Diagnostic Select selects a specific remote amplifier
to examine specific trouble conditions for the remote
amplifiers. The fault LEDs with wrench graphics represent
the amplifier selected.
Trouble Silence Manually silences the local trouble
sounder.
Console Lamp Test Tests the local LEDs and sounder.
4.2 LED Indicators
Fire System Active Green LED that turns on steady
when the FACP is in alarm.
MNS Control Green LED that turns on steady when an
operator has initiated a mass notification event by pressing
the MNS Control button or by pressing an MNS message
button.
System Control Green LED that turns on steady when
the main console has control of the audio system.
System in Use Green LED text that turns on steady
when the main console, an LOC, an RPU, or an RM has
control of the audio system.
Speaker Zones 1-24 Green LED per speaker circuit
button that turns on steady when a speaker circuit has been
selected and is active. Yellow LED per speaker circuit
button that turns on steady when a speaker circuit fault
exists or when the speaker circuit has been turned off after
having been automatically turned on by the FACP.
OK to Page Green LED text that turns on steady when
the system is ready for paging.
Microphone Trouble Yellow LED text that turns on
steady to indicate a microphone wiring fault.
Messages 1-8 Red LED per message button that turns
on steady when the message has been selected and blinks
when the message has been overridden. Yellow LED per
message button that turns on steady when no message has
been recorded or there is an associated command input
fault. All eight message button LEDs will turn on steady to
indicate a message generator fault. 8th button "shift" key
red off when viewing messages 1-7 and on steady when
viewing messages 8-14. Yellow LED will turn on
indicating a message trouble in the group of messages not
currently being viewed.
Remote Amplifiers 1-8 Fault Yellow LED per remote
amplifier that turns on steady when an amplifier has a
fault.
LOC/RPU/RM 1-8 Fault Yellow LED per remote
console that turns on steady when a remote console has a
fault. Green LED per remote console that turns on steady
when a remote console is active.

5 Wiring
Wiring for the Local Operator Console is accomplished
between TB24, TB12, and TB22 on the ECC-50/100 main
control board to TB3, TB4, and TB5 on the LOC. If the
ECC-LOC is the last device on the audio and data bus
chain, signal terminations are required. For the external
data bus, a removable jumper must be on pins 1 and 2 of
JP2. If the ECC-LOC is not the last device, the jumper
must be on pins 2 and 3 of JP2 as shown below. For the
external audio riser, termination (15K ohm resistor) must
be connected to pins 5 and 6 on TB5. A ferrite clamp
(P/N: 50116546-001) must be installed around all wires in
both the input and output wire runs inside the ECC-LOC
cabinet as shown below. Refer to the ECC-50/100 Manual
#LS10001-000FL-E for more information.
