5.5 MDF-300 Wiring Diagrams
Following is a wiring diagrams that depict NFPA Style B (Class B) Initiating Device Circuits
(IDCs) using MDF-300 Dual Monitor Modules.
5.5.1 Wiring a NFPA Style B IDC with an MDF-300
Connect the SLC wiring to the module terminals 1 (–) and 2 (+).
Use the rotary switches on the module to set it to the SLC address. Each dual module takes two
addresses on the SLC. Circuit ‘L’ corresponds to the address set on the rotary switches, which will
be an even number. Circuit ‘H’ will automatically respond to the next higher address, which will be
an odd number. Use caution to avoid duplicate addressing of modules on the system. Refer to “Set-
ting an SLC address for a Single Point Module” on page 32.
Each IDC (H & L) is power limited to 230 microamperes @ 24 VDC.
The figure below shows typical wiring for a supervised and power-limited NFPA Style B IDC
using an MDF-300-10 module.
• Refer to the Device Compatibility Document for compatible smoke detectors.
• See “Power Considerations” on page 61 for information on supervising 24 VDC power.
