Overfill Alarm & Acknowledgement Switch

Veeder-Root's TLS Overfill Alarm provides an early warning of potential tank bulk delivery overfills as required by the Federal regulations governing underground storage tanks. Wired to an alarm relay in a TLS-450TLS-350R, TLS-350, TLS-350J, TLS-300, TLS-300C, TLS-300i, TLS-300, ILS-350, and TLS-250 or TLS-250i System, the alarm relay activates the TLS overfill alarm horn and light when a potential overfill is detected. All TLS systems have programmable overfill alarm limits that can be set for each tank at a location.

An optional Alarm Acknowledgement Switch is also available for locations where driver intervention is required by local codes. When the driver presses the acknowledgement button, the overfill alarm shuts off and the alarm acknowledgement light illuminates. This light will stay on until the TLS prints an inventory increase report.

A built-in timer lets you adjust length of time that the audible alarm will stay on from 0 to 60 seconds. You can also adjust noise level from 78 to 103dB (at 10 feet).
