A Vehicle Fire Alarm System (VFAS) is a safety solution designed to detect fire inside engine compartment of a vehicles—commonly used in school buses, trucks, fuel tankers, heavy machinery, and passenger transport vehicles.
Purpose
Early detection of fire in the engine, battery compartment, or passenger cabin.
Quick activation of alarms (visual & audio) to warn driver and passengers.
Compliance with AIS 135 (MoRTH India) and international safety standards.
Main Components
Fire Detection
LHS (Linear Heat Sensor) Cable – detects rise in temperature.
Smoke or flame detectors (optional for passenger cabin).
Control Panel / ECU – receives fire signal, processes it, and triggers actions.
Alarm System
Hooter/Buzzer – audible warning for driver and passengers.
Dashboard Indicator / Flashing Lights – visual alert.
Working Process
Fire starts → heat reaches detection threshold.
LHS cable senses short-circuit → sends signal to Control Panel.
Control Panel activates
Alarm (hooter + light indicator).
Applications
School Buses & Staff Buses – mandated by transport safety norms.
Fuel Tankers & Hazardous Goods Carriers.
Mining & Construction Equipment (excavators, dumpers, loaders).
City Transport Vehicles (metro feeder buses, long-distance coaches).
Standards & Compliance
AIS 135: Automotive Industry Standard (India) for fire detection & suppression in buses.
MoRTH: Ministry of Road Transport & Highways mandates it for certain vehicle categories.
International Standards: NFPA 17/2001, ECE R107.
