Advanced Axis AV-V70-KIT Instruções de instalação

These instructions cover the installation of the AV-V70-KIT (70Vrms Speaker Circuit Interface Card and Audio

Converter Transformer) to an Advanced AV-V70 universal audio converter.

Caution: Before installing, servicing or removing any printed circuit boards / transformers remove all

sources of power.

ATTENTION

OBSERVE PRECAUTIONS

FOR HANDLING

ELECTROSTATIC

SENSITIVE DEVICES

Installation (see figure 1):

[1] Carefully place the new Audio Converter Transformer (XFRM #2) over the studs above the existing/original AV-

V70 Audio Converter Transformer (XFRM #1). Place the provided washer and lock washer over each stud and

secure with the provided nuts.

[2] Remove the four screws securing the original AV-V70 70Vrms Speaker Circuit Interface Card and replace with

the provided four standoffs

[3] Secure the new 70Vrms Speaker Circuit Interface Card to the installed four standoffs with the four previously

removed screws.

[4] Wire the black wires, attached to the new Audio Converter Transformer (XFRM #2) to the Audio Transformer

25V terminals on the new 70Vrms Speaker Circuit Interface Card.

[5] Wire the red wires, attached to the new Audio Converter Transformer (XFRM #2) to the Audio Transformer 70V

terminals on the new 70Vrms Speaker Circuit Interface Card.

Trbl #2 LED Wiring (see figure 1):

[1] Connect the black end of the provided two pin cable assembly to the two pins labeled Remote LED

Connections Trouble, located on the new 70Vrms Speaker Circuit Interface Card. As this is not a keyed

connection, ensure the black wire of the two pin cable is installed on the K pin of the 70Vrms Speaker Circuit

Interface Card.

[2] Connect the other end (white) of the two pin cable to the Trbl #2 LED Drive connector on the LED Indicator

Card installed on the AV-V70 enclosure door, this is a keyed connection and can only be installed one way.

24VDC Wiring (see figure 1):

[1] Wire 24VDC regulated and power-limited power from the "Host" fire alarm control panel or from an ANSI/UL

Listed power supply, wiring should terminate on terminals 0V and +24V of the newly installed 70Vrms Speaker

Circuit Interface Card [0V = negative, +24V = positive].

[2] Wire from the newly installed 70Vrms Speaker Circuit Interface Card [0V = negative, +24V = positive] to the

bottom (original) 70Vrms Speaker Circuit Interface Card [0V = negative, +24V = positive].

"Host" Panel 25Vrms Speaker Circuit Wiring (see figure 2):

[1] Whether the "Host" speaker circuit is wired Class A or B, run the existing 25Vrms (40 Watt maximum) speaker

circuit wiring to the 25V Audio Input terminals B+ and B-, of the 70Vrms Speaker Circuit Interface Card. If the

"Host" speaker circuit is wired Class B, install the "Host" panel's speaker circuit end-of-line (EOL) resistor

across the 25V Audio Input terminals A- and A+ of the 70Vrms Speaker Circuit Interface Card.

[2] If the "Host" speaker circuit is wired Class A, instead of placing the "Host" panels speaker circuit end-of-line

(EOL) across the A- and A+ terminals, connect the return "Host" panel's Class A speaker circuit wiring to the

appropriate "Host" panel terminals.

This equipment is constructed with static sensitive components. Observe anti-static precautions

at all times when handling printed circuit boards. Wear an anti-static ground strap connected to

panel enclosure earth ground.
