1. What is the Fire Lite ES200X Battery Calculator?

The Fire Lite ES200X Battery Calculator helps determine the required battery capacity for Fire Lite ES200X fire alarm control panels based on standby current and alarm current draw.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• ES200X Standby A — Standby current in amps
• Alarm A — Alarm current in amps
• 24 — Hours of standby operation
• 0.083 — 5 minutes of alarm operation (in hours)
• 1.25 — Safety factor (125% of calculated capacity)

Explanation: The equation calculates the total amp-hours needed for 24 hours of standby plus 5 minutes of alarm, with a 25% safety margin.

3. Importance of Proper Battery Sizing

Details: Correct battery sizing ensures the fire alarm system will operate during power outages for the required duration per NFPA standards.

4. Using the Calculator

Tips: Enter the measured standby current and alarm current in amps. Values must be non-negative. Use manufacturer specifications or actual measured values.

5. Frequently Asked Questions (FAQ)

Q1: Why is there a 1.25 multiplier?
A: The 25% safety factor accounts for battery aging, temperature effects, and ensures reliable operation over the battery's lifespan.

Q2: What battery types are suitable?
A: Sealed lead-acid (SLA) batteries are typically used. Consult Fire Lite documentation for approved battery models.

Q3: How often should batteries be replaced?
A: NFPA recommends replacement every 3-5 years or when capacity drops below 80% of rated capacity.

Q4: What if my system has multiple devices?
A: Include the total standby and alarm current for all connected devices when calculating battery requirements.

Q5: Does this calculator account for temperature?
A: No, for extreme temperatures (below 20°C/68°F), additional capacity may be needed.
