The MAO installs between a controller and an actuator to provide adjustable analog manual override when needed. In normal operation two (2) analog signals route from the controller through the MAO to each actuator. Flip the override switch from automatic to manual on either MAO output and vary the analog signal independently. Each output can have a different span and be analog current or voltage. When a switch is in manual position, an alarm output contact is made or broken (optional) to indicate override is in effect.  The MAO is covered by ACI's Two (2) Year Limited Warranty.
