VESDA VSP-877 Flush-Mount Sampling Point
The VESDA VSP-877 is a flush-mount sampling point for Xtralis aspirating pipe networks, used in place of a conical point where a capillary run ends in a finished ceiling. A snap-fit fascia covers two locking screws that pull a pair of wing-locks against the back of the panel, so the whole fitting installs from below; this makes it suitable for fixed ceilings without void access.

Product details
The VESDA VSP-877 is a flush-mount sampling point for Xtralis aspirating pipe networks, used in place of a conical point where a capillary run ends in a finished ceiling. A snap-fit fascia covers two locking screws that pull a pair of wing-locks against the back of the panel, so the whole fitting installs from below; this makes it suitable for fixed ceilings without void access.
The wing-lock height adjusts to the panel thickness, the fascia lifts off for cleaning, and the molding carries DO NOT PAINT marking.
Key features
- Push-fit capillary connection for 6, 8 and 10 mm and 1/2" tube

Ordering note
The VSP-877-B and VSP-877-G are the same sampling point in black and grey. The VSP-878 is the 1/2" push-in connect adaptor kit, not a sampling point. Xtralis does not publish a per-box quantity for this item.
