The ECC-RPU is an optional Remote Page Unit that is com- patible with the ECC-50/100(E) Emergency Command Center for fire protection applications. It is part of the family of external remote consoles that allows for extending the ECC-50/100(E) display and control to remote locations within a building. It is housed in a cabinet with a keyed or an optional thumb lock to limit access to qualified personnel. The ECC-RPU includes a built-in microphone and 8 selection buttons that can be pushed to activate the system remotely. ALL CALL paging can be broadcast over the speaker circuits by depressing the microphone's push-to talk button. As an added benefit, the 9th button on the RPU can be used to acti- vate an MMF-300 monitor module that may be installed inside the ECC-RPU cabinet to be used for applications such as HVAC shutdown. The ECC-RPU requires an external data bus connection, an external audio riser connection, and an exter- nal operator interface power connection (24 Volts DC) from the ECC-50/100 main console.
