HES PS5-151 Pneumatic Time Delay, Clear Finish

Add a pneumatic timing function to emergency-exit hardware with a component specified for that application and finished in clear. Pneumatic timing uses controlled air movement as its operating principle, making this item a mechanical timing component rather than an electronic controller. The clear exterior finish supports installations where the hardware is visible as part of an architectural door opening. HES PS5-151 is intended for emergency hardware contexts requiring a time-delay function. Its application should be evaluated with the complete door, frame, exit hardware, and emergency-release arrangement. The timing component is only one part of the opening assembly; door hardware selection must account for the required emergency operation and the physical arrangement of the installed hardware. Within the PS5 pneumatic time-delay range, this configuration is distinguished by its clear finish and emergency designation. Those two details matter when replacing an existing component or matching visible hardware at an installed opening. Use the ordered code when comparing replacement hardware, and verify the required function and finish against the equipment already installed before selecting a replacement.
