Abstract

A door hold-open device which unlatches a held door based upon the occurrence of an unlatch condition includes a door latching mechanism (30) and a signal processing circuit that provides power to the latching mechanism The device conserves energy providing by withholding power from the signal processing circuit until an unlatch condition occurs. The device further prevents a door from being latched in an open position if (a) the power to the system falls below a predetermined threshold, or (b) a battery access member (21) is moved to permit disconnection of a battery (100).
