Vesda VSP-956-04 — VESDA-E flow sensor manifold, the service replacement air path and flow sensing assembly for GA4 generation VEU, VEP and VEP-1P aspirating smoke detectors.
The manifold carries sampled air from the detector inlet past the flow sensors, so it is what gets replaced when flow sensing misreads or the air path is fouled. Xtralis splits VESDA-E spares by hardware generation and the number carries it: -04 marks a GA4 part. Generation comes off the detector serial number, not the model name.
- Flow sensor manifold for VESDA-E VEU, VEP and VEP-1P detectors
- GA4 generation only; GA4 detectors carry serial numbers beginning 109
- GA3 detectors, serial numbers beginning 97, 106, 107 or 110, and GA2 detectors beginning 96, take the unsuffixed VSP-956
- Listed as a spare beside the VSP-964-04 chamber, VSP-963 aspirator and VSP-965 sampling module
Two neighbours are easy to order by mistake. VSP-955-04 is the GA4 scanner manifold and belongs to the VES, the one VESDA-E model this part does not fit. VSP-956 without the suffix is the same assembly for the earlier generation. VSP-964-04 is the smoke detection chamber in the same detector.
