120 VAC supply line is a Class I, energy-limited circuit. A
customer-supplied junction box or duplex clamp connector
(strain relief) should be used to split supply line from dry
contact circuit.

fault condition has cleared. During those situations when the
fault condition occurs and corrects itself prior to pushing the
acknowledge button, the horn and red LED will activate and
clear to match the fault condition. However, the yellow LED
will remain lit to indicate that the fault condition had previ­ously taken place. Pressing the acknowledge button will
clear the yellow LED.

For low level alarms, use Model RA431B1. A normal condi­tion would be when the liquid is on the probes. A fault
condition occurs when the liquid falls off the probes. The
operation would be as described above.

Test Button: Pushing the test button allows you to test the
alarm panel circuitry. On pushing the test button, the horn
will activate and the red and yellow LED will light. On
releasing the test button, the horn and red LED will deacti-
vate. The yellow LED will remain lit until the acknowledg-

ment button is pressed.

Dry Contact Operation: The green LED will light when power

is applied to the unit. When the remote contact switches state
(fault condition), the horn will activate and the red and yellow
LEDs will light. On pressing the acknowledge push-button,
the horn will silence and the yellow LED will clear. The red
LED will remain lit as long as the fault condition is present. On
correcting the fault condition, the red LED will automatically
clear.

During those situations when the fault condition occurs and
corrects itself prior to pushing the acknowledge button, the
horn and red LED will automatically activate and clear,
matching the fault condition. However, the yellow LED will
remain lit to indicate that the fault condition had previously
taken place. Pressing the acknowledge button will clear the

yellow LED.

Liquid Level - Conductance Probe Operation: For high level

alarms, model RA431A1 should be used. When power is
applied to the unit, the green LED will light. A normal condi­tion would be when the liquid is below the probes. When the
liquid touches the probes, the horn, red and yellow LEDs will
activate. On pressing the acknowledge button, the horn and

yellow LED will clear. The red LED will remain lit until the
