DESCRIPTION

A51T is a compact, two-way, surface-mount loudspeaker system designed for constant-voltage or constant-impedance applications. It is equipped with a 127 mm (5”) woofer and a 1” dome tweeter, able to provide an excellent speech intelligibility with wide dispersion, together with a very good background music reproduction.

A51T features a transformer to operate on 100V and 70V constant voltage systems. In a sealed compartment on the rear panel, together with the rotary selector for power taps or impedance, it includes, in compliance with EN 54-24:2008, a ceramic terminal block and a thermal fuse and it is, therefore, suitable for the use in voice alarm systems.

The ABS cabinet is available in black (A51TB) or white (A51TW) color finishing, allowing the best décor matching in any environment.

The IP43C environment protection allows the A51T speaker to be installed both indoors and outdoors.

INSTALLATION INSTRUCTIONS

[1]Separate the bracket parts (B) and (D) removing the screw and the washers (A). Then mark on the wall the fixing points for the (B) part (you can refer to the wall drilling template (H)).

[2]Fix the bracket (B) to the wall choosing an appropriate fastening system for the wall type (no fastening system is provided with the product – C). For maximum safety, consider that the fastening has to hold 5 to 10 times the weight of A51T. Note that the slot holes can accept two 6mm screws or bolts (C).

[3]Assemble the bracket part (D) to the speaker using the (E) screws.

[4]Remove the rear cover (F) and insert the speaker line cables into the black rubber slots. We suggest to use a proper speaker cable with two insulated wires in a single jacket, with diameter between 6mm and 12mm.

[5]Connect the speaker line wires to the terminator block (H), taking care to follow the +/- polarity.

[6]Set the power to be delivered to the speaker using the rotary switch (I).

WARNING! When the speaker is used in a 100V system, take special care NOT to set the rotary switch in position 5 (N.C.). Failure to observe this warning may cause damage to the

product.

[7]Close the rear cover (F) and fix the speaker to the wall, combining the two bracket parts (B) and (D) with the proper screw and washers (A).

[8]Aim the speaker to the listening area to be covered, then tighten the screw (A).
