Combination Waterflow/Supervisory Zone

A combination Waterflow/Supervisory circuit allows an FACP to distinguish between an Alarm switch (waterflow device) and a Supervisory switch (tamper) installed on the same circuit. The following figure illustrates the wiring of Zone 2 as a Style B (Class

B)Waterflow/Supervisory circuit. Note that only Zone 1 on the MS-2 and Zone 2 on the MS-4 can be configured in this manner.

Requirements for the Combination Waterflow/Supervisory circuit are as follows:

The Waterflow Alarm Switch(es) must connect to the FACP Initiating Device Circuit before the In-Line Resistor as shown in Figure 2.5

The Waterflow Supervisory Switch(es) must connect to the FACP Initiating Device Circuit after the In-Line Resistor as shown in Figure 2.5

Program the FACP Initiating Device Circuit #1 on the MS-2 or Circuit #2 on the MS-4 as a Combination circuit by placing SW1 DIP switch 8 to the ON position as described in "SW1 DIP Switch Settings" on page 34

Waterflow Alarm Switch activation causes the panel to latch into alarm until the alarm condition is cleared and the FACP is reset

Supervisory Switch activation causes the panel to track the supervisory condition, that is, the panel will clear when the supervisory condition is cleared (if FACP is programmed for Autoresettable Supervisory)
