EK-WL8-TRH is an intelligent transceiver module that functions as a wired-to-radio interface.


Compatible with the Hochiki ESP protocol, the module enables the use of fully intelligent (wireless) radio field devices together with standard wired devices.


Allows connection of up to 126 expanders and devices to the addressable fire panel loop. Several can be used in a system as long as the system has sufficient loop power and available addresses.


Built-in short-circuit isolator and OLED display for easy programming.


Each device occupies an address in the loop, and is programmed through the module and/or PC.


Automatically manages the radiated power of the sensor according to the communication quality of the device.


It is equipped with two internal antennas that reduce signal fading and ensure stable communication.


Optional back box available.
