Explain how the system works?
The Linear Heat Detection (LHD) detects heat on fire along the engine bay. When the temperature exceeds a ser threshold the cable sends a signal is the control panel triggering the fire detection system
The control panel displays a fire indicator for the battery compartment, and the buzzer alarm sounds to alert the operator
The suppression system is activated automatically when the LHS detect the temperature rise triggering the discharge of foam based suppressant to supparss the fire
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.
The alarm will continue to sound until the operator presses the “accept” button on the control panel to silence it.
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.

03
Alarm Acknowledgment
The suppression system automatically activates when the LHD cable detects a temperature rise releasing SNF LITH+ a lithium-ion battery fire suppressant
04
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.
05
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.
06
Automatic Suppression Activation
The The alarm will continue to sound until the operator presses the”accept” button on the control panel to silence it.

Frequently asked Questions
What is FDAS and FDSS?
FDAS (Fire Detection and Alarm System) and FDSS (Fire Detection and Suppression System) are advanced fire safety systems designed for high-risk zones like engine bays in Internal Combustion Engine (I.C.E.) buses. They provide rapid fire detection, swift suppression, and comply with AIS-135 standards.
How does the system detect a fire?
A Linear Heat Detection (LHD) cable senses abnormal temperature rise in the engine bay. When it crosses the threshold, it signals the control panel, triggering the alarm and suppression system.
What happens when a fire is detected?
The control panel shows a fire alert and activates an audible buzzer. Simultaneously, the suppression system discharges foam to contain the fire automatically.
Can the system be manually activated?
Yes. If automatic suppression fails, the operator can press the manual activation button on the control panel or pull the pin on the suppressant cylinder to release the agent
How is a false alarm or error handled?
The alarm continues until the operator acknowledges it by pressing “accept” and then “reset” after resolving the issue to restore normal function.
What type of suppressant is used in FDSS?
A foam-based agent is used, which:
- Forms a thick barrier to cut off oxygen
- Rapidly cools the fire and components
- Prevents re-ignition
- Discharges at 18–20 bar within 5 10 seconds
- Leaves minimal residue
- Is safe around electronics
Is the system durable for transport use?
Absolutely. It’s built for rugged performance in harsh environments, offering:
- Protection to vehicle components
- during fires
- Reduced downtime
- Low maintenance
- Long service life
What components are included in the system?
Control Panel (supports up to 3 zones, EMI/EMC certified)
- Fire Strobe and Siren (90dB alert, visible in smoke)
