Description
Inovonics EN4216MR EchoStream 16-Zone Multi-Condition Receiver with Relays | 902–928 MHz
The Inovonics EN4216MR EchoStream® 16-Zone Multi-Condition Receiver with Relay Outputs provides a flexible way to add up to 16 compatible EchoStream wireless transmitters to a hardwired security panel or standalone relay-based application. The receiver supports both single-condition and multi-condition transmitters, allowing separate alarm conditions from a compatible device to be assigned to specific relay outputs.
Five programmable Form C alarm relays and one dedicated Form C fault relay allow the EN4216MR to connect EchoStream wireless devices with control panels and equipment that accept conventional hardwired contact inputs. Each alarm or fault condition can be mapped to an output and independently configured for follower, latching, momentary, or toggle operation.
A two-line LCD simplifies programming and troubleshooting by displaying transmitter status, alarm and fault conditions, signal strength, output assignments, and a log of the 50 most recent events. Operating at 902–928 MHz in North America, the EN4216MR also provides transmitter supervision, case-tamper protection, RF-jam detection, internal antennas, and EchoStream frequency-hopping spread-spectrum technology.
Important Output-Capacity Notice: The EN4216MR provides six Form C relays: five alarm relays and one fault relay. It supports up to 16 registered wireless points, but multiple points or alarm conditions may share the same relay. Verify the number of separately identifiable outputs required by the connected panel before ordering.

How the EN4216MR Integrates Wireless Devices
Each compatible EchoStream transmitter or repeater is registered to one of 16 receiver points. Individual alarm and trouble conditions are then mapped to the desired Form C relay. When a registered wireless device reports a programmed condition, the assigned relay changes state and presents a conventional dry-contact signal to the connected panel or equipment.
This relay-based architecture allows organizations to add EchoStream wireless devices to many existing hardwired systems without requiring an RS-232 or IP software integration. The connected panel processes the relay activation as a conventional hardwired input.
What Is Multi-Condition Transmitter Support?
Some EchoStream devices can report more than one alarm input or operating condition. The EN4216MR can recognize as many as four compatible alarm conditions from a single registered security transmitter and map each condition to a selected relay output and output type.
Multi-condition support provides greater programming flexibility than a basic one-transmitter-to-one-relay receiver. However, the EN4216MR still has only five alarm relays. Multiple transmitters or conditions may therefore need to share an output unless the application requires five or fewer separately identified alarm circuits.

- Use an EchoStream survey kit to evaluate signal level and signal margin.
- Program a supervision interval longer than each transmitter’s check-in interval.
- Assign alarms, tampers, low-battery conditions, inactivity, and repeater power loss to the appropriate outputs.
- Use descriptive point labels to simplify future service and troubleshooting.
- Perform a walk test with every registered transmitter after installation.
- Test the installed security system regularly as directed by Inovonics.
Professional installation required: The EN4216MR should be installed and maintained by qualified security professionals familiar with relay wiring, alarm-panel programming, RF site surveys, and applicable security standards.
