The ECC-RM is an optional Remote Microphone
compatible with the ECC-50/100 Emergency Command
Center. ALL CALL paging can be broadcast over the
speaker circuits by depressing the microphone's push-totalk switch. The RM requires an external data bus
connection, an external audio riser connection, and an
external operator interface power connection (24 volts
DC) from the ECC-50/100 main console. Refer to the
ECC-50/100 Manual, LS10001-000FL-E, for more
information.

3 Wiring
Connections are made from TB24, TB12, and TB22 on the
ECC-50/100 main control board to TB3, TB2, and TB1 on
the RM. If the ECC-RM 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 JS4. If the ECC-RM is not the last device, the
jumper must be on pins 2 and 3 of JS4. For the external
audio riser, termination (15K ohm resistor) must be on
pins 4 and 5 on TB2.
