The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to
constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.
WARNING (If applicable): The terminals marked with symbol of “ ” may be of sufficient magnitude to constitute a risk of electric shock. The external wiring connected to the terminals requires installation by an instructed person or the use of ready-made leads or cords.
WARNING: To prevent fire or shock hazard, do not expose this equipment to rain or moisture.
WARNING: An apparatus with Class I construction shall be connected to a mains socket-outlet with a protective earthing connection.

IMPORTANT SAFETY INSTRUCTIONS

Read these instructions.
Keep these instructions.
Heed all warnings.
Follow all instructions.
Do not use this apparatus near water.
Clean only with dry cloth.
Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
Do not defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
Protect the power cord from being walked on or pinched particularly at the plugs, convenience receptacles, and at the point where they exit from the apparatus.
Only use attachments/accessories specified by the manufacturer.
Unplug the apparatus during lightening sorts or when unused for long periods of time.
Refer all servicing to qualified personnel. Servicing is required when the apparatus has been damaged in any way, such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
Disconnecting from mains: Switching off the POWER switch all the functions and light indicators of the amplifier will be stopped, but fully disconnecting the device from mains is done unplugging the power cord from the mains input socket. For this reason, it always shall remain readily operable.
Equipment is connected to a socket-outlet with earthing connection by means of a power cord.
The marking information is located at the bottom of apparatus.
The apparatus shall not be exposed to dripping or splashing and that no objects filled with liquids, such as vases, shall be placed on apparatus.

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. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

WARNING: This product must not be discarded, under any circumstance, as unsorted urban waste. Take to the nearest electrical and electronic waste treatment center.
NEEC AUDIO BARCELONA, S.L. accepts no liability for any damage that may be caused to people, animal or objects due to failure to comply with the warnings above.

INTRODUCTION

ECLER IC6CLASS-54 is a low and high impedance 2-way loudspeaker which features a design in accordance with EN54-24 standard (Fire detection and fire alarm systems, Voice alarms – Loudspeakers), including a back can, ceramic connection terminals, thermal fuse and Internal FR wiring. It integrates a very careful and efficient selection of components (6″ woofer + 1″ tweeter), together with a mechanical design that provide a high-quality audio (“Hi- Fidelity” profile sound) and a very fast installation process, just using a basic set of tools.

MAIN CHARACTERISTICS:

EN54-24 certified
2-ways in-ceiling/in-wall loudspeaker
High impedance built-in transformer, allowing for 70V / 100V line applications (5 different power tappings available)
Low/high impedance power selection accessible from the front panel, once the loudspeaker is already installed in the ceiling
6″ Kevlar® woofer
1″ Silk dome (ACCW) tweeter
Aluminium front grill
Back can included
Ceramic connection terminals
Thermal fuse
Internal fireproof wiring
Available in white (RAL9003) finish
Fast installation procedure using a basic set of tools

LOCATION, ASSEMBLY AND CONNECTIONS

For proper product installation, circular holes have to be made in selected places and the appropriate wiring has to be prepared for each unit.
Here are the steps to follow for proper installation:

Make the mounting hole in the drop ceiling, after marking its outline with the supplied cutting template
Remove the connection box using a slight pressure on the back can of the speaker.
Pierce the rubber grommet of the connection box, passing the end of the speaker connection cable through.
Strip the two wires of the speaker cable end and connect them to a screw terminal inside the connection box, respecting the polarity between the speaker (IN + and -), the other speakers of the system and the amplifier feeding them. Note: there are two grommets and two connectors inside the connection box, connected in parallel to link another speaker if necessary.
Reinsert the connection box into the back can of the speaker.
Insert the speaker’s frame into the hole, taking care that the 3 revolving fasteners remain in the retracted position
Tighten each of the 3 screws accessible from the front of the unit. The revolving fasteners rotate and at the end of the tightening, the frame is fixed at its final position
Using a flat screwdriver, set one of the following taps with the power selector on the front of the speaker:
Tap #1| 12Ω – 30W
---|---
| Connection to a 70V line| Connection to a 100V line
Tap #2| 1,5 W| 3 W
Tap #3| 3,7 W| 7,5 W
Tap #4| 7,5 W| 15 W
Tap #5| 10 W| 20 W
Tap #6| 15 W| 30 W
Test the operation by powering up the sound system.
Finally, install the grill on the speaker frame and turn it slightly so that the revolving fasteners of the frame and the grille are fitted together. During assembly, hold the grate by the edges (not the perforated, centre part) to avoid damaging it. The installation must guarantee compliance with section 5.18 (IP21C) of the EN54 standard: 24.
NOTE: impedance and power values indicated are exposed according the EN54 standard. However, IC6CLASS-54 can be considered as a 16 Ω and 75WRMS loudspeaker in use when connected to low impedance lines.

PAINT

IC6CLASS-54 is ready to be painted and thus can match any cosmetic criteria of the environment in which it is installed.
Once the installation is complete, the front grill is the only visible part of the unit, simply paint it to get the desired result. Paint it carefully, avoiding excess paint from clogging the small holes in its central area.
