple times to redo tests.
A single CEL-FI QUATRA RED system will cover up to 1,200,000 sq ft, and multiple systems may be combined for even larger projects. Powernet installed one Network Unit (NU) which is the head-end of the system, in each building. With the exception of the remote antennas, all head-end system components were installed in the ground floor stairwell areas, which are fire rated, in each building.
The Monitor & Battery Backup Unit (MBBU) provides constant direct current, alarming, monitoring, and battery charging capabilities. It integrates a wireless LTE modem and a wired Ethernet port for remote access to all the CEL-FI QUATRA RED components via the CEL-FI WAVE Portal or the WAVE PRO app.
The CEL-FI QUATRA RED Remote Annunciator Panel provides automatic supervisory signals for any malfunctions of the ERCES system. Designed to prevent inadvertent operation, the QUATRA RED Emergency Power-off Switch can instantaneously shut down the ERCES solution from a single point to eliminate the risk of combustion caused by electricity or static.
Powernet installed a total of 4 Coverage Units (CUs) connected to service antennas in the 600,000 square foot building, and 3 CUs in the 200,000 square foot building. Paige GameChanger Ethernet cable was used to deliver lossless signals from the NUs to the CUs utilizing Power over Ethernet (PoE). The PoE architecture allowed for a quick installation and alarm configuration. Powernet installed a single donor antenna on the roof of each building to receive the Land Mobile Radio (LMR) signal from the closest high site.
“The tools included with CEL-FI QUATRA RED made the installation quick and painless,” says Morales.
digital and uses lossless Ethernet cabling, making the installation easier and faster. Power over Ethernet eliminates the need to install additional power outlets for the Coverage Units (aka Remote Units).
Issues frequently arise when public safety and commercial cellular amplification solutions are installed in the same facility due to interference between the signals of the systems. This problem usually needs to be resolved by placing large cavity filters between the head-end of the two systems and the remote units. These filters cost between $1,000 to $2,000 and many would be needed in facilities as large as these.
However, when CEL-FI QUATRA RED and CEL-FI QUATRA 4000 are installed in the same facilities to address both public safety and commercial cellular coverage, this problem is avoided. CEL-FI products are guaranteed unconditionally network safe, with no interference on the macro or other networks.
CEL-FI QUATRA has a Network Unit (NU) that is the head-end of the system, and Coverage Units (CUs) that are the remote RF units to connect external antennas and distribute the cellular signal throughout the buildings. Powernet installed three NUs and 15 CUs in the 600,000 square foot building, and one NU and five CUs in the 200,000 square foot building.
Two donor antennas for the cellular carriers were installed on the roof of each building. One donor antenna on each building was dedicated to Verizon, with the remaining three major carriers consolidated on the other antenna. In compliance with IFC and NFPA codes, separate donor antennas were installed for the CEL-FI QUATRA and CEL-FI QUATRA RED systems. The cabling was wired separately for each system as well.
