Input Circuits
Combination Waterflow/Supervisory
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. Any cir-
cuit can be programmed as a Combo Type zone. The following figure illustrates the wiring of Zone
2 as a Style B (Class B) Waterflow/Supervisory circuit.
Supervisory Switch
(tamper)
In-Line-Resistor
1.2 KΩ, ½ watt resistor P/N: 75579
Alarm Switch
(waterflow)
Requirements for the Combination Waterflow/Supervisory circuit are as follows:
This circuit is only intended for one Waterflow and one Supervisory device.

The Waterflow Alarm Switch must connect to the FACP Initiating Device Circuit before the

In-Line Resistor as shown in Figure 2.6.
The Supervisory Switch must connect to the FACP Initiating Device Circuit after the In-

Line Resistor as shown in Figure 2.6.
Program the FACP Initiating Device Circuit as a Combination circuit as described in "Input

Zones" on page 54. Note that since a Waterflow Supervisory Switch in included in a
Combination circuit, the waterflow delay must be taken into consideration. Refer to
"Waterflow Delay" on page 66.
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 latch into supervisory condition if the

Combo type code is selected or track (the panel will clear when the supervisory condtion is
cleared) if the Combo Autoresettable Supervisory type code is selected.
