Connect Emergency Input
Step 1:
Pull two 16 AWG (1.5mm
2
) wires from your Emergency contact location to the Echo
See Cable Routing and Conduit Access on page 14.
Step 2:
Strip 3/16” (5mm) of insulation from the ends of each wire.
Step 3:
Remove the two pin Emergency Input connector from J2 on the termination I/O board.
Step 4:
Loosen the terminal screws.
Step 5:
While maintaining the wire twist as close to the connection as possible, insert each wire
into the terminals on the connector.
Step 6:
Tighten the screws firmly to secure the wires into the connector.
Step 7:
Replace the connector to the termination board.
Determine Emergency Switching
Step 1:
Set the Emergency switch, S1 on the termination I/O board, to indicate the Emergency
Input contact closure type: Normally Open Closure (NO), Disabled (Dis), or Normally
Closed Closure (NC).
Connect Emergency Output (optional)
Step 1:
Pull two 16 AWG (1.5mm
2
) wires from your external emergency indication lamp to the
Echo Relay Panel through conduit.
See Cable Routing and Conduit Access on page 11.
Step 2:
Strip 3/16” (5mm) of insulation from the ends of each wire.
Step 3:
Remove the two pin Emergency Output connector from J3 on the termination
I/O board.
Step 4:
Loosen the terminal screws.
Step 5:
Insert the and insert the negative wire into pin 1 and insert the positive wire (this carries
24Vdc, maximum current draw of 25mA, to the lamp) into pin 2 of the terminals on the
connector.
Step 6:
Tighten the screws firmly to secure the wires into the connector.
Step 7:
Replace the connector to the termination board.
Connect EchoConnect
Using Belden 8471
Termination is available for up to four separate EchoConnect data runs and is topology-free.
EchoConnect includes one pair of wires (data + and data -) plus a separate ESD ground wire.
The total combined length of a EchoConnect wire run cannot exceed 1,640 feet (500m), with
a maximum distance of 1,313 feet (400m) between any two devices.
For systems utilizing Echo Preset stations, ETC recommends terminating the station data run
to the Echo host product with the station power supply enabled.
CAUTION:
Enable only one EchoConnect power supply per system. Reference the Power
Control Processor Configuration Manual, Station Power menu, for
instructions to enable or disable the power supply. Enabling more than one
power supply may interrupt communication and cause undesirable results.
