Installation instructions for the Inovonics EchoStream EE4204/R Receiver, which adds up to four wireless transmitters to a security system with diversity reception.
Installation instructions for the Inovonics EchoStream® EE4204/R Receiver — adds up to four wireless transmitters to a security system, using diversity reception and advanced signal processing to minimize dead spots.
The EE4204/R receiver supports up to four wireless transmitters in any application. The EE4204R variant adds Form C relay outputs (vs. open-collector on the standard EE4204).

Same LED indicators as above, but reflecting the status of the transmitter currently selected via the Advance button, which scrolls through registered transmitters.
Connect power to the Power and GND terminals before startup. Power source must be 11–14 VDC, unswitched, uninterrupted, and regulated.
To meet ETSI requirements, Inovonics 868MHz-only products need EchoStream Select compatibility enabled if any older ES products are present in the system:
Default settings:
| Point | Supervision Window | Output Type | Switch (EE4204 only) |
|---|---|---|---|
| 1–4 | 4 hours | Follow | N/O |
| Fault (F) | N/A | Fault — Inactive follows; low battery & tamper latch | N/O |
To program a transmitter point or the fault output:
Registration confirmation: all alert LEDs turn off once the receiver receives the transmitter's registration message, and the point number LED lights for 2 seconds. If this doesn't happen, press Reset on the transmitter again.
Note: the only programmable parameter for the fault output is N/O vs. N/C. Selecting "F" auto-advances an EE4204 to the switch option; an EE4204R will not advance further.
Caution: this erases all programmed point, output, and language information.
Caution: mount away from metal (duct work, wire mesh, boxes), which reduces RF range. Use the provided anchors/screws to mount in a location accessible for future maintenance, then perform a walk test, activating each assigned transmitter and confirming an appropriate response.
