The ACI 104105 is a 24-volt amber indicating light designed for use in HVAC, electrical, and building automation control panels. The round amber lens provides a clear visual status signal, making it straightforward for technicians to confirm circuit or equipment states at a glance. The unit ships with a leads connector for direct wiring into low-voltage control circuits. At 0.2 pounds, it is a compact, lightweight component suited for panel mounting in commercial and residential applications. Licensed electricians and HVAC controls technicians are the primary installers of this type of pilot light.
This indicating light is used in control panel assemblies where a 24-volt status indicator is required. Typical applications include HVAC unit enable circuits, fan or pump status indicators, and building automation field panels. The amber lens color is commonly used to signal a caution, standby, or intermediate status state in panel wiring conventions. It is well-suited for both new panel builds and retrofit installations where a low-voltage pilot light needs to be replaced or added.
Designed as an OEM-style replacement or addition for 24-volt control panels requiring a round amber pilot indicating light with a leads connector.
Installation is typically performed by a licensed electrician or HVAC controls technician. De-energize the control panel and verify zero voltage before making any wiring connections. Secure the leads connector per the panel wiring diagram and confirm polarity where required by the circuit design. Follow applicable NEC guidelines for low-voltage control wiring in panel enclosures.
