The residential alarm's power supplies are described as primary and secondary. How many power supplies does it have?

Explanation:
The key idea is that “primary” and “secondary” describe two separate power sources. The primary power supply is the normal source from the building’s electrical system, powering the alarm when power is available. The secondary power supply is a backup, typically a rechargeable battery, that keeps the system running if the main power is lost. Because there are two distinct sources, the residential alarm has two power supplies.
