Narrative:

At FL330, in WX, had both lockout and standby cabin pressure lights illuminated. Both reset utilizing QRH procedures. Approximately 15 mins later, with neither light illuminated, we got a cabin pressure aural warning. Rapid descent was initiated after declaring emergency and 10000 ft requested. As descent was initiated, the lights came on for a second time and were extinguished by QRH procedures once again. We got control of the cabin pressure by selecting maximum rate on the rate knob. The aircraft was leveled off a FL250. We had good fuel and range to destination, so we began a long descent to 13000 ft and cruised to destination without requesting any further assistance from ATC.
