The EK-WL8-TRH is a fully intelligent wired to wireless Translator Module. Compatible with the Hochiki ESP protocol, the module allows the use of
fully intelligent radio (wireless) field devices alongside standard hard wired devices.
The Translator Module allows the connection of up to 126 Expanders and radio field devices to an addressable fire detection loop. Multiple Translators
can be used on a system providing the system has sufficient loop power and addresses available.
The Translator Module incorporates a Loop Short Circuit Isolator and an OLED display to allow the Translator to be easily programmed.
Each radio field device takes a loop address making them fully intelligent and their radio connectivity transparent to the end user. System parameters are programmed via the Translator Module and a PC link. The Translator Module automatically manages sensor radiated power depending on the device communication quality. The unit is fitted with two Internal antennas which reduce radio fade and ensure reliable radio communication. Optional back box available.
