SLA-127P Single Loop Intelligent Adder Card

The Single Loop Adder provides an additional 127 addressable points to the base 127 addressable points standard with the PFC-

9000. The addressable loop is fully analog/addressable and can be any combination of sensors and modules. Only one loop adder

module, either the SLA-127P or the DLA-254P (Dual Loop Intelligent Adder Card) can be installed to a PFC-9000 system.
The SLA-127P 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 SLA-127P 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 SLA-127P is Loop 2 in the

Configuration Software.
The P2 ribbon cable from the adder card 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 SLA 127P 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 SLA-127P 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.
