Choosing Von Duprin Guard-X and Exit Alarm Kits
Von Duprin alarmed exit hardware provides an audible warning when an opening is used under the conditions specified for the device. The first buying decision is whether the project needs an exit alarm lock or an alarm kit for existing hardware. These are different product types with different installation requirements. Identify the door and any installed exit device before selecting a model, and review the intended alarm operation as part of the overall opening requirements.
The 2670 Guard-X is an exit alarm lock intended for secondary emergency exits. Its emergency-exit identification and audible alarm help discourage unauthorized use of the opening. The listed package includes a strike, screw pack and battery; check the cylinder requirements separately before ordering. Compare the manufacturer dimensions and installation information with the door rather than assuming that a complete lock will replace an existing panic bar without changes. Review any outside-access requirements and the appropriate supporting hardware at the same time.
A 99 Series alarm kit is a different purchase from the Guard-X lock. It is intended for use with compatible exit-device hardware rather than as a complete replacement device. The listed kit is identified as a less-switch configuration, so verify the required switch arrangement and what is already installed. Match the kit to the exact device series, size and configuration, then review the included components and power requirements. Do not assume that the kit alone supplies every component needed for the planned installation.
Alarm operation should be reviewed separately from the way the door releases. An audible alarm does not, by itself, establish that a product provides delayed egress or remote access control. Confirm the operating sequence, arming and disarming method, and any required connections in the documentation for the selected model. For an existing opening, record the device identification and current configuration so a proposed kit can be checked against the equipment actually on the door.
Before purchasing, compare the product type, mounting requirements, package contents and intended use in one review. Confirm suitability for the particular opening, including any required hardware listing, rather than inferring it from the presence of an alarm. Use the wider Von Duprin exit-device collection when selecting a complete device for a new project, and the parts collection when servicing an existing assembly. Keep the installed model and component information with the facility maintenance records for future replacement orders.
