Wiring
1. Terminal strip capable of handling 12-22 gauge stranded wire
14-22 gage solid wire.
2. Intrinsically safe wiring must be kept separate from nonintrinsically safe wiring.
3. Wire the sensor(s) to the TA-731XX as shown in in the wiring
diagram on the reverse side. (Diagram D-2)
4. An approved seal should be used at the point where theintrinsically safe control circuit wiring enters the hazardousarea.

Notes
1. All intrinsically safe wiring must be installed in accordance witharticle 504 of the National Electrical Code, publication ANSI/NFPA 70.
2. Grounding
Grounding:: To maintain intrinsic safety, the terminal marked“GND” on the AC supply terminal should be connected to theearth ground buss of the AC power supply feeder. Metal
conduit must be used to provide a redundant system ground.
The resistance between the system ground terminals (at thecontrol) and the earth ground buss must be less than 1 ohm.
3. The maximum total length of intrinsically safe wiring extending
from terminal S1 shall not exceed 5,000 feet. (This excludesground)
4. The intrinsically safe terminals of the TA731XX can beconnected to any non-energy storing switch device, such as alimit or float type switch or any Warrick electrode fitting
assembly.
5. For additional guidance on “Hazardous Location Installation”
and “Intrinsically Safe Devices”, consult ANSI/ISA standard RP
12-6 or NEC articles 500 through 516.

Installation
1. Mount the TA-731XX panel on wall or other solid object
with 4 (four) #8 or appropriately sized screws.
2. Incoming Power: 3-wire 120 VAC supply, Class Icircuit.

Dry Contact Operation
Operation:: The green LED will light when power isapplied to the unit. When either sensor contact switches state(faultcondition), the horn will activate and the appropriate red andyellow LED’s will light. On pressing the acknowledge pushbutton,LED’s
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 andcorrects itself prior to pushing the acknowledge button, the hornand red LED will automatically activate and clear, matching the faultcondition. However, the yellow LED will remain lit to indicate thatthe fault condition had previously taken place. Pressing theacknowledge button will clear the yellow LED.
Test Button
Pushing the test button allows you to test the alarm panel
circuitry. On pushing the test button, the horn will activate, the redand yellow LED’s will light and the auxiliary relay will activate. OnLED’s
releasing the test button, the horn, red LED and auxiliary relay willdeactivate. The yellow LED will remain lit until the acknowledge
button is pressed.

Auxiliary Relay Operation
Model TA-731X0 contains an auxiliary relay for remoteindication of a fault condition. The contact configuration
shown in Diagram D-2
D-2, shows the position of the contacts
in the non-fault condition. The relay can be field set toeither a “cut-off” mode or “alarm” mode. In “cut-off” mode,
only channel 1 will activate the auxiliary relay. The relay will
mimic the red LED or fault condition. The relay will activate
on fault condition, changing the state of the contacts. To
deactivate the relay, you must clear the fault condition.
Pressing the acknowledge button will not deactivate therelay. In “alarm” mode, the relay will mimic the horn. Therelay will activate on fault condition changing the state ofthe contacts. To deactivate the relay, either press theacknowledge button or clear the fault condition. Onmodels TA-731X1 and TA-732X2, the auxiliary relay ispreset at the Factory and is not field adjustable.
