Introduction to the Expansion Signal Card

Overview

The Expansion Signal (XSIG) Card provides three additional notification appliance circuits (NACs) for use with either an amplifier audio NAC or a power

supply card NAC (SPS, RPS, XPS). It is not compatible with the ES-PS simple NAC or NAC Cards. When you add an XSIG Card for audio NAC expansion,

program the card for operation with the specific amplifier that it is expanding.

Each XSIG card must be dedicated to provide either all Audio or all DC notification; these operations cannot be mixed.

Functions of the XSIG Card:

Provides three 1.5 A Class B NACs for Audio or DC notification.

Switches between two power audio input sources, for example, Flex-35/Flex-50-style dual-channel power stage switching.

Accepts Class A Adapter and Class B Expander for a total of six Class B NACs or three Class A NACs on each card that can be used with audio

or DC signaling.

Accepts constant supervision audio NAC module for a total of three Constant Supervision NACs on each card for use with audio signaling

only.

When configured for use with non-alarm audio, quickly and automatically switches to an audio source when a signal is detected at either

input.

Supports earth fault isolation in conjunction with the source NAC supplying the card input.

The XSIG Card also supports the WALKTEST system test as long as the following programming guidelines are followed:

• Custom Control must be written to turn on the NACs when the "WALKTEST Group Active" pseudo turns ON.

• Lists can be created for the NACs to allow you to have them turn ON when different groups are activated. However, a Custom Control equation

would be required for each WALKTEST group.
