02. INTRODUCTION

During an emergency incident, every minute is critical. First responders need to be able to communicate with each other inside and outside of any structure at any time. Nextivity's SHIELD EXTEND Public Safety solutions are designed to provide complete-code compliant radio coverage to higher performance standards in less time.

This guide also refers to additional tools and resources, such as the WAVE Portal, WAVE PRO app, and the COMPASS device. This guide only explains their usage as they pertain to SHIELD EXTEND. For more information on how your business may benefit from these resources, please refer to the product page.

 

 

 

System Overview

SHIELD EXTEND consists of a Network Unit (NU) and up to six (6) Coverage Units (per NU). The Network Unit takes off-air signals from separate LMR and FirstNet donor antennas, and digitizes the RF signals for distribution to up to six Coverage Units (CU) over dedicated Category (Cat5e or better) cables. CUs convert the digital signals back to RF, and boosts them for retransmission through local service antennas. The system also automates many traditional install complications, helping to ensure faster system deployment and certification.

 

 

SHIELD EXTEND Components

SHIELD EXTEND is a modular solution with the following components:

• Network Unit (NU)
• Coverage Units (CU)
• Management Unit (MU)
• Battery Backup Unit (BBU)
• LPDA-R (resistive sense monitored donor antenna)
• WAVE Portal (cloud based monitoring and diagnostics)
• WAVE PRO mobile app (iOS or Android local GUI)
• Optional: Remote Annunciator panel (RA)
• Optional: Emergency Power-Off switch (EPO)
• Optional: RED Active Service Antennas (AA)
• SHIELD EXTEND Fiber Range Extender (FRE)
• Tools: COMPASS (works with the WAVE PRO mobile app)

Nextivity recommends the use of Category cable (CAT5e or superior) for data transmission and to provide electrical power (Power-over-Ethernet) to all the components in the system except were indicated in this user manual.

NU and CUs must be the same model and band configuration. SHIELD EXTEND provides a sophisticated network-safe design that has been engineered to minimize the embedded effects of signal amplification.

Use the following BBU backup power capacity chart to determine which BBU model and battery Amp-Hour (Ah) capacity is appropriate for your system to meet local authority backup power requirements.

Total capacity depends on the number of CUs connected to the NU, the SHIELD EXTEND model, and whether 12 or 24 hour backup power is needed.

 

NOTE - 1: For more information about battery charging and capacity, please see F – Power Circuits.

 

 

 

Fiber QRE Battery Sizing Adjustment Example

An LMR + FirstNet LTE system with three CUs that needs to run with 12 hours of battery backup requires four 80 AH batteries (see the table below). If one or two of the CUs will run off of a single Fiber Range Extender system (NU and CU side components), 18 AH must be added for a total of 80 + 18 = 98 AH, which rounds up to four 100 AH batteries for this example.

04. DONOR AND SERVICE ANTENNAS

 

Install, Cable and Aim the Donor Antennas

The Network Unit has two independent donor antenna ports for LMR and LTE services. Each of these ports is labeled and they are not interchangeable. The RF connector labeled "LMR" must be connected to the antenna pointing towards the LMR base station. The LMR port can receive both 700 and 800 MHz public safety signals. The RF connection labeled "CELL" must be connected to the antenna pointing towards the "LTE/Cellular" base station that supports FirstNet services. The RF connections must be made using cables with an impedance of 50 ohms. Do not over-tighten or over stress the N connector ports or damage may result.

Notes:

• DC Passing Lightning Arrestors must be used.
• Nextivity “-R” donor antennas incorporate a 10k ohm resistor for monitoring purposes. Alternatively, the installer may choose to use another donor antenna provided they also install a Nextivity C21-200-100 Antenna Resistor Adapter to the antenna feed.

 

 

 

Service Antennas

Coverage Units install in 2 Hour fire rated spaces and are coaxially cabled to service antennas throughout the areas to be covered. Details about service antenna installation and cabling go beyond the scope of this document.

Note: To use the built-in Uplink Grid Test feature with the WAVE PRO app, the operating frequencies of the service antennas must include FRS Channel 20 (462.375 MHz).

 

 

 

 

 

---

 

05. CABLING

This section applies to the cabling of all components of the SHIELD EXTEND solution. All cable and conduit terminations must use liquid-tight connectors. 

 

 

 

Ethernet Cable Connections

All Ethernet cables, shown in blue on the wiring diagram above, must be connected using the supplied liquid-tight connectors as indicated in this section.

Note: Only the WAN/LAN and RA cables use standard Ethernet protocols. All other Ethernet cables use proprietary signaling and will not work through active Ethernet equipment such as routers and switches.

Use CAT5e or better cable (24 AWG minimum). Once the Ethernet cables are connected, follow the instructions below to waterproof the connections at either end of each cable.

1. Pass the cable thru the screw-on cap
2. Insert the cable into the split sleeve and washers
3. Push the screw-on cap and washers in the receptacle
4. Apply on the screw-on cap a maximum mating torque of 4.1 - 6.1 in-lbs.

 

 

 

Network Unit Cabling (NU):

• NU – MU (Management Unit) Ethernet cable
• NU – CU1 Ethernet port cable to CU1
• NU – CU2 Ethernet port cable to CU2, and so on up to a maximum of six (6) CUs.

Optional RA and WAN/LAN Ethernet Cabling

• Connect the WAN/LAN port on the MU to a suitable WAN/LAN internet source. NOTE: While an internet connection is not mandatory for the system to operate, it is critical for system management, diagnostics, software updates and UL Grid testing.
• Remote Annunciator - Ethernet cable between the MU and RA.

Optional EPO Switch Cabling

The optional EPO switch also uses an Ethernet cable to connect it to the MU, but the EPO switch does not use Ethernet signaling. It is merely a wired relay connection. For the EPO switch end of the EPO cable, use a standard RJ45 connector and liquid-tight connector using the supplied RJ45 liquid-tight connector assembly as illustrated in the previous section.

For the MU end of the EPO cable, hardwire the cable to the EPO terminal block inside the MU as instructed below (this allows the use of 3rd party EPO or Knox switches, and the EPO OUT cable hole supports ½ inch conduit if desired):

 

 

 

1. The EPO cable enters the MU housing and is secured with the supplied liquid-tight gland shown below.
2. Locate and remove the “EPO” cable port plug on the top of the MU housing.
3. Insert the threaded gland barrel into the housing hole from the outside of the MU housing, and secure it internally with the locknut. The Pressure Fingers should be outside the housing.
4. Slide the Pressure Dome and Sealing Sleeve onto the cable, and feed the cable into the housing through the barrel about 12 inches.
5. Slide the Sealing Sleeve into the Pressure Fingers and secure with the Pressure Dome nut.
6. The barrel nut and Pressure Dome should be snug and the cable should not move. Do not over-tighten.

 

1. Inside the MU, route the EPO cable through a cable clamp to the EPO Terminal Block.
2. Strip ½ inch of wire insulation from wires 7 and 8 (the brown and brown/white Ethernet wire pair) and screw securely into the two small terminal block ports in either order.
3. The unused cable wires should be cut back to the cable jacket and may be protected with electrical tape. They are unused and not connected on the EPO Switch end of the cable.

 

DC Power and BBU Alarm Wiring

Use ½-inch liquid-tight conduit to connect the 48 VDC terminal block in the BBU to the 48 VDC terminal clock in the MU as shown below, and in Appendix B.

 

In this same DC conduit, also route and connect the Loss of AC Power, Battery Charger Failure and DC out OK alarm wires between the BBU and MU. All six wires must be connected.

 

 

 

 

Fire Alarm Control Panel Cabling

The included Form-C 24-pin cable may be used with the RA or the MU to send alarm signals to the building Fire Alarm Control Panel.

 

The cable has three pins per alarm: Normally Closed signal, Common Signal, and Normal-Open signal. Choose the appropriate signal according to the type of fire alarm control panel in the building.

 

 

 

1. When not using an RA, connect the Form-C cable from the ALARMS port on the MU directly to the Fire Alarm Control Panel.
2. When using a Remote Annunciator, connect an Ethernet cable between the MASTER port on the RA and the RA port on the MU, using liquid-tight RJ45 inline connectors, and then connect the Form-C cable from the ALARMS port on the RA to the Fire Alarm Control Panel.
3. Choose the appropriate pins (normal-open / common / normal-close) to set up the alarms in the main fire alarm control panel.

 

 

 

 

MU and NU Power Connections

NU Power Cable:

 

The NU is supplied with DC power using the liquid-tight NU power cable that is supplied with the MU. Attach the liquid-tight cable at either end by inserting it fully into the indicated ports on the wiring diagram and twisting the connectors to lock them in place.

 

 

NOTE: The twist-lock connectors are designed with one round tab and one squared groove to help prevent improper insertion and polarity. Observe the locking tabs and do not force the connectors on improperly.

 

 

 

BBU AC Power Requirements:

All external circuits intended to be connected to non power-limited wire shall contain either current-limiting or overcurrent protection to prevent fault currents in excess of the current rating for the gauge wire size permitted by the National Electrical Code, ANSI/NFPA 70, or as specified in the installation wiring diagram/instructions.

 

BBU Main Supply Circuit:

AC power is supplied to the BBU AC port on the top of the BBU through ½-inch liquid-tight electrical metal conduit and cabling (not included) as described in Appendix B. The other end of the AC power cable must be connected to an electrical junction box, and the 3-wires terminated to the AC supply branch circuit inside the junction box.

