Check the 70 A fuse on rear of unit and verify there is a 48 VDC supply to it. Check the LED status on the power supplies.

Refer to the installation guide for the LED status chart. RED = low voltage output. Reseat or replace the card. LED dark means: check the 48 VDC input, check the rear fuse, check that yellow/green ground wire on rear is grounded, reseat card, replace card.

This indicates that no receiver is connected. Check wiring for open or polarity reversal.

The GEN1 FPS-900 is not hot-swappable. The GEN2 FPS-1350DC and FPS-3000AC are hot-swappable.

Yes. Both are hot-swappable but are not interchangeable between the GEN1 FDET-BC-1800 and the GEN2 FDET-BC-5400DC or AC transmitters.

The GEN1 transmitter is 1U and has two power supply cards in the left side of the unit. The GEN2 transmitters are 2U with the upper shelf holding a supervisory card (FSPV2) on the far left, and, on the lower shelf, space for four power supply modules (FPS-1350DC or FPS-3000AC).

All GEN1 FPC-900 and Gen2 FPC-1000 cards are hot-swappable.

They are positioned for a center-post rack system. Simply remove the brackets, turn them over, and reattach for front-mount rack.

This depends on the number of power supplies installed. For the 5400DC, one 50-amp breaker is required for each power supply, with up to a 200-amp breaker when all four power supplies are installed. The number of power supplies required is determined by the system design.

Pages 22-25 of the FUZE installation manual show the various LED status conditions and descriptions of faults. You can also log into the FSPV GUI to check the description of the fault.

No, you cannot. The design rules state that you may never bundle transmit pairs from multiple transmitter shelves. All transmit pairs in any cable need to be from the same shelf, and all transmit pairs to any receiver must be from one transmitter shelf.

All transmitters and receivers must have an earth ground.

We do not recommend specific cable brands. The manual calls out the minimum characteristics of the wire and AWG that must be used. The mutual capacitance is not to exceed 50pF/foot and the voltage rating is a minimum of 300 V. See page 27 of the installation manual and call JMA tech support at +1.888.201.6073 for assistance with selecting the proper AWG based on system design.

The FDER-FMK-K1 is organized into 3 parts and requires some light assembly into the cabinet. See Install Guide FDER-FMK-K1 supplied with the kit.

- Cable must carry manufacturer specification for a minimum of 300 VDC.
- Cable must carry manufacturer specification for conductor mutual capacitance per unit length of 50pF/foot (150pF/meter) max. Do not use cable that does not carry expressed specification for capacitance.
- Twisted pair cable is recommended and preferred over linear laid cable.
- For linear laid cable (not twisted pairs), the cable manufacturer color code/conductor order must be followed. This is to ensure that all DE pairs use adjacent/sequential conductors within the cable jacket.
- Do not use cable with individual shielded pairs.
- For all deployments that are outdoors, aerial, or underground:
- Cable must be shielded (one single shield enclosing all conductors, not individual shielded pairs). Shield must be tied to earth ground at all junction points.
- OVP (Over Voltage Protection) is required at the originating end and terminating end of each DE pair (at DE TX and at DE RX). Recommended OVP unit is Citel DS240S-350DC.
- All DE pairs within any DE cable jacket must originate from the same DE TX (cannot route DE pairs from multiple DE TX into a common cable jacket).
- Use 20 AWG stranded wire to connect from DE TX cards to junction point feeding long-run DE cable(s). See JMA FTB-x, FPC-TAIL-48.
- Permissible AWG size range for DE cables (TX junction point to RX junction point) is 18 AWG, 16 AWG, and 14 AWG. Consult JMA Tech Support before using other AWG.
- The choice of DE cable is important. Consult JMA Tech Support with any questions.

The FMK-2LL support TEKO remote units from 2-3 band to 4-6 band. These are gasket adapters that are applied to the bottom of the remote units for proper sealing to the FMK unit.

Operating temperature of the FMK is from -4° F to 113° F.

The FMK cabinets are IP66 rated.

The fiber connector type is SC/APC.

FTB-6, FTB-12, and FTB-24. Accommodation for 6,12, or 24 pair terminations.

A Windows-compatible PC with an Ethernet port is required to access the FSPV2 web interface.

No. The power must be off when removing or inserting the FSPV2 module.

Page 3 of the FSPV2 user manual contains the default pre-configured network settings.

The LED on the unit is not illuminated.

This means "base configuration." Each transmitter shelf ships with one power supply and the FSPV2 supervisory module installed for its base configuration. FPC-1000 cards and power supplies are added per system design.

We recommend a minimum of 2 DE pairs to any receiver, which is determined by system design with AWG, length of wire, and total current load required to determine how many DE pairs are needed.

Yes. Page 29 of the installation manual will recommend that you check all grounding, input power polarity, and DE output polarity, then energize the transmitter with DE pairs not connected. Verify that all LED activity on power supplies are green and transmitter cards have a blinking blue light and a green LED flash alternating with a red flash. Power down the transmitter shelf, connect all DE pairs to the transmitter cards, ensure all DE pairs to receivers are correct and all loads are connected and switched to "on." Then, energize the transmitter rack again and verify all transmitter cards show a flashing blue and steady green LED.

Each FPS-1350DC has 1350 W total power output and 3000 W on the FPS-3000AC units. Available power of each after loss is considered with respect to wire, receiver, and FPC-1000 card is 1200 for the DC type and 2700 for the AC type. For example, to be N+1 for on the FDET2-BC-5400DC, a max of 3600 watts drawn with a quantity of 4 FPS is required.

No. Per design rules, individually shielded conductors are not allowed. Twisted pair is recommended and if aerial, buried, or outdoors, it is recommended to use cable with a shield around all conductors (not individually shielded). OVP is to be used on each end of each DE pair with the shield grounded to earth ground at every termination point.

Approved cables are available from Tessco, Belden, and Genuine Cable (Electrowire).

No. Each DE pair from each FPC-1000 must terminate to one receiver channel

This receiver comes non pre-wired CH 1-2 power supply to one output and CH 3-4 to the other. JMA can provide a diagram on how to jumper the output to a single output, with CH 1-4 thus powering one output up to 1800 watts.

FPC-1000SR provides up to 3.25 A, 500 W max. with up to 2,400 ft of reach, with SR stands for standard reach and LR for Long reach. FPC-1000LR provides up to 3.25 A, 500 W max. with 2200 ft of reach and above. Use of SR or LR cards is determined by the system design.

Polarity of the DC input power must be verified before physically connecting the conductors. Place the positive lead of a voltmeter on the conductor that will go to the +48 V terminal on the FDET2 transmitter, and the negative lead of the voltmeter on the conductor that will go to the -48 V terminal. Confirm that the meter indicates a positive voltage between 39 V and 56 VDC. If the reading is negative or outside the correct voltage range, do not connect the input conductors until the issue is resolved.

For all deployments which are outdoor, aerial, or underground: cable must be shielded (one single shield enclosing all conductors, not individual shielded pairs). Shield must be tied to earth ground at all junction points.
OVP (Over Voltage Protection) is required at the originating end and terminating end of each DE pair (at DE TX and at DE RX). Recommended OVP unit is Citel DS240S-350DC.
