Questions about this item

How often should the sensor be tested or replaced to ensure it still detects power loss reliably?

The sensor has no user-serviceable parts or published replacement interval; treat it as a fit-and-forget device and verify operation during routine UPS or PDU maintenance.

What is the maximum number of monitored circuits or devices the sensor can report on before it saturates?

The sensor provides a single dry-contact output that changes state on power failure, so it monitors one supply path per unit.

How much heat does the sensor add to a rack when it is powered continuously?

Power draw is minimal and the unit generates negligible heat; it does not require additional cooling beyond normal rack airflow.
