A Combination Waterflow/Supervisory Valve Monitor circuit allows an FACP to
distinguish between a Waterflow Alarm Switch and a Waterflow Supervisory Switch
installed on the same Monitor Module. Figure 5-23 shows an NFPA Style B Initiating
Device Circuit (IDC) that meets requirements for a Combination Waterflow/
Supervisory Valve Monitor circuit.

The following list includes requirements for the Combination Waterflow/Supervisory
Valve Monitor circuit. (Refer to the AFP-300/AFP-400 Programming Manual for
details on programming a Monitor Module.)
1. The Waterflow Alarm Switch must connect to the Monitor Module initiating input
before the In Line Resistor.
2. The Waterflow Supervisory Switch must connect to the Monitor Module initiating
circuit after the In Line Resistor.
3. The Combination Waterflow/Supervisory Valve Monitor circuit only functions as a
Style B (class B) circuit.
4. While a Supervisory Signal is tracking, Waterflow Alarms latch until reset.
5. Program the Monitor Module for type code SPRINKLR SYS or COMB.
MONITOR (Figure 5-23).
6. Program the Monitor Module for the desired Control-by-Event (CBE).
7. A Supervisory signal does not affect the outputs listed in the Monitor Module CBE
(Figure 5-23).
8. Appendix B: Wire Requirements, lists the type of wire required for an IDC.
Figure 5-23 shows a sample program screen for a waterflow application:
