26 Hardware Installation—IFC-200 Hardware Installation Procedures

Do not mix fire alarm initiating, supervisory, or security devices on the

same module IDC. No external ELR is required for Style D wiring. See

Figure 21.

1. Connect the Style D IDC to M502MJ terminals 6 (-) and 9 (-),

then 7 (+) and 8 (+).

2. Do not loop wire under terminals. Break wire run to provide

supervision of connections.

3. Power to the M502MJ must be externally switched to reset the

detectors. An M510CJ control module can be used to switch power

from a standard UL Listed power supply if the IFC-200 power supply,

available on TB1-5 and TB1-6, is not used.
