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 17-20.
Typical Style 7 Connections - Application 3
(See Figure 6)
The RCM-1 provides a Style 7 output which can
be used to connect to other systems which
require global paging capability.
