An inexpensive monitor is the clock on a microwave or the timer on a VCR. Meanwhile, smoke detectors also contain a UPS - that 9 volt battery. If power should be interrupted, then the battery simply takes over.
However, what is the detector supposed to do when power is lost? Flick off its circuit breaker to confirm.
