Installation Instructions
Product Summary
The ITI® Voice Siren 25/70 Volt Converter Card adds high voltage
voice siren audio output capability to Advent panels. The converter card is only for use
with the tone generator output. It is not listed for
use in voice evacuation. The card mounts
inside the panel enclosure and is powered by the panel voice siren output. The card
converts the panel 4-ohm voice supervised siren output to a 25 or 70 volt, 24 watt
supervised output. All circuits associated with this card are power limited.

Installation Guidelines
Advent systems support one
card per panel. Do not exceed the panel voice siren output power (see panel Installation
Instructions). The Voice Siren Converter Card must
have a minimum load of 1 watt and a maximum of 24 watts.
Tools and Supplies Needed
Small and medium blade
screwdrivers. #6x1/4 -inch self-tapping phillips pan head screws (included). R 2K ohm 5 watt
end-of-line (EOL) resistor assembly (49-482) (included with card). 14-gauge or larger
solid wire. Use larger gauge wire for long wire runs.
Do not use the 3 watt end-of-line resistors that are included with Advent panels.
Installation
The card is mounted inside the panel enclosure. To prevent damaging the panel or card, remove panel AC power and disconnect
backup battery before installation. You must be free of all static electricity when
handling electronic components. Wear a grounding strap or touch a bare metal surface
before handling circuit boards.
Mounting the Card
1. Remove panel AC power and disconnect the panel backup battery.
2. Place the card inside the cabinet below the panel circuit board (Figure
2).
