Product information for RCS Audio-Systems ESU-002 A:

The ESU-002A is a compact and reliable emergency switching unit designed to perform two independent switching functions during emergency scenarios. In the event of a priority signal (e.g., a fire alarm), it can switch 100V speaker lines from a tenant's local audio program to the building's central emergency system and simultaneously disconnect two separate 230V power supplies.

This functionality is crucial in multi-tenant buildings where private audio systems must be overridden to allow alarm announcements from the main system. The unit features a priority relay module capable of handling both 100V audio signals and high-voltage mains power (up to 250 V AC).

The ESU-002A is easy to install thanks to accessible terminal blocks and defined wire stripping lengths. Housed in a durable enclosure rated IP 66, it is suitable for both indoor and harsh outdoor environments.
