Card with two audio outputs
with surveillance functions
UMX-2SA
1. INTRODUCTION
Card with two zone outputs for the COMPACT system. Incorporates DSP and surveillance functions.
DSP functions:
Controls for volume controls, bass and treble or 10-band graphic equalizer (30Hz / 60Hz / 125Hz / 250Hz / 500Hz / 1KHz / 2KHz /
4KHz / 8KHz / 16KHz) controlled by means the Call Point software Controls for volume, bass and treble through the Call Point
software.
Surveillance functions:
•
Monitoring of the speaker line: The card injects different frequencies in the speaker line; it then collects and analyses these
frequencies to determine the condition of the line (line open, short-circuit, low impedance, high impedance or line in good
condition).
•
Monitoring of the condition of the amplifier by analysing the audio signal and by detecting the 24 VDC it receives from the
amplifier.
The card occupies one slot on the matrix and may be inserted in slots 3 to 10 of the COMPACT audio matrix or in any of the
COMPACT-E slave matrix slots.
2. COMPONENTS
The card has 2 channels (“A” and “B”). Each channel corresponds to a different zone.
Each zone incorporates an audio output, fail and priority LED indicators, connections
to the speaker line and a FAIL output contact.
1)
POWER indicator light. Power LED indicator. Do not remove the card when it is
lit.
2) RJ45 connector for CHANNEL “A”. +4 dB audio output, balanced using a
transformer. The output level can be adjusted through the Call Point software.
RJ45 PIN OUT
Pin 1: AUDIO H (hot) output.
Pin 2: AUDIO C (cold) output.
Pin 3: +24 VDC input to monitoring the amplifier.
Pin 4: Not used.
Pin 5: Not used.
Pin 6: Priority output contact. Using jumpers and switches, this contact may be
configured as a voltage free contact or as an open collector output (see
section
3
. CONFIGURATION).
Pin 7: Not used.
Pin 8:
Metal Shield:
3) CHANNEL “A”. PRIORITY indicator. Indicates the activation of the priority
output contact of channel “A” (pin 6 of connector RJ45).
4) CHANNEL “A” FAIL indicator. Indicates FAIL output contact activated.
5) CHANNEL “A” LINE OUT connection. Connection terminals of the speaker line.
6) CHANNEL “A” LINE IN connection. Connection terminals to the amplifier speaker output lines.
7) CHANNEL “A” FAIL contacts. NO (Normally open) output contacts. Their activation is associated with the card surveillance
functions. Call Point software is used to configure in what cases the contact is made (when high or low impedance errors are
detected in the speaker line, short-circuit, line open or amplifier error...).
Using jumpers and mini-switches, the FAIL contacts may be configured as a voltage free contact or as an open collector output
(see section
3
. CONFIGURATION).

the connection between the pin 8
and the shielding of the connector to
the GND is made through the
internal jumper JP1, and the
connection to the earth of the
equipment is made through the
Internal jumper JP6.
