Frequently Asked Questions - NQ-S181CT-G2 Bogen

How do I install the NQ-S181CT-G2 ceiling speaker?

Remove the ceiling tile, center the TB8 tile bridge on the back, trace and cut an 8.5-inch square hole. Attach the speaker to the tile bridge using the supplied screws. If using the optional RE84 recessed enclosure, bend up the tabs on the TB8. Finally, place the tile back into the ceiling grid.

What power source does the speaker require?

The speaker is powered via Power over Ethernet (PoE) using an IEEE 802.3af compliant network switch or PoE injector. Connect using a Cat5 or higher Ethernet cable.

How do I reset the speaker?

Press the Reset button on the speaker. A short press reboots the device; a longer press resets configuration settings to factory defaults. Refer to the configuration manual for details.

Can I use the speaker without PoE?

No, the speaker requires PoE for both power and data. It does not have an alternative power input.

What is the CAN Bus interface used for?

The CAN Bus allows connection of NQ-E7020 Digital Call Switches to the speaker. Use twisted pair cable for CAN_H and CAN_L.

How do I connect an external device to the relay output?

The dry contact relay has NO (Normally Open) and NC (Normally Closed) terminals with a common COM. Connect your device accordingly for normally open or normally closed operation.

What is the warranty period?

The speaker is warranted for 5 years from the date of sale to the original purchaser against defects in materials and workmanship. See the warranty section for full terms.

How do I configure the speaker?

The speaker supports DHCP for automatic discovery and configuration by a Nyquist server. Alternatively, access the web-based user interface for manual configuration including DSP settings and firmware updates.

What optional accessories are available?

Optional accessories include the RE84 Recessed Enclosure, TB8 Tile Bridge, MR8 Mounting Ring, and NQ-E7020 Digital Call Switch.

Is the speaker suitable for residential use?

This device is FCC Class A rated for commercial environments. In residential areas, it may cause harmful interference; the user must correct interference at their own expense.

Nyquist Gen-2 VoIP Ceiling Speaker Installation Manual

With the Nyquist Series Gen-2 VoIP Ceiling Speaker, there is no need for external amplifiers, traditional intercom wiring, or transformer taps to manually set or adjust. Connect the speaker via Cat5 to a Power-Over-Ethernet (PoE) Switch or PoE Injector, and it is ready to use.

The speaker features an integrated 10 watt power amplifier, a CAN Bus interface, a MEMS digital microphone for superior talkback audio, and a Form C SPDT type 2-amp dry contact relay for controlling/overriding third-party devices like AV sources.

The speaker also allows DHCP deployment for easy installation. You can let your Nyquist server automatically discover and configure your speaker, or you can manually configure it through the speaker's web-based user interface (web UI). The web UI also allows easy updating of firmware and setting of parameters for Digital Signal Processing (DSP). For more information about the web UI, refer to the Nyquist Gen-2 VoIP Speakers Configuration Manual.

The layout of the speakers should be planned before installation begins. Layout starts in one corner of the room. The first speaker should be positioned from each wall spaced a distance approximately equal to the ceiling height of the room.

The next speaker in Row 1 should be spaced a distance approximately equal to twice the height of the ceiling. Each additional speaker in the row should use this same spacing.

Row 2 starts at twice the ceiling height distance from row 1 and twice the ceiling height from the wall. The other speakers in this row are also spaced at twice the ceiling height.

Row 3 is again spaced at twice the ceiling height from the previous row. The first speaker starting this row is positioned at one ceiling height distance from the wall (similar to row 1).

Continue this pattern of alternating rows until the room is covered. The spacing of the speakers can be adjusted so that the speakers are evenly spaced in a row and are aesthetically pleasing.

Mounting Equipment/Accessories

RE84 Recessed Enclosure

The RE84 is an optional back box for ceiling speakers. UL Listed for use where ceiling plenum is part of an air handling system, the RE84 also includes attachment tabs allowing the enclosure to be supported from structures other than the actual ceiling grid.

TB8 Tile Bridge

The TB8 supports the weight of the speaker and recessed enclosure. This is also the item to which the speaker mounting screws attach. The TB8 is required for each speaker assembly installed.

MR8 Mounting Ring

The MR8 Mounting Ring is a cold-rolled steel unit, which will mount any of the Bogen ceiling grilles, for installations where the RE84 is not used.

Speaker Installation

1. Remove the tile from ceiling and center the TB8 tile bridge on the back. Use the tile bridge to trace out, and then cut an 8-1/2" square hole. NOTE: It can be more efficient to stack multiple ceiling tiles and then cut the speaker opening in a number of them at one time.

1. If using the optional RE84 Recessed Enclosure, bend up the four (4) horseshoe tabs (Figure 1) on the TB8.

Speaker Installation (cont'd)

1. Position the TB8 over the hole in the tile and push down the locator tabs (Figure 2).
2. Using the 4 supplied screws, attach the speaker to the TB8 Tile Bridge using the 4 clips in the corners of the opening on the TB8 as nuts.

NOTE: Only tighten the screws until the grille is snug against the tile. Over tightening will cause screws to dimple the grille.

1. When applicable, use the pluggable CAN bus connector to attach one or more NQ-E7020 Digital Call Switches to the Nyquist VoIP Form C Module 820-00071-00 as shown in Figure 3.

1. If the CAN Bus is to be used, ensure CAN_H and CAN_L use (Cat5 10/100) twisted pair cable.
2. To connect a third-party device to the dry contact relay output, do one of the following:

a. If the device is looking for a Normally Open contact, connect the device using the NO and COM terminals.
b. If the device is looking for a Normally Closed contact, connect the device using the NC and COM terminals.

Speaker Installation (cont'd)

1. Make the electrical connections using Category 5 or higher Ethernet cable with an RJ-45 connector (Figure 4). The power is supplied by PoE using an 802.3af compliant network switch or PoE injector.

2. Place the entire assembled ceiling tile back into the ceiling grid.

NOTE: Refer to the Nyquist Gen-2 VoIP Speakers Configuration Manual or the System Administrator Manual for detailed instructions on how to configure these speakers.

Using the Reset Button

The Reset button (Figure 5) allows you to either reboot the VoIP speaker or to reset the appliance's configuration settings to the factory default settings. For more information about resetting configuration settings, refer to the Nyquist Gen-2 VoIP Speakers Configuration Manual.

Additional Accessories

The Nyquist Gen 2 VoIP Ceiling Speaker can be used with the Nyquist Digital Call Switch NQ-E7020. Refer to the Nyquist Digital Call Switch NQ-E7020 Quick Start Guide.

NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules.
