What is an important factor when considering the secondary power supply for alarm systems?

When evaluating the secondary power supply for alarm systems, the length of battery life is a crucial consideration. A reliable and extended battery life ensures that the alarm system remains operational during power outages or when the primary power source fails. This is particularly important for maintaining security and safety, as any interruptions in power can compromise the system’s effectiveness in detecting threats.

By providing a dependable power source for an extended duration, the system can continue to function seamlessly, allowing for uninterrupted monitoring and alerting. The risk of false alarms or system failures due to short battery life can lead to significant consequences, so prioritizing longevity in the battery supply is essential for the overall reliability of alarm systems.

Other factors, such as the type of sensor used, noise level, and frequency of maintenance, may influence the performance and operation of the alarm system but do not directly affect the capacity of the secondary power supply in terms of its ability to sustain the system during outages.
