Installation and Maintenance Instructions
Overview of Model E1 Intercom Station
The Federal Signal Model E1 ECHO Intercom Stations provide
safe and efficient two-way voice communications in large and
small ECHO Digital Intercom Systems. The E1 is ATEX and
IECEx certified for use in Hazardous Areas. The E1 ECHO station
provides instantaneous high-speed connections and clear, crisp
digital voice quality. Each station offers single-button all call,
priority emergency paging, group paging, speed dial, conference
call, and relay output.
The E1 station keypad is designed to provide tactile and audible
feedback via an external powered speaker for positive activation.
Any station can call any one or more stations in an ECHO Digital
Intercom System. With the headset or gooseneck microphone
options, each is capable of hands-free voice communication.
Because the ECHO Digital Central Exchange provides 30 channels
of simultaneous communication, calls are processed and connected
immediately without dial tone or delay.
Each E1 station is comprises a stainless steel enclosure containing a printed circuit board assembly providing the communications and safety functions. A relay output module is provided as a
standard feature. The relay operates when the intercom is in Ring
Mode. A single normally-open contact is provided with, which is
rated at 240 Vac, 3 A.
Each station may be programmed for four levels of privacy for
receiving calls: non-private, semi-private, full privacy, and do-notdisturb. The volume for voice and signal levels is easily adjusted
on the keypad.
The E1 Intercom Stations must be powered from an Echo Central
Control. The data/power is supplied from the Central Control line
cards. For full operational details of the Echo system, refer to the
instructions provided with the Central Control.
