A new series of recessed exit devices from Von Duprin combines architecturally sound aesthetics with superior functionality. Called INPACT^TM, the new design is available in an array of finishes, with a broad range of features and options that includes electric latch retraction and two-point or single-point LBR latching. The recessed configuration is well-suited to applications that must meet clear-width requirements for cross-corridor doors.

The new INPACT recessed exit device is available with a smooth pushpad, designated as Series 9447, or with a grooved pushpad, designated as Series 9547 devices. Both are concealed vertical rod devices. They replace the previous Series LP9247 devices.

Aesthetics Plus Practicality
The design of the new INPACT device combines several physical advantages with a bold new styling that is architecturally compatible with a wide variety of environments.

The wide pushpad incorporates smooth convex lines invites users to push the device. The wider, slightly contoured pushpad enhances ease of operation and accommodates those with disabilities. The end caps incorporate a rolling contour that protects the device and door, as well as gurneys, carts and dollies, by absorbing the initial shock of impact and deflecting the object away from the door. The smoothly contoured device presents no corners or surfaces that can engage clothing or other items as pedestrian traffic moves past.

The devices are available in seven colors, including polished and brushed chrome, polished and brushed brass, Duranodic, aluminum, and dull bronze. Durable die cast aluminum end caps are available in standard black as well as optional matching or contrasting finishes.

Architects who have seen the new device say they appreciate that the device does not make a separate design statement from the rest of the building, yet does not hide the fact that it is an exit device.

Mechanically Versatile
The recessed design makes the devices ideally suited for cross-corridor doors that must meet the clear width requirements that have become a concern, particularly in California. While conventional exit devices may extend as much as 3" to 4" from the door surface, the INPACT devices only extend 1-5/8". When the door is in the open position, the INPACT design mechanically holds the pushbar in the retracted mode to minimize its projection to 1-1/4" for optimum clear-width benefits.

In addressing the clear width issue, the new design has not sacrificed durability. Heavy-duty construction and simple, yet effective mechanism design are combined with traditional Von Duprin quality to ensure long and trouble-free service life. The devices are UL listed for Panic Hardware and Fire Hardware, as well as a one-million cycle test conducted under the supervision of certified technicians from an independent testing laboratory.

The device is easy to install, with only six mounting fasteners needed to mount the mechanism and pushpad in place. The end caps are then fastened with 3-1/2" stainless steel fasteners to ensure accurate alignment. These mounting screws are recessed inside the door where they cannot be seen during normal operation. The installation process typically takes half the time required for conventional exit devices. Adjustment of the concealed vertical rods also has been simplified and can be performed by simply removing the latch-side end cap. There is no need to remove the door from its hinges.

In developing the new design, Von Duprin worked closely with Steelcraft in the initial design and testing process. However templating and prepared doors to fit the new device also will be offered by most of the popular hollow metal door manufacturers.

A wide range of product variations is available, all with either smooth or grooved pushpads. The 94/9547 devices are available for pairs of hollow metal doors up to 8'0" x 10'0". For the opposite side of the door, lever trim, thumbturn and dummy pull trim options are offered.

While the basic concealed vertical rod design includes both top and bottom rod, an LBR (less bottom rod) version also is available. It includes a spring-loaded auxiliary latch that installs in the lower door edge. The latch is designed to release from one door leaf and engages the other door when exposed to heat during a fire. When the auxiliary latch releases, it keeps the doors in alignment and closed during the fire. This option is well-suited to meet traffic control and fire door latching requirements. However, it is not recommended for exterior doors, since it does not provide the same level of security as the two-point latching of top and bottom rod designs.
