Eaton STH-2MS5-R Wheelock STH Speaker Strobe

For facilities that demand reliable, high-visibility emergency notification, the Eaton Wheelock STH speaker strobe combines powerful audio and visual signaling in a single, code-compliant unit. The Eaton STH-2MS-R speaker strobe delivers up to 102 dB output and includes a UL-listed strobe and supervised horn mounted in a prefabricated 10" x 10" x 6" steel enclosure, making it ideal for security, fire alarm, and monitoring applications. With a wide 10.5–31V DC operating range and omni-directional sound, the STH unit ensures consistent alerts across large rooms and high ambient noise areas. Preassembled components and single-pair audio wiring reduce installation time and labor costs, while UL 1480/1638 and NFPA compliance simplify inspections and system approvals.
