Section 3 – Installing the FNP-1127-SLC
3.1 Overview of the FNP-1127-SLC
The FireNET Plus control panel is provided with one SLC Loop. An additional SLC Loop may be added
through the use of a FNP-1127-SLC loop expander board.
The main control unit has terminations for connecting the first SLC loop. The connections for the second
loop are located on the FNP-1127-SLC expander board.
3.1.1 Installation of the FNP-1127-SLC
1. To install the additional SLC Loop, the control panel must have its AC and battery power
removed.
Do not attempt to install the SLC expander board while the FireNET Plus panel is
powered!
2. Remove the screw on the front display panel and open the panel to the left, exposing the back of
the circuit board.
3. The circuit board containing the additional loop circuit is supplied in a static dissipative bag and
should remain in this bag until it is to be installed.
NOTE:
As with all electronic components, this circuit board is very sensitive and can be easily
damaged by electrostatic discharge.
4. The loop board mounts on the upper left hand side of the rear of the circuit board. Install the
mounting standoffs to the main board then attach the expander board using the M3 screws and
fiber washers.

5. After ensuring that the new circuit board is properly installed and making good contact with its
connectors close the front display panel and secure with the screw.
6. Connect the SLC loop wiring and then re-apply power to the control panel. Note that class B SLC
circuits require the installation of the supplied 0 ohm jumpers (HA part # 0400-01025)
After the new SLC devices have been installed and connected, they may be automatically detected using
the auto learn feature from the menu on the control panel.
Please see the FireNET Plus Installation and Operation manual for more details on panel configuration
and programming (HA part # 1700-10840)
