Frequently Asked Questions

Fire Alarm System FAQ

A fire alarm system is an integrated life-safety system designed to detect fire-related conditions, process alarm signals and notify occupants or responsible personnel through appropriate alarm and notification devices.

Conventional systems generally identify an alarm by zone, while addressable systems can identify individual field devices or addresses. The appropriate architecture depends on building size, system requirements, design objectives and project conditions.

Yes. AJ FSES can provide fire alarm layout drawings, device placement, zoning or loop architecture, riser diagrams, circuit information, interface documentation and other project-specific engineering drawings.

Yes. Where required by the system design, we prepare battery sizing and voltage-drop calculations to support proper power and circuit design.

Yes. Our services can include supply, installation, programming, testing, commissioning and handover, depending on the project scope.

Yes. We provide inspection, preventive maintenance, troubleshooting, repair, testing and annual maintenance support for fire alarm systems.

Depending on project scope and applicable requirements, fire alarm engineering may reference NFPA 72, Bangladesh National Building Code (BNBC), RSC requirements, FSCD requirements and other applicable authority or project criteria.
