The IFP-2100 is an addressable 2100 point fire alarm control panel. The basic IFP-2100 panel contains one built in signalling line circuit (SLC), which can support 159 System Sensor IDP/SK sensors and 159 IDP/SK modules or 127 Hochiki SD devices per loop. Additional SLC loops can be added using the model 6815 SLC expander for IDP/SK devices to increase the overall point capacity to 2100 or model 5815XL for SD devices to increase the overall point capacity to a maximum to 2032 points per panel. IFP-2100 has the interconnection capability for up to 32 panels. The system has two modes of operation, multiple panels covering one larger building, or multiple independent buildings. The RFP-2100 (red) or RFP-2100B (black) can be used in a networked system where at least one IFP-2100 is in the system. It is the same as the IFP-2100 without the display.
