Options for Added Safety and Simplified Operations - An array of options allows the counter door to be adapted to virtually any job requirement. UL-listed FireLite® vision lites in 3-, and 1 1/2-hour labels allow visual access and light infiltration. UL-listed brush-type smoke seals enhance smoke retardation properties. The choice of a crank or electric operator simplifies door operation. The doors can also be custom-designed for conveyor openings. A variety of smoke detectors are also available when the door is equipped with the Fire Sentinel® release device
Fire Sentinel® for Fail-Safe Protection - The Fire Sentinel® is a UL-listed, fail-safe device. This time-delay release mechanism provides a 10-second time-delay release as well as an independent 10-second time delay on power loss to control the closure of the door after an alarmed event while eliminating false closures due to momentary power outages. 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
Galvanized Steel - When you opt for a 22-gauge galvanized steel, these counter doors deliver unsurpassed strength, durability and aesthetic appeal. 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 top coat to eliminate field painting and improve finish life
