I've recently installed a 4 zone fire alarm panel within 2 flats. The alarm is connected to the downstairs flats meter and they are complaining about the running costs of it. The landlord is wanting me to produce an estimate on the yearly cost to run it, as well as 2 12v 1A doorbell transformers.
I'm a bit unsure how to work this out with the transformers?
This is the supply spec for the FA Panel
POWER SUPPLY SPECIFICATION
Mains supply voltage 230V 50/60Hz
Mains rated current 350mA maximum
Total output current limited to 1.5A @ 230Vac (ImaxA = 146mA)
Mains fuse (F1) 240V 1A HRC ceramic 20mm compliant with IEC (EN60127 PT2)
