The RLE Power Fail Monitor (PFM) is a convenient power failure sensor that detects the loss of utility power.
The PFM provides early warning that power has been lost and that reserve power needs to be activated. On loss of power, the unit sends a signal via its Form C output relay.
The PFM plugs directly into a standard (USA) 120V power outlet and screws securely into the outlet to ensure that it is not accidentally disconnected. The PFM integrates easily with existing alarm monitoring systems, including RLE’s Falcon monitoring products.
