6 Installation
6.1 Check Procedure Before Installation
a. Do not install your VESDA VLC if there are any signs of shipping damage to the product. Inform your
distributor if there is any damage.
b. Check the model of the VESDA VLC is correct as per the design specifications for the site. Refer to the
model number located on the bottom of the detector enclosure.
c. Identify the location where the detector is to be mounted. The VESDA VLC can be mounted on a wall or a
suitable secure surface. There are two allowable mounting positions (see Figure 6-1) for the VESDA
VLC:
l
Mounting the device with the air inlet pipe on the top of the box and with the air exhaust pipe at the
bottom. (Normal Orientation)
l
Mounting the device with the air inlet pipe at the bottom of the box and with the air exhaust pipe on
the top. (Inverted Orientation)
d. Verify that the selected mounting location is suitable to fit the detector by test fitting the VESDA VLC
onto the actual mounting position. Ensure there is 150mm (6in) of clear space around the air inlet pipe and
cable entry points to allow for pipe and conduit entry.
e. Verify that the cable entry points and the sampling air pipes are at the correct locations.
f. Determine the type of fasteners required to attach the mounting bracket onto the mounting surface. The
size of the screw holes on the mounting plate is 8mm (1/3in).
