Alarm Controls Corporation PN5-111 Pneumatic Time Delay

Product Description

The ALARM CONTROLS CORPORATION PN5-111 is a pneumatic time delay device designed for use in door hardware and access control applications. It operates without electrical power, using air-pressure mechanics to introduce a controlled delay in the range of 2 to 60 seconds. This adjustable range makes it suitable for sequencing door closers, exit devices, and push-button assemblies where a timed hold-open or delayed-release function is required. Licensed electricians, security technicians, and door hardware installers typically work with this type of component during new installation or retrofit of egress and access control systems.

The PN5-111 is used in commercial and institutional settings where timed door control is needed without reliance on low-voltage electronics. Typical applications include vestibule sequencing, controlled egress corridors, and exit device timing in buildings subject to fire and life safety code requirements. It is sold as a single unit and fits into systems where a pneumatic delay is specified in place of an electronic timer.

Key Features

• Adjustable time delay range of 2 to 60 seconds
• Pneumatic operation requires no electrical power source
• Compact single-unit form factor suitable for door hardware integration
• Applicable to exit device and push-button control assemblies

Compatibility

Designed as an OEM-style pneumatic time delay replacement for exit device and push-button control systems in commercial door hardware applications.

Installation Notes

Installation is typically performed by a licensed door hardware technician or security systems professional. No electrical power source is required, but surrounding access control or exit device circuits should be de-energized before beginning work. Follow applicable local building codes and life safety standards, including NFPA 101, when integrating time delay devices into egress hardware. Do not exceed the maximum delay range when adjusting the pneumatic mechanism, as improper settings may conflict with fire code egress timing requirements.
