Alarm Controls Corporation PT5-152 Pneumatic Time Delay Release

Product Description

The Alarm Controls Corporation PT5-152 is a pneumatic time delay door emergency release device designed for controlled egress and access control applications. It uses air-based timing mechanics to introduce a deliberate delay before a door latch or electromagnetic lock releases, allowing building security personnel time to respond before exit is granted. Licensed security systems installers and access control technicians are the primary trades that specify and install this unit in commercial and institutional facilities.

This device is suited for use in commercial buildings, institutional facilities, and secured areas where delayed egress is required by code or facility policy. Typical installations include interior stairwell doors, secured lobbies, and controlled corridors where timed release of an electromagnetic or electric strike lock is necessary. It is sold as a single unit.

Key Features

• Pneumatic time delay mechanism provides adjustable release timing without electronic timing circuits
• Designed for emergency release applications at door egress points
• Sold as a single unit for straightforward one-door deployments
• Intended for commercial and institutional access control systems

Compatibility

Designed as an OEM-style replacement or new-installation component for pneumatic time delay door release systems in commercial access control and delayed egress applications.

Installation Notes

Installation should be performed by a licensed access control or low-voltage security systems technician familiar with delayed egress door hardware. Disconnect and lock out all power to connected electric locks or strikes before beginning work. Verify that the delayed egress configuration complies with applicable local fire and building codes, including NFPA 101 Life Safety Code requirements for delayed egress hardware. Do not alter the pneumatic timing mechanism beyond manufacturer-specified adjustments.
