1.6 What’s in the Carton

• Two drywall mounting anchors.
• Two wall mount screws.
• One frequency band selection jumper.

2 Installation and Startup

2.1 Installation Notes

• These products are designed to be maintained by professional 

security technicians.

• Products are tested for indoor use.
• All products should be manually tested weekly.

2.2 Power Cabling

Before beginning startup, you will need to connect power to the receiver. To 

connect power to the receiver:

1.

Connect power cabling to the Vs and GND connections.

• The power source must be 11-14 VDC. The power supply must be 

unswitched, uninterrupted, and regulated.

2.3 EchoStream Select Compatibility

To meet ETSI requirements, Inovonics has developed a new line of EE 

868MHz-only products.  These new 868MHz-only products are compatible 

with older systems that include EchoStream Select products. If you are 

using any ES products in your current system, you will need to enable 

EchoStream select compatibility on this 868MHz-only product; if you are 

not using any EchoStream select products, skip to section 2.4, “Input/

Output Cabling”.
To enable EchoStream Select compatibility:

2.

Place a selection jumper on the ES selection pins.

Note: 

Selection jumpers are included in the EE4232MR hardware packet.

3.

Reset the receiver or cycle power.

2.4 Input/Output Cabling

Connect the inputs and outputs per your specific application:

4.

Connect cabling to the clear to set output.

• The optional clear to set output is a relay output that provides a clear 

to set signal to the control panel that can be used to ensure all security 

devices in the system are active before allowing the system to be set. 

If used, the system cannot be set if the receiver has not heard from 

any registered wireless devices within the last 20 minutes. 

5.

Connect cabling to the tamper output.

• The optional tamper output is a relay output that reports receiver case 

tamper to an external device.

6.

Connect cabling to the jam output.

• The optional jam output is a relay output that is active when noise 

thresholds on all transmission channels remain above a 

predetermined value for 30 seconds in any 60 second window.

7.

Connect a momentary switch to the reset input and ground.

• The optional reset input circuit permits installation of a remote 

momentary normally open (N/O) switch to clear faults, unlatch 

outputs, and reset the receiver to a normal state.

8.

Connect cabling to the output terminals.

9.

Mount the Receiver

Caution: 

Mount the receiver in a location removed from metal. Metal 

objects (duct work, wire mesh screens, boxes) will reduce RF range.

10.

Use the provided anchors and screws to mount the receiver in a 

location accessible for future maintenance, making sure the housing is 

flush with the wall and the back tamper switch is actuated.

11.

After all transmitters have been registered, perform a walk test, 

activating each transmitter assigned to the receiver and ensuring a 

good signal.

2.5 Select Display Language

On initial startup you will need to select the display language. Once 

selected, the language will be maintained unless changed using the 

C

ANGUAGE

 option in the I

NSTALL

 & S

 menu. To change the 

display language, see “Select Language” on page 5.

3 Factory Configuration Defaults

The EE4232MR arrives with the outputs pre-programmed. If the default 

programming is sufficient for your site, you can advance directly to section 

“Register Transmitter” on page 6.
