Voice Siren 25/70 Volt Converter Card
Installation Instructions
Terminal strip Used for panel and voice siren connections.
Product summary
The Voice Siren 25/70 Volt Converter Card adds high voltage
voice siren audio output capability to Advent panels.
Note: 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 4ohm 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).
Note: 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).
• 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.
Caution: 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.
Caution: To prevent damaging the panel or card, remove
panel AC power and disconnect the backup battery before

Wiring the Card
This section describes how to wire the card to an Advent panel
and speakers.
Note : (A) Class 2, Class 3, and power-limited fire alarm
circuits must be installed using FPL, FPLR, FPLP, or substitute
cable permitted by the National Electrical Code ANSI/NFPA
70. Wire that extends beyond the cable jacket must be
separated from all other conductors by a minimum of 1/4-inch
or by a nonconductive barrier.
Or
(B) Class 2, Class 3, and power-limited fire alarm circuit
conductors must be installed as Class 1 or higher circuits.

Note: Separate in and out conductors must be used at each
speaker. Do not loop a single wire around each terminal.
Powering Up the Panel
This section describes how to power up the panel and the
card.
To power up the panel and card:
1. Verify that all wiring at the panel and the card is correct.
2. Reconnect the panel battery and restore panel AC power.
Testing
Refer to the specific panel’s Installation Instructions for testing
voice siren operation and supervision.
To wire the card:
1. If you have not already done so, remove panel AC power
and disconnect the panel backup battery.
