DLA-254P Dual Loop Intelligent Adder Card
The Dual Loop Adder provides two additional loops with 127 addressable points per loop in addition to the base 127 addressable
points standard with the PFC-9000. The addressable loops are fully analog/addressable and can be any combination of sensors
and modules. Only one loop adder, either a SLA-127P or DLA-254P can be installed in a PFC-9000.
The DLA-254P mounts in the far right adder location in the PFC-9000 and connects directly to the main fire alarm board. The
stand-offs are factory installed in the chassis and the DLA-254P screws directly to the stand-offs. Power down the system and
connect the plugs to the main fire alarm panel before fastening the adder card to the panel chassis. The DLA-254P is Loop 2 and
Loop 3 in the Configuration Software.
The ribbon cable from the panel is connected to P5 on the main fire alarm panel. The yellow loop expansion sticker will have to
be removed before connecting the loop adder to the main board. If additional adder cards will be installed, plug the long ribbon
cable that comes with the DLA into P6 on the PFC-9000 board. This cable will connect to P2 on the next adder card to the left.
The loop adder receives power from the main fire alarm control panel. If just a DLA-254P is added the cord will plug into the
main board (P8). If Adder Modules are installed, a longer cable is used to connect P3 of the furthest left module to P8 of the 9000
chassis. P4 of the adder module next to the DLA-254P then connects to P1 of the Loop Adder.
All of the loops must be wired either Class A or Class B, the mixing of wire combination is not possible. If shielded cable is used
as the loop conductor, only wire one leg to the “Shield” terminal on the loop adder board. As with the main panel, the terminals
are marked for Class A and Class B wiring.
