FAQs
How do smoke detectors in an early fire-detection system work?
Petros supplies smoke detectors that continuously sample the air for by-products of combustion. Most units are photo-electric: a light beam inside the sensing chamber is scattered by microscopic smoke particles, triggering the alarm long before flames appear. Some models combine photo-electric and heat sensing to reduce false alarms and provide faster response to a wider range of fires.
What types of smoke detectors does Petros offer and when should each be used?
We carry three main categories: • Photo-electric: Best for smouldering or slow-burn fires common with upholstery, wiring and overheated appliances—ideal for living areas, offices and hotel rooms. • Ionization: Quicker at detecting fast-flame fires involving paper or flammable liquids—often placed near kitchens or boiler rooms (though not directly above cooking equipment). • Multi-sensor (photo-electric + thermal ± CO): Provide the earliest warning and the lowest false-alarm rate in mixed-risk environments such as warehouses, data centres and industrial plants.
Where should smoke detectors be installed for maximum effectiveness?
For residential properties, national codes require at least one detector on every level, inside each sleeping room and outside each bedroom cluster. Mount the unit on the ceiling or high on a wall 10–30 cm (4–12 in.) below the ceiling apex, away from HVAC vents or ceiling fans. In commercial premises, detectors are spaced according to the area’s airflow, ceiling height and fire load; Petros engineers perform a site survey to create a compliant layout under NFPA 72 and local regulations.
How often do smoke detectors need to be tested, cleaned and serviced?
Press the built-in test button every month to verify power and sounder operation. Detectors should be gently vacuum-cleaned twice a year to remove dust that can impede the sensing chamber. Petros offers annual professional servicing that includes functional testing with calibrated aerosol smoke, battery health checks, firmware updates and documentation for regulatory audits.
Can the detectors be connected to other safety or building-management systems?
Yes. All Petros detectors are available in 24 V addressable models that tie into fire-alarm control panels (FACPs). The FACP can then trigger visual/audible notification devices, elevator recall, HVAC shutdown, sprinkler pre-action valves or remote monitoring via BACnet, Modbus or cloud APIs. For homes, we supply wireless models that integrate with smart-home hubs and send instant alerts to mobile devices.
What is the expected lifespan of a smoke detector and when should it be replaced?
The sensing elements gradually lose sensitivity as they age. Most manufacturers recommend full replacement after 10 years for photo-electric and 8–10 years for ionization models, even if the test button still works. Petros labels each detector with its manufacture date and offers a replacement reminder service so your system never operates beyond its certified life.
