Kidde FX-SLC2 Expansion Module, 250-Device Loops, 500 Devices Total

Scale your fire alarm and security coverage without replacing the control panel. The Kidde Commercial FX-SLC2 expansion module is a control panel module designed to add two supervised SLC loops to UTC Kidde FX systems, expanding capacity to 500 devices total (two 250-device loops).
