Fire Lite PSM 104 Power Supply Module Repair Service

Professional diagnostic and board-level repair service for this Fire Lite PSM 104 Power Supply Module.

Fire‑Lite PSM‑104 is an auxiliary power supply module designed for the Sensiscan 1000 fire alarm control panel, providing 120 VAC input and regulated output to the panel’s internal circuitry. Common failures on this model include burnt or tripped fuses, degraded capacitors on the rectifier/filter stage, and transformer winding insulation breakdown that causes voltage drops or shorted secondary windings. First‑check diagnostics: verify incoming AC voltage and continuity of the primary winding; inspect the output rail for correct DC voltage and ripple using a multimeter; visually examine the PCB for burned components, cracked solder joints, or signs of moisture ingress before proceeding to component replacement.
