FMR15108R & FMR15108
Eight Channel FMR Series Receiver. FMR15108R
The eight channel receivers are available in two versions:
- FMR15108R – with relay output
- FMR15108 – with open collector outputs
Each version is carefully designed to cater to specific needs across various industrial and commercial applications. Operating on the 151MHz frequency band, these receivers are fully compatible with the FMT series of long range transmitters, allowing for an impressive operating range of up to 5,000 meters.
The FMR15108R receiver offers flexible relay modes that can be set to momentary, latching, or delayed Off. These different output modes can be easily selected using the onboard 4-way dipswitch, providing several preselected mode combinations to suit a wide range of application.
Users can select from eight different narrowband frequencies and program an unlimited number of transmitters to the receiver. Programming the transmitter is straightforward, requiring only the matching of the 12-way dip switch settings between the receiver and the transmitter.
The 151MHz frequency band is ideal for long range communication, making these receivers an excellent choice for applications where maintaining a strong and stable connection over vast distances is crucial.
The FMR15108R receiver is tailored to meet the specific frequency requirements of different regions: 151MHz for Australia, 154MHz for the USA and Canada, and 161MHz for New Zealand. This ensures optimal performance and compliance with local regulations, making the receiver versatile and suitable for global applications.

Elsema: Frequently Asked Questions
What is the FMR15108R receiver designed for?
The FMR15108R is a high-performance, 8-channel receiver specifically designed for long-range industrial and commercial applications. It allows users to control up to eight independent devices or functions wirelessly over significant distances.
What is the maximum operating range of the FMR15108R?
When paired with Elsema’s FMT series transmitters and a correctly tuned antenna (such as the ANT151M), the receiver can achieve a line-of-sight operating range of up to 5,000 metres.
What are the power supply requirements?
The FMR15108R is built for flexibility, accepting a wide supply voltage range of 12 – 24 Volts AC or DC. This makes it compatible with most standard industrial power systems and battery setups.
What is the difference between the FMR15108R and the standard FMR15108?
The “R” in FMR15108R stands for Relay. While the standard FMR15108 uses open-collector outputs, the FMR15108R features eight independent relay outputs (Common, Normally Closed, and Normally Open), which are capable of switching higher voltage and current loads directly.
What relay output modes can I select?
The receiver offers several user-selectable modes via an onboard dipswitch, including:
- Momentary: The relay stays active as long as the transmitter button is held.
- Latching: The relay toggles between “on” and “off” with each press.
- Delayed Off: The relay turns off after a preset time delay.
- Mixed Modes: Combinations where some channels are momentary and others are latching.
How many transmitters can be programmed to one receiver?
The FMR15108R has a storage capacity for an unlimited number of FMT series transmitters. This is achieved by matching the 12-way dipswitch code on the receiver with the codes on any number of transmitters.
Can I use the FMR15108R in environments with high electrical noise?
Yes. The FMR15108R is highly resistant to natural and man-made electrical interference. It is an ideal choice for heavy industrial sites, pump stations, and agricultural environments.
How can I check if the receiver is getting a strong signal?
The board features a built-in signal strength indicator consisting of five green LEDs. This diagnostic tool allows installers to see the quality of the incoming signal in real-time and identify any potential background noise or interference.
Can the operating frequency be changed?
Yes. Users can select from 8 different frequencies using a 3-way dipswitch. This feature allows multiple systems to operate in the same vicinity without interfering with one another.
Does the FMR15108R come with an enclosure?
The standard FMR15108R is supplied as an open-circuit board for integration into existing control panels. If you require a weatherproof version for outdoor installation, the FMR15108RE model comes pre-housed in an IP-rated case.
