Resettable power is typically used to power beam detectors, flame detectors and conventional
4-wire smoke detectors. For circuits selected as Resettable, 24 volt power is always present at
the terminals unless a system reset occurs. If a system reset occurs, power is disconnected
from the terminals for 30 seconds, then re-applied.
