Hochiki Ekho Hybrid Wireless Translator Module (EK-WL8-TRH)

The Hochiki Ekho EK-WL8-TRH is a fully intelligent wired-to-wireless Translator Module for the Ekho hybrid wireless fire detection range. It is wired directly to an addressable fire alarm loop running the Hochiki ESP protocol and communicates with Ekho wireless Expanders and field devices, allowing radio devices to be used alongside standard hard-wired devices. Each radio device takes its own loop address, so the wireless link is transparent to the end user.
