Mounting
The ALC Outdoor LF BUS Beacon with Loop enclosure is comprised of a base, PCB tray with spacers, and a cover. The enclosure comes with
cable gland to seal the cables to the enclosure.
1.
To open the enclosure, use a flat head screwdriver to remove
the screws in the corners and open.
2.
To remove the PCB, tuck in the spacer wing locks with either a
finger nail or a hexagon socket and lift PCB.
3.
Drill holes to match mounting screws, and insert screws to
mount.
4.
Use attached black plastic caps to seal mounting holes.
5.
Insert and connect the loop (if using) and if required, synch and
BUS cables (see
Connecting the Loop
).
6.
Place PCB back into place (fit spacers through the respective
holes), and push down until the spacer wing lock fasten the
PCB. Make sure to place PCB so the terminals face inward.
Note:
To remove PCB, use attached, 6mm dowel to tuck in the
spacer wing lock, and pull up PCB.
7.
Place front cover back into place and fasten the cover screws.
Connecting the Loop
1.
Loosen two Cable gland nut and remove caps.
2.
Insert each end of the loop through the screw cap, cable gland,
and through the cable hole.
3.
Release the terminals to which you want to connect the loop
conductors, and connect the conductors.
Make sure each conductor is connected by an offset of one
terminal. For example: If you connect one end of the red
conductor to terminal P2, connected the other end to terminal P1.
Connect the other conductors in the same fashion, and that the
order within the conductors is identical on each side.
4.
Make sure the cable gland is positioned, and tighten the cable
gland nut.
5.
Tighten the screw cap to the cable gland to seal the cable to the
gland.
6.
To connect the loop to the ALC PCB, connect two cables to the
free sides of the terminals to which the loop is connected on only
one side. On the PCB end, connect the cables to terminal block
J7 (order in the J7 terminal is not important).
Note:
Insert a BUS or I/O cable (or any other cable) with the glands
and screw caps in the same manner as the loop cable, and connect to
the appropriate PCB terminals.
Note:
When you open the enclosure to connect/replace/remove a
cable, you trigger the tamper and the Tamper alert.
