what do you all think of the rokonet i wise for grade 3 installations and would you recomend any others .I know it all depends on the risk assesment

and type of building and insurance requirements.

Had to remove a couple of these detectors in a warehouse setting (fairly "friendly" environment) due to repeated false alarms and anti-masking errors; we replaced them with Pyronix TMD 15 which resolved all problems instantly.

We have also used the Pyronix Grade 3 Dualtecs with great success and so they are probably our detector of choice for Grade 3 installations.

The iWise have setup issues and a difficult top fitting (due to be changed I understand) which causes us to move away from them currently.

we all have our choices after testing and deciding on a sensor, we dont use the rokonet. I would advise you evaluate a few over a period before swettling on a g3 sensor (before you ask we use the honeywell 7550A)

Guardall DTSx+ as standard now.

thanks for the advice guys

Agreed, these sensors are brilliant. Tesco use them as their preffered DT as well.

Pyronix KX15DTAM problems a while back but sorted out now and SUPPORT IS GOOD.
