sensors The CMC III CAN bus sensor supports the connection of selected sensors from the CMC-TC system to the new CMC III, allowing old applications to be upgraded with the CMC III Processing Unit / Compact. As well as the two CAN bus connections, the unit also has another connection for one of the CMC-TC sensors. In this way, the unit func- tions as an interface between the CMC-TC sensor and the new processing unit, and adapts the sensor data to the CAN bus proto- col.
The following CMC-TC access sensors may connected to the CMC III CAN bus sensor: – 1 x temperature sensor – 1 x analog input 4 – 20 mA – 5 x access sensors in series – 1 x airflow sensor – 1 x smoke detector – 1 x motion detector – 1 x digital input – 1 x digital relay output – 1 x voltage monitor – 1 x 48 V voltage sensor – 1 x leak sensor – 1 x leak sensor, 15 m sensors – 1 x door control unit (two connections) – 1 x DET-AC Plus extinguisher system (three connections)
– 1 x DET-AC Plus early fire detection system (three connections)
