Explain how the system works?
The Linear Heat Detection (LHD) cable senses abnormal heat in the battery pack and triggers the fire detection system when temperatures exceed a set threshold.
The control panel displays a fire indicator for the battery compartment, and the buzzer alarm sounds to alert the operator
The alarm will continue to sound until the operator presses the “accept” button on control pannel to silence it
The suppression system automatically activates when the LHD cable detects a temperature rise, releasing SNF LITH+, a lithium-ion battery fire suppressant
If the system fails to activate automatically, the operator can manually release SNF LITH+ by pressing the control panel button or pulling the pin on the cylinder to open the solenoid valve.
In case of a false alarm or error, the operator can silence the alarm by pressing the "accept" button, correct the issue, and press the "reset" button to restore system functionality.
Explain how the system works?
01
Fire Detection
The Linear Heat Detection (LHD) cable senses abnormal heat in the battery pack and triggers the fire detection system when temperatures exceed a set threshold.
02
Fire Alarm Activation
The control panel displays a fire indicator for the battery compartment, and the buzzer alarm sounds to alert the operator
03
Alarm Acknowledgment
The alarm will continue to sound until the operator presses the “accept” button on control pannel to silence it
04
Automatic Suppression Activation
The suppression system automatically activates when the LHD cable detects a temperature rise, releasing SNF LITH+, a lithium-ion battery fire suppressant
05
Manual Activation (If Automatic Fails)
If the system fails to activate automatically, the operator can manually release SNF LITH+ by pressing the control panel button or pulling the pin on the cylinder to open the solenoid valve.
06
Error or False Alarm Handling
In case of a false alarm or error, the operator can silence the alarm by pressing the “accept” button, correct the issue, and press the “reset” button to restore system functionality.
