*** The PFM has been redesigned! ***
The new version of the PFM features a smaller form factor, can be used in both domestic and international applications, and is ready to ship now.
The Power Fail Monitor (PFM) is a power failure sensor that detects the loss of utility power. It provides early warning that power has been lost and that reserve power needs to be activated, and sends an alarm signal to a facility monitoring device via its Form C output relay.
The unit plugs directly into a standard outlet and includes type A, C, G, and I blades for domestic US and international installations.
