description The circuit is of a loop-mountable unit of a fire alarm system, and includes: an adjustable current source, arranged to adjust the current from the loop through the power control circuit based on a control signal; an inverting amplifier, arranged to provide the control signal to the adjustable current source in which the control signal is based on the loop voltage; and a damper having an input for connection to a loop and an output connected to the inverting input of the inverting amplifier such that the voltage at the output of the damper is smoothed with respect to the voltage at its input.
