Sti UB-1LTUL Universal Button with Latching Timer

Product Description

The STI UB-1LTUL is a universal push button with an integrated latching timer designed for use in door access and exit device applications. When activated, the button engages a latching mechanism that holds the output signal for a timed duration before resetting, allowing controlled door release without requiring continuous manual pressure. This type of device is commonly installed by electricians and low-voltage security technicians in access control systems where timed door strikes or magnetic lock releases are required.

The UB-1LTUL fits into exit device and push button applications in both residential and commercial settings. It is suited for interior door control points where a momentary press must trigger a held output, such as entry vestibules, secure corridors, or ADA-compliant egress stations. Installation is typically performed as part of a broader access control or door hardware system.

Key Features

• Integrated latching timer holds output signal after button press without requiring continuous activation
• Universal button format for broad compatibility with standard access control and exit device wiring schemes
• Single-unit packaging for straightforward replacement or new installation
• Categorized as an exit device and push button for door access control applications

Compatibility

Designed as an OEM-style replacement or new-installation push button for standard exit device and access control systems requiring a latching timer output.

Installation Notes

Installation should be performed by a licensed electrician or qualified low-voltage technician. Disconnect and de-energize all power to the door control circuit before beginning work. Follow local building codes and NEC requirements for low-voltage access control wiring. Verify that the latching timer duration is compatible with the door strike or lock hardware in the system before commissioning.
