Product Description
1.5 Optional Equipment
ECC-50W-25/70V Audio Amplifier Modules
An optional second audio amplifier can be plugged into connectors J10 & J11 located in the upper
right of the main control board in the ECC-50/100. This amplifier also provides 50 watts of power
at 25 V
RMS
or 70 V
RMS
, depending on the model, and can therefore be used to expand system power
to 100 watts (providing dual 50 watt speaker circuits) or it can be used as a backup amplifier. The
output is power-limited (Class 2) and speaker circuit connections to it are provided on the main
control board and optional speaker circuit expander module. The circuit can be wired for Style Y
(Class B) or Style Z (Class A) operation.
LEDs are provided to indicate Amplifier Supervision (green indicates amplifier is functional) and
Circuit Trouble (yellow indicates field wiring fault or amplifier fault). The LEDs are only visible
with the panel door open.
ECC-CE6 Circuit Expander Module
This optional module plugs into connector P1 in the upper middle of the main control board. The
ECC-CE6 adds three primary speaker circuits to the ECC-50/100. The ECC-CE6 adds three sec-
ondary circuits to the system when the ECC-50W-25/70V Audio Amplifier Module is also
installed.
ECC-XRM-70V Transformer 70.7 V
RMS
This optional module plugs into connector J12 of the main control board and provides conversion
for the integral audio amplifier from 25 V
RMS
to 70.7 V
RMS
at full rated 50 watts output power.
ECC-FFT Fire Fighter Telephone
The ECC-FFT has a telephone handset and user interface that allows an operator to communicate
with remotely located telephone handsets in a building. It is housed in its own cabinet with key
lock. It requires an external operator interface power connection (24 volts DC) from the ECC-
50/100 main console or it may be powered from an external 24 VDC power supply such as
HP300ULX. The ECC-FFT provides supervision, annunciation, and control for the local handset
and for up to 24 remote telephone handsets. It provides indications of phone activation and corre-
sponding trouble conditions. Refer to the ECC-FFT Fire Fighter Telephone manual.
ECC-50DA Distributed (Remote) Audio
The ECC-50DA is a 50-watt audio amplifier (audio booster) with its own cabinet and key lock. It
requires an external data bus connection and an external audio riser connection from the ECC-
50/100 main console. The unit comes standard with 4 speaker circuits. An option card, ECC-CE4,
provides 4 more speaker circuits for a total of 8. Speaker circuits are activated/de-activated manu-
ally or automatically by the ECC-50/100 main console. The unit is capable of either 25 V
RMS
or
70.7 V
RMS
operation. Refer to the ECC-50/125DA Distributed Audio manual.
ECC-125DA Distributed (Remote) Audio
The ECC-125DA is a 125-watt audio amplifier (audio booster) with its own cabinet and key lock. It
requires an external data bus connection and an external audio riser connection from the ECC-
50/100 main console. The unit comes standard with four (4) speaker circuits. An option card, ECC-
CE4, provides 4 more speaker circuits for a total of eight (8). Speaker circuits are activated/de-acti-
vated manually or automatically by the ECC-50/100 main console. The unit is capable of 25 V
RMS
operation. Refer to the ECC-50/125DA Distributed Audio manual.
NOTE: Any combination of up to eight audio boosters comprised of ECC-50DA and ECC-125DA
can be used in the system. Their external data bus addresses must be unique and must be
sequential. Addresses are set via dipswitches on each unit's PC board. Refer to Section 2.14 on
page 54.
