Backup power in the form of emergency power supply or batter backup is needed for a fire alarm system
True or false
Homework Answers
A basic fire alarm system uses only batteries as their primary power source and battery must be sufficient to operate under quiescent load.
So, backup power in form of emergency power supply and battery power is needed for fire alarm system.
So, it is true.

Hospitals typically require backup generators to provide electricity in the event of a power outage. A certain hospital has two backup generators, so that power is still available if one of them fails during a power outage. These generators operate independently, so that if one backup fails, the failure will not affect the operation of the other generator. Assume that both emergency backup generators are the same make and model, which is known to fail 21% of the times when...

(UPS Battery) On January 1, 2015, you bought a backup battery for your office uninterruptible power supply (UPS) system. In each of the next three years, the battery can fail and a new battery needs to be bought (if you want to keep using the UPS system). The maximum lifespan of the battery is four years; i.e., the battery must be replaced after four years. Due to chemical properties, the probability of the battery failure is fixed at 20% in...
