STI LT-1UL UL Latching/Timer Module

Ensure secure, dependable door control with the Safety Technology International LT-1UL UL latching/timer module. Designed for access control and security professionals, this digital timer/latch simplifies single-entry and timed-exit applications by latching Form C contacts while providing precise timing options (15, 30, 45 seconds or indefinite). Powered by 12–24 VAC/VDC, the LT-1UL supports both Fail Safe and Fail Secure supervised configurations so you can tailor behavior to your facility’s security policy. Its compact footprint makes it ideal for retrofits, kiosks, and tight panel spaces, while UL/cUL listing and a 3A contact rating deliver the reliability required for commercial surveillance and monitoring systems. The built-in reset feature prevents unauthorized re-entry by resetting after a single door cycle, reducing tailgating risk and improving traffic control. For integrators and facility managers needing a simple, durable solution for timed door control, the STI LT-1UL streamlines installation and operation. Add the LT-1UL to your access control or security door projects today.
