The MECOAlarm™ Stainless Steel AST Overfill Alarm is an inexpensive battery operated, intrinsically safe overfill alarm. Assists in overfill prevention. The Meco Alarm can be used as an overfill alarm or be configured to be used as an interstitial leak detector. When used as an interstitial monitor, Meco can custom build the probe length to meet any tank manufacturer's specifications. Where local regulations require, Meco offers a lighted version of this product.
The MECOAlarm™ runs on a 9V dc battery (Battery not included. Lithium battery is recommended in all installations for extended life). No power consumption in the "Non-alarm" condition provides years of life from a Lithium battery. Ultra low power consumption after Alarm reset.

Typical Tall Tank Installation
The MECOAlarm™ case has provisions inside the cover for wall mounting. Separate the case from the float switch assembly at the bushing and place the case at a convenient location for the operator. The maximum separation between the case and the float switch assembly is 500 feet.The case may be mounted to any surface using the two mounting holes provided under the cover. Use conduit as required by local codes from the float switch assembly to the case and extend the wire to the case using two conductors.
For all tank installations, the installer must adjust the bottom of the float switch to establish the alarm point in accordance with Local Code, NFPA 30A or UFC requirements as applicable for the particular installation. The alarm point may be determined from the tank capacity chart.
