The VESDA VSP-964-04 is the MK4 spare smoke detection chamber for VESDA-E VEU, VEP, VEP-1P and VES aspirating smoke detectors. Service technicians use it to restore a detector in the field without replacing the whole unit, which keeps downtime short in data centers, clean rooms and other high-value spaces. Matching the chamber revision to the detector generation matters, so check the detector serial number before ordering.
