Wiring Instructions
Wire used for this installation must have a temperature rating of at least 90°C. be either 14 or
16 AWG, and be color coded. Splicing alarm power with TLS Console power will cause
improper operation of the monitor.
Wiring Overfill Alarm with Acknowledgment Switch
1. Pull two wires from the switch to the Overfill Alarm.
2. Pull two wires for line and neutral from the switch to the power panel.
3. Pull one wire from the switch to the TLS Console for connection to the alarm relay.
4. Pull one wire for line from the alarm relay in the TLS Console to the power panel.
5. Turn power Off and connect wiring according to the wiring diagram in Figure 3 and Table 1.

Wiring Overfill Alarm without Acknowledgment Switch
1. Pull one wire for neutral from the Overfill Alarm to the power panel.
2. Pull one wire from the Overfill Alarm to the console for connection to the alarm relay.
3. Pull one wire for line from the alarm relay in the console to the power panel.
4. Turn power Off and connect wiring according to the wiring diagram in Figure 4 and Table 1.

Enclosure Grounding
There are two separate methods for grounding the Overfill Alarm. Ensure that the ground connection is made in
accordance with all local codes.
If using a properly grounded rigid metal conduit or equivalent to enclose the external wiring for the Overfill Alarm,
the ground hub that terminates the conduit provides an adequate grounding provision for the Overfill Alarm.
If using a ground wire within the conduit, terminate the ground wire on the grounding stud located in the bottom of
the enclosure. Ensure that a star washer is between the enclosure and the lug attached to the ground wire and
that the lug is secured in place by the included KEPS nut (see Figure 5).

Setup and Test
Setting Overfill Alarm Horn Delay Time
1. Loosen the four screws that secure the Overfill Alarm cover clamps to the case. Slide the clamps away from
the retaining lip on the door. Open the door.
2. Locate the Horn Time Delay Relay (see Figure 3).
3. Adjust the time the horn remains On from 0 to 60 seconds by turning the knob on the relay to the desired
setting.
4. Close the door and tighten the four cover screws.
Testing the Overfill Alarm with the Acknowledgment Switch
Turn On power to the Overfill Alarm and Acknowledgment Switch. Depress and hold in the TEST Button on the
right side of the switch. The Overfill Alarm horn will sound immediately, and the Overfill Alarm’s red light will start
flashing. The horn will turn Off at the preset delay time you set above (0 -60 seconds). The red light will continue to
flash until the TEST button is released.
Setting the Overfill Alarm Horn’s Volume Level
1. Locate the adjustment set screw (1/16” Hex wrench) on the exterior of the Overfill Alarm’s horn cover (see
Figure 1 on page 4).
2. Turn the adjustment screw counterclockwise to increase the dB level of the horn or clockwise to decrease its
dB level.
Testing the Overfill Alarm with the Console
With the Overfill Alarm and Acknowledgment Switch (if installed) connected to the console, consult the setup
instructions for your console and perform the Output Relay setup procedure to recognize the Overfill Alarm.
1. Turn power Off to the console and the Overfill Alarm. Put a jumper between the two Overfill Alarm relay
connections in the console (see Figure 6).

Testing Overfill Alarm W/o Acknowledgment Switch
1. Reapply power. If the Overfill Alarm was wired properly, the alarm horn will sound immediately followed by the
red alarm light flashing.
2. Turn Off power to the console and to the Overfill Alarm. Remove the test jumper between the Output Relay
connections.
Testing Overfill Alarm With Acknowledgment Switch
1. Turn power Off to the console and the Overfill Alarm. Put a jumper between the two Overfill Alarm relay
connections in the console (see Figure 6).
2. Stand by the Acknowledgment Switch and have someone reapply power to the console and Overfill Alarm. If
the Overfill Alarm was wired properly, the alarm horn will sound immediately followed by the red alarm light
flashing.
3. Press the RESET button on the front of the Acknowledgment Switch. The alarm horn and red flashing light
should shut off. The ACKNOWLEDGED light on the front of the switch should be On. (Pressing the RESET
button shuts Off the alarms but does not clear the alarm. The cause of the alarm must be removed before the
ACKNOWLEDGED light will turn Off.)
4. Turn Off power to the console and to the Overfill Alarm. Remove the test jumper between the console’s
Output Relay connections.
5. Reapply power to the console and to the Overfill Alarm. The ACKNOWLEDGED light should now be Off
because the cause of the alarm (in this case, the test jumper) has been removed.
