HILDEBRAN, N.C. — Security and automation solutions manufacturer ELK Products today announces expanded wireless capabilities for the Alarm Engine platform with the introduction of the ELK-AERF3H 345 MHz receiver and ELK-AEXRFA3H 345 MHz receiver and RF bus adapter.
Together, these new solutions “enable support for 345 MHz wireless sensors, giving installers more flexibility than ever before,” according to the company announcement.
The AERF3H is an on-board wireless receiver designed specifically for the Alarm Engine, providing a “clean and efficient way” to add 345 MHz sensor support directly at the panel. For applications requiring extended coverage, the AEXRFA3H allows additional receivers to be connected to the E27 data bus, enabling installers to place receivers throughout a property.
By supporting up to four data bus-connected receivers, the system “can significantly improve signal coverage and reliability—ideal for larger homes or light commercial installations where wireless performance is critical,” according to the ELK Products announcement.
What Do the New ELK Products Do?
The AERF3H and AEXRFA3H support a range of 345 MHz wireless sensors, including those from the Honeywell 5800 Series, MaxOut Technology 345 MHz sensors and other manufacturers operating on the 345 MHz frequency.
This compatibility “allows for easier system takeovers and expanded sensor selection across intrusion, life safety and environmental monitoring applications,” the company announcement says.
Key benefits of the AERF3H and AEXRFA3H include:
- Native support for 345 MHz wireless sensors
- Compatible with Honeywell 5800 Series, MaxOut Technology and other 345 MHz
devices - On-board receiver option with the AERF3H for streamlined installation
- Expandable coverage using AEXRFA3H data bus interfaces
- Support for up to four remote receivers for enhanced signal reliability
- Ideal for retrofits, takeovers, and large-area installations
“The addition of 345 MHz wireless support gives our dealers more flexibility in both new installations and system upgrades,” says Robert Dant, director of sales and marketing, in the company announcement. “With scalable receiver placement and seamless integration into the Alarm Engine, we’re making it easier to deliver reliable wireless performance in any environment.”
The ELK-AERF3H and ELK-AEXRFA3H are available now through authorized ELK distributors.
