How to work with Battery calculator for IRIS Fire Alarm Control Panel

1. Press the “Start” button – in the input data fields are set automatically with values by default.

2. Enter the number of the used loops – 1 - 4.

3. Enter the number of the used devices:
- Enter in the “Standby mode” columns the number all devices connected to Loop 1 - Loop 4.
- Enter in the “FIRE mode” columns the number of activated devices in case of fire alarm mode.

4. Enter the number of the sounders sorted according the set sound level in the panel menus:     
- In the column “HIGH” enter the number of the sounders with set HIGH sound level in the panel*.    
- In the column “LOW” enter the number of the sounders with set LOW sound level in the panel*.      
- Tone type is set automatically to 27 - this is the main tone type for the system. You can change it with other tone type from 1 to 32. (Note: The tone types are described in details in the installation manuals of the sounders SensoIRIS series.)

* Note: The sound level is set individually for every sounder in the panel menus. 

5. Enter the number of activated zones in fire alarm mode.

6. Enter if necessary the values for activated inputs and outputs, as refer to the noted limits.

7. If necessary change the set by default hours for operation of the panel in standby mode (according EN54-14:2006 for a min. time from 30 to 72 hours) and fire alarm mode (according EN54-14:2006 - min. a half an hour).

8. Press the “Calculate” button.

9. Use the "Print" button (in the upper right corner) for printing the final calculations on the screen.

ATTENTION:
The calculator is designed for calculating the battery capacity for fire alarm panel IRIS equipped with TTE loop expanders! 

IMPORTANT NOTE!
The calculated value for the battery capacity is a minimum. This means, that for the current fire installation the constructor must use a battery with close in value but higher capacity – it is strongly recommended the calculated battery capacity to be increased with 25%, so to guarantee a reserve charge with reducing the battery capacity as a result of aging. For example, if the calculated battery capacity is 30.3Ah, then it is recommended to use a battery with capacity of 38Ah.
