28/4/2004, · The value of R1 to set the ,alarm, trip level, and R4 to drop ,voltage, so X1 doesn't see more than 7 volts maximum. The ,voltage, developed by the R1/R2 divider that connects to the "Refrence" pin of the TL431 wants to be 2.5 volts when the battery is it's warning point (that would be 3 volts per cell used).
A universal ,low,-,voltage alarm, that can indicate possible system trouble. Use with the Wet Switch, SOS, Condensate Cop, CP-22 (all types) and all float switches on 24VAC control circuits. If an ,alarm, condition exists, the homeowner can turn the ,alarm, off with a silence button until service is obtained, however a red trouble LED will remain lit.
