5.7.2 Wiring a NFPA Class A IDC with an MMF-302-6
Connect the SLC wiring to the module terminals T0 as shown below.
Use the rotary switches on the module to set it to the SLC addresses. Each module takes three alternating addresses on the SLC. The
remaining module points are automatically assigned to the next two higher addresses. (Example: 28, 30 and 32). Refer to “Setting an
SLC address for a Multi-Point Module” on page 33.
DO NOT
set the lowest address above 150 (41 for the MS-9050UD or ES-50X, 90 for the MS-9200, MS-9200UD, MS-9200UDLS, or
ES-200X), as the other module points will be assigned to nonexistent addresses.
The figure below shows typical wiring for a supervised and power-limited NFPA Class A IDC using an MMF-302-6 module.
•
Refer to the
Device Compatibility Document
for compatible smoke detectors.
•
24 VDC power must be provided from a UL listed power supply for fire protection use. This power is inherently supervised by the
module.
•
See “Power Considerations” on page 63 for information on 24 VDC power.
