Fan Safety Alram Circuit are simply devices that combine a common relay-logic function into a small, easy-to-install, and less expensive form.
A master relay will open if any one of the normally-closed (N/C) inputs open. There are six, four, or two inputs depending on the model chosen. LED status of all inputs, the master relay, and power input is provided. Bypass of un-used inputs is also provided. The RIBMNLB series is provided with mounting track for mounting in user-provided electrical enclosures. The master relay has two general-purpose outputs: both can be jumper selected at 24 V (sourced from input) or dry contact. The most common application is an Air Handling Unit (AHU) fan-safety-shutdown where the master relay is used to shut down the fan. Contact closure outputs are provided so that a DDC controller can determine the cause of a shutdown.
