Hi all
Just a quick one.
For a fire alarm loop addressable system. Fp200 1.5mm cpc 1.5mm
To obtain R1+R2 would you treat the "loop" as a radial in effect and link brown and earth in connector then tester on other leg.
Or would you treat it as a ring and figure of eight and can be tested at any point.?
Thankyou
