It combines a momentary push switch with a pneumatic timing mechanism, allowing a controlled delay before a connected latch or electric strike releases or re-engages. This type of device is commonly installed in commercial door hardware systems where timed egress or delayed access release is required. The 453PNV ships as a single unit and is suited for integration into low-voltage access control circuits managed by licensed security or door hardware technicians.\u003c\/p\u003e\n\u003cp\u003eThis device is appropriate for commercial and institutional installations where a timed pneumatic release is needed at an exit or controlled-access door. Typical applications include office suites, institutional corridors, and secure vestibules where code-compliant delayed egress or timed unlock functions are required. The finish designation 628 indicates a satin aluminum appearance, which coordinates with standard commercial door hardware in aluminum-frame storefronts and hollow-metal door assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIntegrated pneumatic timer eliminates the need for a separate electronic time-delay relay\u003c\/li\u003e\n  \u003cli\u003eMomentary push button actuation initiates the timed release cycle\u003c\/li\u003e\n  \u003cli\u003eFinish 628 satin aluminum suits standard commercial aluminum door hardware\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging for straightforward replacement or new installation\u003c\/li\u003e\n  \u003cli\u003eDesigned for use in low-voltage access control and exit device circuits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for commercial exit device and access control systems requiring a push button with pneumatic timer function.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed door hardware technician or access control specialist familiar with local building codes and fire egress requirements. De-energize all connected access control circuits and verify the door hardware assembly is in the unlocked or safe position before beginning work. Consult the applicable building and fire codes, including IBC egress provisions, to confirm that pneumatic timed-release devices are permitted for the intended application. Do not exceed the rated voltage and current for the connected circuit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each (EA)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Package\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: 628 Satin Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Exit Devices and Push Buttons\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SDC - SECURITY DOOR CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 453PNV\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SDC","offers":[{"title":"Default Title","offer_id":51688651620658,"sku":"453PNV","price":769.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d0d3f595aca8f96003615e493ec6717.jpg?v=1788248610","url":"https:\/\/voomisupply.com\/products\/sdc-453pnv-push-button-pneumatic-timer-exit-device","provider":"Voomi Supply","version":"1.0","type":"link"}
