COMPARISON POINT
Building and retrofit constraints
Document cable routes, protected finishes, occupied areas, drilling limits, floor transitions and project downtime before comparing architectures.
SYSTEM SELECTION GUIDE
Wireless vs Wired Fire Alarm Systems: Buyer Checklist
The right architecture depends on the building, project stage, evacuation strategy and maintenance capability—not on a universal claim that one technology is always better.
COMPARISON POINT
Communication supervision
Ask how device loss, low battery, wiring faults, interference and panel communication failures are detected, displayed and escalated.
COMPARISON POINT
Power and backup planning
Compare mains, loop, battery and backup requirements at panels, field devices, repeaters, gateways and notification appliances.
COMPARISON POINT
Coverage and capacity evidence
For wireless systems, open-area distance is not a building guarantee. Use drawings, site surveys and staged tests. For wired systems, confirm loop or zone capacity and cable constraints.
COMPARISON POINT
Maintenance and change control
Record battery replacement, fault investigation, spare-device pairing, firmware control, cable inspection and responsibility for future extensions.
COMPARISON POINT
Tender questions
Require a system diagram, device schedule, compatible-device list, failure-behaviour matrix, backup calculations and exact model documentation.
BUYER FAQ
Questions buyers should confirm
Are wireless fire alarm systems easier to install?
They may reduce new cabling in some retrofits, but survey, repeater, power, supervision and maintenance work still require project planning.
Can wired and wireless devices be combined?
Selected hybrid platforms may support both, but compatibility, capacity and failure behaviour must be confirmed for the exact panel and firmware.
How should a buyer compare quotations?
Compare the complete architecture, device count, power and backup, testing, commissioning, documentation, maintenance and lifecycle cost—not only unit prices.
