The Simplex 478-332 transformer provides 120VAC, 60Hz input power for the Simplex 4010 fire alarm control panel. It is the original-equipment replacement transformer for that platform.
Specifically, this transformer mounts inside the 4010 FACP enclosure and steps line voltage down for the panel’s DC supply. As a result, replacing a failed unit restores normal panel operation. Also, the 478-332 is a direct OEM Simplex part — no field calibration is required.

Panel Cross-Reference — Don’t Order the Wrong Transformer
Simplex 478-series transformers are panel-specific. For example, the 478-352 is the 120VAC transformer for 4100U/ES and 4010ES — not the same part as 478-332. Therefore, confirm the panel model number before ordering. However, if you are unsure, our team can match the right transformer against your panel’s parts list.
