The 70.7 V
RMS
Transformer can be used to convert the integral 25 V
RMS
amplifier for installations
where 70.7 V
RMS
speakers already exist or are to be installed. Speaker wiring continues to be super-
vised during standby, alarm and while background music is playing when transformer is installed.
The transformer comes pre-installed onto a bracket for mounting to the chassis. Installation onto

2.14 Addressing External Data Bus Devices
The table below defines an address map for the external data bus devices which include the
ECC-LOC, ECC-RPU, ECC-RM, ECC-50DA, and ECC-125DA. Dipswitches are used on each of
these devices to set the bus address in order to properly communicate with the ECC-50/100 panel.
Any combination of up to eight (8) remote consoles (ECC-LOC, ECC-RPU, and ECC-RM) can be
