From a recent thread re pyronix having rf issue with led street lighting.
There was a mention of dual channel helping this issue? Anyone else having rf issues with different gear on led lights?
Moved discussion to trade
iirc you cant. When I used to fit the 700l I used to fit a pot to the main board as a mod. Unless the 800l had one as std. You could put a resister in series with the speaker but that would lower the alarm volume as well
youu can use a 10A 8v transformer on your door bell but not a 1a 24v. they are 2 different voltages so you will need 2 supplies. one for your bell one for your other unit
or a transformer from 24v ac to 8v fed from the 24v one
its something to do with Part L

but this may only be new builds?
reading this I assume if the fitting exceeds 45 lumens per watt there is no limit? (table 42 page 81 of attachment)
my fitting is 17000 lumens at 150 watt on the front
