Smoke Detectors — Fire Alarm Sensors in Tbilisi
Smoke Detectors (Smoke Alarms) are most important components of fire alarm systems that detect at early stage of fire smoke particles in air and instantly send signal to fire panel in Tbilisi and throughout Georgia. These devices provide early warning at fire start (often several minutes before flame appears), giving critical time for safe evacuation of people and fire extinguishing, which is necessary for all residential houses, apartments, offices, hotels, hospitals, and public buildings. LAGI offers full range of smoke detectors: optical (photoelectric) detectors (most common, ideal for slow fires), ionization detectors (fast flame detection), dual sensor detectors (optical + ionization, maximum accuracy), addressable detectors (unique ID, precise location), conventional detectors (zone system), standalone detectors (built-in siren, battery powered), interconnectable detectors (wireless interconnect, all detectors sound simultaneously), 10-year battery models. All detectors comply with European standard EN 54-7.
Main Types of Smoke Detectors
- Optical (photoelectric) detectors — LED + photodiode, detect smoke particles by light scattering, ideal for slow smoldering fires, fewer false alarms, most common.
- Ionization detectors — radioactive source (Americium-241), detect invisible smoke particles, ideal for fast flaming fires, faster response.
- Dual sensor detectors — optical + ionization combination, detect both fire types, maximum accuracy, false alarm minimization, recommended.
- Addressable detectors — unique ID, fire panel knows exactly which detector triggered, 2-wire connection, ideal for large buildings, hotels.
- Conventional detectors — zone system, 4-wire connection, cheap, ideal for small buildings, offices, residential houses.
- Standalone detectors — built-in 85dB siren, 9V battery powered, no panel needed, ideal for apartments, small houses, cheap solution.
FAQ — Frequently Asked Questions
Optical (photoelectric) detectors — use LED light and photodiode, detect smoke particles by light scattering, ideal for slow smoldering fires (furniture, fabric), fewer false alarms, safe (no radioactive material), recommended for residential homes. Ionization detectors — use radioactive source (Americium-241), detect invisible smoke particles, ideal for fast flaming fires (paper, gasoline), faster response, but more false alarms. Recommendation: optical — residential homes, offices. Ionization — kitchens, warehouses. Dual sensor — best option (both fire types).
Correct smoke detector placement is critical for effective protection. Recommendations: 1) in all bedrooms — detector must be in all bedrooms and in corridor near bedrooms. 2) on all floors — minimum one detector per floor including basement and attic. 3) on ceiling — detector must be installed on ceiling or on wall 10-30cm from ceiling (smoke rises up). 4) avoid — kitchen (false alarms when cooking), bathroom (steam), windows/doors (air flow). 5) distance — maximum 10-15m distance between detectors. 6) testing — monthly press test button and ensure siren works.
Smoke detector battery life depends on type. Standard 9V battery — 6-12 months, detector beeps when battery weakens (one beep every 30-60 seconds), replace immediately. 10-year lithium battery — 10 years, built into detector, no replacement needed, after 10 years replace entire detector. AC power (220V) + backup battery — backup battery 1-2 years. Recommendation: replace battery twice per year (when changing clocks), replace entire detector after 10 years (sensor ages and loses accuracy).
