Class A-B Two-Wire Module FX-2WIRE
Kidde intelligent modules are engineered to deliver high-performance features, superb reliability ⭐
✅ and unbeatable quality. control of ancillary equipment, to enhanced signaling functionality, these products add flexibility and powerful options to Kidde intelligent systems
Designed expressly for small buildings, Kidde modules are addressable devices that are uniquely identified on the system by means of familiar rotary switches. Once registered, they share data and status information that determines how the system behaves and how connected devices interact with one another.
- Unique to Kidde modules is ground fault detection so precise that it actually pinpoints the specific module where the wiring problem has occurred. This saves hours of troubleshooting and wire tracing. And only Kidde provides this important feature!
- The Kidde family of intelligent modules also offers contractors and installers simple setup and installation, while delivering options that take full advantage of intelligent fire alarm processing. With a microprocessor in each device, intelligence is distributed throughout the system so that command decisions are made instantly at the individual module, rather than bottlenecking at the control panel.
- This not only speeds event processing, it also makes a more robust and reliable system – so robust, in fact, that when upgrading a conventional panel to a Kidde intelligent system, you can usually use existing wiring – no twisted or shielded cable required!
Standard Features
• Class A-B Two-Wire Module
- Acts as an interface between conventional two-wire smoke detectors and the Kidde control panel.
• Analog Class A Single Input Module
- Used to connect a normally open, alarm, supervisory, or monitor type dry contact initiating device circuit to the Kidde control panel.
• Analog Dual Input Module
- Connects two normally open, alarm, supervisory, or monitor type dry contact initiating device circuits to the Kidde control panel.
• Analog Dual Input Waterflow, Supervisory Module
- Used to connect normally open waterflow alarm and supervisory initiating device circuits to the Kidde control panel. For Class B circuit operation.
• Analog SLC Fault Isolator Module
- Protects a Class A SLC total collapse due to wire-to-wire short circuits.
• Analog NAC Module
- Connects a supervised output circuit to a signal riser.
• Analog Contact Relay Module
- Provides one Form C dry relay contact and can be configured to provide polarity reversal of its output.
• Analog Single Input Mini Module
- Connects a normally open, alarm, supervisory, or monitor type dry contact initiating device circuit (IDC) to the Kidde control panel. For Class B circuit operation.

Class A-B Two-Wire Module FX-2WIRE
- The FX-2WIRE module interfaces between conventional two-wire smoke detectors and the Kidde control panel. It monitors the circuit and smoke detectors, and signals the control panel of any trouble or alarm conditions. The module also regulates and supervises the 24 VDC input power.
- The FX-2WIRE is configured to operate as a two-wire alarm device that does not require alarm verification. It can be set for two-wire alarm verified operation through front panel programming or the configuration utility. When using the alarm verification feature of the control panel, do not mix normally open contact initiating devices with two-wire conventional smoke detectors.
- This module recognizes the CleanMe signal detectors that support this feature.
- The device address is set using the two rotary switches located on the front of the module. One device address is required.
