Overview
ISO 15763:2002 specifies requirements, definitions and test procedures for vehicle alarm systems (VAS) intended for installation in buses and commercial vehicles with a maximum authorized total mass greater than 3.5 t. The standard covers both original equipment and aftermarket alarm systems designed to detect and indicate unauthorized opening of doors, luggage compartments, bonnet/hood, emergency exits, tilting of the driver’s cabin, trailer disconnection and power-supply interruption. Volumetric protection systems are optional and tested against their own specifications.
Key topics and technical requirements
- Scope and terminology: Defines VAS components such as detector/sensor, control equipment, setting–unsetting devices, warning devices, immobilizers and scanners.
- Perimeter protection: VAS shall detect unauthorized opening of doors, hatches, emergency exits, bonnet/hood and related events.
- Performance and timing:
- Alarm outputs must be provided within 1 s of an alarm condition.
- Unsetting/cancelling alarms must act within 1 s.
- Perimeter protection must be active within 10 s after setting; optional sensors within 60 s.
- Optical status-change signals limited to ≤ 3 s duration.
- Setting/unsetting mechanisms: Acceptable methods include mechanical or coded key switches with tamper resistance (key profile with ≥ 1 000 permutations; cylinder tensile and torque requirements such as 600 N tensile, 25 N·m torque). Keys must not expose codes on components.
- Alarm outputs: At least one acoustic warning device is required; optical or remote signaling (radio) are optional. Panic alarms (deliberately operated) must operate acoustic alarm at minimum and be cancelable by the user without affecting engine start.
- Design considerations: Components must minimize false alarms, resist tampering and not change system state due to power interruptions.
- Testing and durability: Comprehensive test suite including functional tests, electrical and EMC tests (ISO 7637, ISO 10605, ISO 11451/11452), temperature/humidity accelerated ageing, corrosion (salt mist), vibration, bump, drop, acoustic durability and volumetric protection functionality. Marking and documentation requirements are also specified.
Applications and users
- Vehicle manufacturers (OEMs) specifying integrated security for buses and heavy commercial vehicles.
- Alarm system designers and electronics suppliers developing VAS compliant with ISO 15763.
- Aftermarket installers and fleet operators specifying theft/entry protection for vehicles >3.5 t.
- Test laboratories and certification bodies performing functional, environmental and EMC testing.
- Regulators and procurement teams referencing standard requirements for vehicle security systems.
