FK915

This alarm unit only has to work, once, to pay for itself. Over-draining of SLA batteries will inevitably cause their failure. This electronic circuit continually monitors the battery voltage and, if it should fall below the minimum set point, the FK915 will sound an audible alarm. Further battery protection may be achieved by adding a disconnect circuit to ensure no further drain.
