Yes but only using Hyfire wireless on advanced panels
Argus protocol if i remember rightly

Yep thats the badger. Had to install and commission this hyfire wireless kit on an Advanced panel with Argos Vega protocol (done the course 1 day before it was supposed to be signed off!!) all sorts of problems now with it as they didnt put the expander and translator in a correct position so the Db levels to the detectors keep dropping out. Think our designer now wished he had thought of wiring it

The translator should be on the loop and expander is only to boost the range.....not to sure will have to check, but think sounder levels and tones are controlled by the advanced panel and can altered for each individual sounder base hence all need to be set by panel or will just stay at default of level 4

Indeed the translator is on the loop on outside of the building and across a car park to two other buildings. Had a survey by hyfire themselves. Db levels are used for the detectors plus call points (via laptop) if i remember correctly if it goes below 13/15/17db the expander kicks it to wake up.
Decent stuff as long as it says above 21db usually.
Neat way to add them onto a system too. Its different

sorry just understanding your post the db is not sound level but radio transmission level........well this is part and parcel of low powered radio equipment on 858mhz.....it is prone to variate with envioroment issues...the weather, a van blocking the transmitter, but the idea of the test is to make sure theses issues are covered...and this cant be covered in just one day
Would suggest this system requires another expander and retesting for transmission levels