Appendix G - Preventative Maintenance

BBU Main Batteries and Charging

Nextivity recommends Deep-Cycle batteries (inspect and maintain BBU batteries according to battery manufacturer instructions).

 

Normal Battery Voltage	48VDC
Charge Voltage	52-56VDC
Current (Max)	11A

 

Once a year, inspect the BBU batteries for cracks or corrosion, and make sure wires and battery connections are not loose or corroded. Clean and tighten battery terminals if needed.

If the BBU Low Battery Capacity LED alarm is triggered, perform the following tests:

Step 1: Open the BBU door panel and power down the BBU by switching OFF both DC and AC circuit breakers.

Step 2: Remove all battery wire terminals, being careful not to short any wires to the BBU housing. Inspect and clean battery terminals and wire connections. Measure the Open Circuit voltage of each battery. The volt meter negative tester lead must connect to the battery's negative post and the positive tester lead to the positive post.

Step 3: If your gel battery displays a charge within the 12.85 to 12.95 range, it is 100 percent charged. All batteries should measure within this range if freshly charged. A voltage of 12.65 means it is only 75 percent charged, while a 12.35 reading correlates to a 50 percent charge. A voltage reading of 10.5 volts or lower usually indicates a dead or damaged cell battery which must be replaced.

Step 4: If any battery fails to fully charge after the wire terminators and battery terminals have been cleaned and properly attached, replace the battery.

 

 

Remote Annunciator Internal Lithium Battery

The RA internal battery requires no maintenance and it not user replaceable.

 

 

Other System Components

The NU, CUs, EPO, and QRFRE do not require maintenance.

Appendix I - Optional Fiber Range Extender

Description of Operation

Some SHIELD EXTEND installations may require NU to CU cable lengths in excess of what Ethernet cable can accommodate (100m using Cat5e Ethernet cable). The SHIELD EXTEND Fiber Range Extender adds up to an additional 1400 meters of CU cable length, using optical fiber cable for data transmission and DC cable to transport BBU power.

The Fiber Range Extender is comprised of two units; one NU-FRE and one CU-FRE. The NU-FRE unit receives power from the MU and converts the Ethernet CU cable signals from the NU into optical cable signals. The NU-FRE then sends the data and power to the CU-FRE unit over the fiber/DC cable, where the CU-FRE converts the signals back to Ethernet plus power (PoE) to be received by the CUs. Each Fiber Range Extender kit can accommodate one or two CUs.

 

System Architecture when using QRFRE units

Normally, MU DC power is cabled directly to the NU through the NU Power Cable. When using FREs, power is first fed serially through up to three NU-QRFRE units using the same NU Power Cable assemblies as shown below. Each FRE system (one NU-FRE plus one CU-FRE) may support one or two CUs.

 

 

DC POWER CABLE LENGTH (max meters)	AWG (POWER CABLE WIRE GAUGE)
	12 AWG	11 AWG	10 AWG	9 AWG	8 AWG
Fiber RE connected to one CU	556m	701m	883m	1114m	1400m
Fiber RE connected to two CUs	280m	353m	445m	562m	708m

 

 

FRE Cabling

DC POWER from the MU to the FRE

Each NU-FRE comes with a DC Power Cable that is identical to the DC Power Cable supplied with an NU. Note that the cable has a male and female end and both ends maintain proper polarity by only allowing the connectors to be inserted with one orientation. Twist lock the connectors to complete the connections.

Power passes from the MU, through the NU-FRE(s), and finally to the NU.

 

 

CU Ethernet cables between the NU and NU-FRE

To connect the CU Ethernet cables from the NU to the FRE, unscrew the cable compression nut on the FRE housing and feed the cable(s) through the nut and rubber grommet and into the FRE where they connect to the internal FRE CU 1 port. Then slide the compression nut over the grommet and cable and tighten. If a second CU is to be connected, follow the same procedure to connect the CU2 cable between the NU and FRE.

 

The Fiber cables (to the NU/CU-QRFRE) are connected in the same manner.

 

NU and CU-FRE DC Connections

Each Fiber FRE kit includes two DC Jack pigtails (see the diagrams below). The two conductor, user supplied DC WIRE that transfers DC power from the NU-FRE to the CU-FRE is connected to these pigtails on either end using the supplied wire crimp splice connectors.
Then the pigtail connector is inserted into the FRE housing through the liquid-tight nut opening, and plugged into the DC port. Finally, tighten the liquid-tight nut to secure the DC cable.

 

 

CU Ethernet cables between the CU-FRE and the CU

To connect the CU Ethernet cables from the CU-FRE to a CU, unscrew the cable compression nut and feed the cable(s) through the nut and rubber grommet, and into the FRE where they connect to the internal FRE CU 1 port. Then slide the compression nut over the grommet and cable and tighten. If a second CU cable is to be connected, follow the same procedure to connect the CU2 cable between the CU-FRE and CU2.
