The Edwards 2490027 is a 120 VAC primary to 26.4 VAC secondary power transformer used as a service / replacement part in Edwards fire alarm panels. First, note: this is a transformer — not a pull station, not a notification appliance, and not a stand-alone listed device. Specifically, it is designed as a component for the E-FSC502 conventional fire alarm panel (the FireShield Conventional 5-zone family). Therefore, it should be specified only as a like-for-like replacement when the original panel transformer fails.
What the Edwards 2490027 transformer does
This transformer steps standard 120 VAC building power down to the lower secondary voltage required by the panel’s internal power supply. As a result, the panel can drive its CPU, NAC outputs, and IDC supervision circuits from a regulated low-voltage rail. In addition, the design includes a thermal class rating suitable for continuous panel operation.

What this part is NOT
However, the 2490027 is not a complete fire alarm panel, an end-use signaling appliance, or a stand-alone UL-listed device. Therefore, agency listings (UL 864 etc.) live at the host panel level, not at the transformer part level. Furthermore, this is not a pull station — despite some catalog mis-tagging that lists it under pull-station search terms.
Installation notes
As a result, the 2490027 should only be replaced by a qualified fire alarm technician with the host panel powered down and locked out. Specifically, verify the host panel’s wiring diagram before swap-out. In addition, retain the original transformer for warranty or RMA purposes if applicable.
