Hochiki

RSM-WTM Hochiki FIREwave Wireless Translator Module

The RSM-WTM is a fully intelligent wired to wireless Translator Module. Completely 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 32 radio field devices to an addressable fire detection loop. Multiple Translators can be used on a system providing the system has sufficient loop addresses avaliable.

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 detector radiated power depending on the device communication quality.

The module is housed in an IP65 housing making it suitable for mounting in wet environments and outdoors. The unit is fitted with two orthogonal antennae which reduce radio fade and ensure reliable radio communication.

Frequently Asked Questions

I need to replace an existing RSM-WTM, what are my options?

The RSM-WTM has now become end of line with no new units being manufacturered by Hochiki. Should you need to replace a RSM-WTM on an existing system then the recomended solution from Hochiki is to replace this with the equivalent translator from their current Ekho system. You are able to run them in parallel (separate systems on the same panel/loops) however any wireless devices associated with the previous RSM-WTM translator would need to be replaced with the equavilant Ekho devcies.

Do I require a lead to programme the RSM-WTM?

Yes, you will require a 9 Pin Serial Lead Male to Female.
