1. What is the Fire Lite Battery Life Calculation?

The Fire Lite battery life calculation estimates how long a battery will last based on its capacity (Ah), voltage (V), and the load (W) being powered. This is crucial for designing and maintaining reliable fire alarm systems.

2. How Does the Calculator Work?

The calculator uses the battery life equation:

\[ \text{Life (hours)} = \frac{\text{Fire Lite Battery Ah} \times V}{\text{Load W}} \]

Where:

\( Ah \) — Battery capacity in amp-hours
\( V \) — Battery voltage in volts
\( W \) — Load power in watts

Explanation: The equation calculates how many hours the battery can supply the given load before being fully discharged.

3. Importance of Battery Life Calculation

Details: Accurate battery life estimation is crucial for ensuring fire alarm systems remain operational during power outages and meet code requirements for backup duration.

4. Using the Calculator

Tips: Enter the battery capacity in Ah, voltage in V, and load in W. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical Fire Lite battery capacity?
A: Common capacities range from 4Ah to 100Ah depending on the system size and backup requirements.

Q2: What voltage do Fire Lite batteries typically use?
A: Most Fire Lite systems use 12V or 24V batteries.

Q3: How do I determine the load in watts?
A: The load is the sum of all powered devices in the system. Check device specifications or consult system documentation.

Q4: Are there factors that affect actual battery life?
A: Yes, temperature, battery age, and discharge rate can all affect actual performance.

Q5: What's the minimum required backup time for fire alarm systems?
A: NFPA 72 typically requires 24 hours of standby plus 5 minutes of alarm, but local codes may vary.
