Total Access 3000/3010 shelf. These are marked ACO, RMT and AUX2 (if AUX1 is
not being used for the fan alarm it may also be used for other inputs). Each functions
in an identical manner to the fan alarm. Terminal B supplies a -48 VDC source.
Terminal A expects -48 VDC if an alarm condition exists on the alarmed equipment.
1.
Connect an external alarm input to the shelf:
A.Using a #1 Phillips-head screwdriver, remove the long, thin plastic guard if
it is not already off from a previous procedure.
B.Choose an alarm header set from the EXT INPUTS block, P22/P20, on the
middle bottom of the Total Access 3000/3010 backplane.
C.Using standard Telco cross-connect wire, determine and cut the length
required to reach from the alarmed piece of equipment to the header you
chose in step B.
D.Allow length for 1 to 2 inches of stripped wire for wire wrap, and neat
routing out from the Total Access 3000/3010 shelf.
E.Using wire strippers, strip 1 to 2 inches from both ends of the wire.
NOTE
Omit the following step, F., if the alarmed piece of equipment has its own
source of -48 VDC and doesn’t need the -48 VDC feed from the Total
Access 3000/3010 shelf. The Total Access 3000/3010 shelf expects to see
-48 VDC on pin A of the alarm pair when an alarm condition exists.
F.Using a wire-wrap gun, wire wrap one wire to the B pin of the Total Access
3000/3010 AUX1 header (P22/P20), and the other end to the alarmed unit
alarm terminal marked “B.”
G.Wire wrap one end of the second wire to the A pin of the Total Access 3000/
3010 alarm header (P22/P20) and the other end to the appropriate equipment
alarm terminal.
H.Using a #1 Phillips-head screwdriver, replace the long thin plastic guard
using the two screws provided.
NOTE
Check with the equipment manufacturer for exact alarm markings.
NOTE
If this Total Access 3000/3010 shelf will be daisy chained with a number of
other shelves using the RS-485 bus (P2/P21), do not replace the guard at this
time. The guard will be replaced after the RS-485 interconnection,
accomplished next in Section 1.13.1 of this Installation section.
