Combination Fiber and Wire Style 4
Connection - Application 8 (See Figure 10)
The RCM-1 can support a combination of fiber
optics and wire which can be used to connect
to other systems which require global paging
capability.

Notes:
1. Use 18AWG minimum wire.
2. Limit the maximum resistance of loop total from the first RCM to
the last RCM to 100 ohms. Maximum line capacitance = 1µF.
3. The wiring is power limited to NFPA 70 per NEC 760.
4. Maximum voltage is 1.5V RMS.
5. Maximum current is 50mA.
6. Refer to Figure 12 for proper EOLR placement.
7. Refer to Wiring Specification for MXL, MXL-IQ and MXLV
Systems, P/N 315-092772 revision 6 or higher, for additional
wiring information.
8. Positive and negative ground fault detected at <50K ohms for
terminals 1-6 and 17-20.
