Overview: Gen 5 Sensors Cabling Matrix
The Sensor Cabling Matrix table provides an overview of the cables needed to connect a Gen 5 sensor to the Control Unit. The table is categorized based on the type of Gen 5 sensor and Control Unit model.
The maximum cable length between an Enlighted SU-5 sensor (SU-5E or SU-5S) and a CU-4E/CU-4D control unit can be a 300’ CAT5E cable. Multiple cables from different sensors going to different CUs can share the same raceway or cable tray without signal degradation or cross-talk. Maintain the separation of circuits from class 1 wiring per the requirements of the AHJ.
Note: All Enlighted cables are plenum-rated as indicated by the CMP (Communications Multipurpose Plenum), 600 VAC, #24 AWG CAT 3 cables, and UL numbers are indicated on the cable.
