6.6 Connecting the Air Sampling Pipe
The air inlet port is designed to fit a standard pipe of 25mm (1in) OD. A tapering of the air inlet port prevents the
pipe from being inserted beyond 15mm (5/8in).
Note: Where it is common practice to use ¾ inch pipe which has a 1 1/16 inch OD, a suitable adaptor
should be used to connect the pipe to the inlet manifold. Such an adaptor is supplied with the
VESDA VLC in the appropriate territories.
a. De-burr and square off the end of the sampling air pipe. Ensure the pipe is free from debris.
b. Remove the plugs from the inlet and exhaust ports.
c. Insert the pipe into the inlet port ensuring a firm fit. DO NOT glue this connection.
d. Pipe the exhaust when necessary.
Caution: DO NOT GLUE THE AIR INLET AND EXHAUST PIPE CONNECTION – THIS ACTION
WILL VOID YOUR WARRANTY.
Glued connections makes disconnecting the air sampling pipe from the VESDA VLC for
maintenance extremely difficult and will result in damage to the equipment.
Attention : NE PAS COLLER LES TUBES D'ENTRÉE D'AIR ET DE REFOULEMENT AU NIVEAU DU
DETECTEUR.
Un raccordement collé rendra indémontable le tube de prélèvement d'air du VLC et rendra les
opérations de maintenance extrêmement difficile, de plus, il pourra endommager l’appareil.
6.7 Cabling Using Glands and Conduits
6.7.1 Using Glands
a. If using cable glands, use the correct gland size to fit the 25mm (1in) Ø cable entry hole.
b. Run the wires through the glands and into the VESDA VLC enclosure. Use your local codes and
electrical standards for cabling.
