Installation guide for the X10 PRO PSC01 PowerFlash Security Interface, which converts security panel, driveway sensor, or doorbell contacts into X10 wireless commands.
The X10 PRO PowerFlash Security Interface (PSC01) converts a "make or break" contact signal from a security panel, driveway sensor, doorbell, or magnetic door/window switch into an X10 wireless command — triggering lights, chimes, or sirens automatically.
The PowerFlash module sends an X10 signal in response to activation from an equipment output — security panels, driveway sensors, doorbells, and similar devices. It can be triggered by a low-voltage output or by a dry contact switch closure. On activation, it sends an X10 ON-type signal; when the trigger clears, it sends an X10 OFF-type signal.
House Code Dial: Letters A–P. Unit Number Dial: Numbers 1–16. Each receiver module is set to a unique (or shared) unit number; the controller must be set to the same house code as the receivers it controls.
Residential wiring is typically split-phase — if a receiver doesn't respond, check that its breaker shares the same phase as the controller (swap breakers if needed), or install a Phase Coupler for more reliable whole-home communication. See x10pro.com > Technical Support > PLC Troubleshooting.
| Mode | Engaged (triggered) | Disengaged (cleared) |
|---|---|---|
| 1 | Sends ALL LIGHTS ON (wall switches/lamp modules) + ON at Set Address (appliance/fixture modules) | Sends OFF at Set Address; other switches/modules remain ON |
| 2 | Continuous ALL LIGHTS ON / ALL UNITS OFF flashing (sets off X10 siren after a few cycles) | Flashing stops; switches/modules remain ON (siren stops after a few seconds) |
| 3 | Sends ON at Set Address | Sends OFF at Set Address |
Use with no wires attached (Output Mode set to 3): pressing TEST sends an X10 ON command at the Set Address; releasing sends an X10 OFF command.
