Securitron Time Delay Relays

Overview

The SECURITRON -U.S. XDT-12 is a 12-volt DC time delay module designed for use in electronic exit device applications. It introduces a programmable or fixed delay into the door release sequence, allowing controlled egress without immediate lock release upon activation. The module is UL listed, meeting code-compliance requirements common in commercial and institutional door hardware installations. Electricians and low-voltage security technicians are the primary trades installing this component as part of a complete exit hardware assembly. The XDT-12 is used in commercial door hardware systems where timed door release is required by building code or security design. Typical installations include office buildings, healthcare facilities, schools, and other occupancies that require delayed egress functionality on emergency exit doors. The module integrates into the low-voltage control circuit of the exit device rather than the high-voltage door power supply. Key Features 12-volt DC operating voltage for compatibility with standard low-voltage control circuits UL listed for use in code-compliant exit device installations Designed for delayed egress door hardware applications in commercial settings Single-unit packaging for direct replacement or new installation Compatibility Designed as an OEM-style replacement or add-on time delay module for 12-volt DC exit device control systems.
