The design of the 1690 is ideally suited for demanding, high-traffic applications. The vertical rods and latch mechanisms are concealed in the vertical door stile, ensuring trouble-free operation. The cover plates and end caps are constructed of cast metal to hold up to rigorous use. A quick, single-point dogging feature in the housing deactivates the device and permits unrestricted traffic flow. This locking mechanism is designed to offer more versatility than crossbars, which require two-point dogging.
The Convenience of 1990 Rods/Latches. Since 1690 utilizes the same rods and latches as the 1990 crossbar device, existing 1990s can be replaced directly with the 1690 device - without removing the door!
The 1790 panic device carries the Underwriters Laboratory (UL) label and are approved for life safety. In addition, these exit devices meet the requirements of ANSI Grade I, 2001 revisions. Each feature an upgraded design that offers increased building security, eliminating the possibility of tampering and forced entry through the use of coat hangers or other tools. And the new streamlined design has no openings for chains reducing the risk of code infringements.
The 1790 rim device is typically used in applications where maintenance is a concern. The rim device has fewer parts and pieces than current exit devices which requires less maintenance and adjustment. The 1690/1790 pushbar width is 21/2˝. The devices project 3˝ in the neutral position, and 21/4˝ in the depressed/dogged position.
The 1490 device is built with rugged steel operating mechanisms and durable aluminum push bars and end caps. The electrified version includes a monitor switch. NOTE: The EL1490 and ED1490 Series is a handed device.
