ElahoAccess Interface
Electrical Requirements
The ElahoAccess Interface requires 24 VDC (Class 2) power, supplied by an
external 24 VDC power supply. Termination for this connected is provided on
a removable pluggable connector, accepting 26-14 AWG (0.4-2.5 mm
2
) wires,
typically a black and red wire pair.
Note:
NEC Class 2 product to be wired in accordance to NEC Article
725 and local jurisdiction requirements.
EchoConnect
The Interface connects to the EchoConnect station communication bus.
EchoConnect is a bidirectional protocol that uses one pair of wires (data + and
data -). Echoflex recommends using Belden 8471 (or approved equal) Class 2
wire. The total combined length of an EchoConnect wire run (using Belden
8471, or equal) may not exceed 1,640 feet (500 m).
Note:
All control wiring should be installed and terminated by a
qualified installer and should follow standard wiring installation practices.
Leave approximately 8" (20 cm) of wiring in the back box for connection
and to allow slack for future service needs.
Note:
Echoflex requires that all Elaho stations and devices be grounded
for ESD protection. Pull an additional 14 AWG (2.5 mm
2
) wire for
grounding when control wires are not installed in grounded metal conduit.
