An intelligent operation feature on some models recognizes an already-closed door to prevent damage to the release mechanism. Fire Sentinel® is available with a battery back-up, strobe/sounder alarms and programmable multilingual enunciators to provide advanced protection against fire.

The 640 Model features a flat interlocking steel curtain that is factory finished with a rust-inhibited roll coating process that incorporates a baked-on primer and polyester topcoat to eliminate field painting and improve finish life.
