Heavy duty relay unit for conventional fire systems

Eaton's Heavy Duty Relay unit interfaces conventional fire alarm systems with heavy loads such as door release units or plant shut down equipment.

Simple to fix and install, its neat unobtrusive design makes it suitable for installing in small areas with most building users not even noticing its presence.

Powered by 24V dc external supply, the relay unit is provided with 2 separate sets of changeover contacts. It also features a front mounted status LED which illuminates when the relay is energised.
