Kidde brand conventional fire alarm systems consist of 5 and 10 zone fire alarm control panels (FACP), an optional integrated upload/download DACT (dialer), intelligent/analog type detector features, serial annunciator modules, and serial remote relay modules. All FACPs and components are listed to the 9th edition of the ANSI/UL 864 standard and CSFM/FDNY approved. These systems incorporate features designed to simplify installation, operation and maintenance, including front panel programming, one person walk testing, and selectable IDC and NAC types. In addition, when used with CleanMe® compatible smoke detectors, these control panels provide intelligent type features such as remote maintenance alert and automatic drift compensation that significantly reduce the chance of a false alarm and simplify maintenance calls. Kidde systems are powerful enough to meet the demands of today's life safety installations while leaving plenty of room to grow in the future. They support class A operation by combining pairs of on-board IDCs or NACs to provide the necessary class A circuits. For example, the FX-10RD comes factory set to support 10 class B IDCs and 4 NACs. But it can be field configured to provide 5 class A IDCs (no class B IDC's) and 2 class A NACs or any other combination of circuits that fall within the circuit-pairing parameters.
