The AFC-50 is an analog/addressable fire alarm system that can release 50 addresses in total. Utilizing multi-point SLC modules, the system is able to handle more capacity. The exclusive Potter protocol, which uses a full range of sensors and modules, is used by the control panel. Each SLC allows for a maximum impedance of 50 ohms and can utilize any wire that complies with the National Electrical Code. It can be made up of any combination of smoke detectors, heat detectors, or modules (NEC). The AFC-50 features two Notification Appliance Circuits (NACs), two Input/Output (I/O) circuits, and a 5 Amp power source. The I/Os are individually rated for 1 Amp, whereas the NACs are each rated for 3 Amps. Each output has a power restriction and is regulated. Additionally, each output can be individually programmed and can be set to produce a steady signal, synchronize strobes, have constant power, power door holders, or release. Gentex, AMSECO, System Sensor, Cooper/Wheelock, and the proprietary Quadrasync are the strobe synchronization companies. Each output may have a distinct brand, and all strobes will flash simultaneously.
