Ekho Hybrid Wireless

Hochiki's New Hybrid Wireless Fire Detection Range



Expander Network Example



A New Generation of Hybrid Wireless Fire Detection



Ekho is a wireless based family of products which can be fully integrated into Hochiki’s renowned ESP intelligent hardwired system. 


At the core of the system is the wireless Translator module. It is hard-wired to the fire alarm control panel loop and communicates continuously with the wireless devices. Wireless Expander modules are used to extend the radio mesh network, increasing the reach and capacity of the overall system.


Ekho is the next generation of hybrid wireless fire detection from Hochiki and supersedes the FIREwave system.

Self-Configuring Mesh Network



The Ekho Expander modules create a self-configuring mesh network, which constantly relays field device signals back to the Translator module. Each wireless device determines which Expander has the strongest signal path and automatically connects to it. The Expander mesh network guarantees an “always on” connection between the wireless devices and the Translator/fire control panel.


Self-Configuring Mesh


Self-Configuring Mesh provides:


  • High level of reliability
  • Automatically adapting to changing operating conditions: all devices automatically choose a parent expander depending on the quality of connection
  • A simple design and commissioning process



Advantages for installers


  • Simplified design and planning process
  • Faster commissioning process
  • Less time on site.


Expander Network 1


In this example, the Ekho sensor is connected to the Translator via Expander 1, as it is the strongest signal pathway.


Expander Network 1


If the signal to Expander 1 is compromised, the sensor automatically finds and connects to an Expander with the next strongest signal pathway, in this example, Expander 2.



Ekho is available in various operating frequencies and support is available from our regional offices. Product part codes may vary depending on the region, please contact your local office for details.

Hybrid Wireless Devices

Optical, Thermal and Multi Criteria Sensors

Ekho sensors are supplied in three variants: Optical, Thermal and Multi Criteria, which cover a wide range of applications. The Optical and Multi Criteria detectors feature double dust traps and adaptive signal processing to prevent false alarms. Thermal detectors can respond to a fixed temperature threshold, or detect a rate of rise in temperature.


The range of Ekho devices provides a visually attractive wireless fire detection solution, encompassing a wide variety of installation types and sizes.


In addition, Hochiki’s dedicated team of technicians provides support to customers, and ensures that installation and maintenance processes remain transparent, effortless and focused on customers’ requirements.
