Combination Smoke & Carbon Monoxide Detectors — In Tbilisi
Combination Smoke and Carbon Monoxide Detectors (Smoke and CO Alarm) are 2-in-1 safety devices that combine a photoelectric smoke detector and an electrochemical carbon monoxide (CO) sensor in one compact housing and provide dual protection from fire (smoke) and invisible killer gas (CO) in apartments, houses, offices, hotels, hospitals in Tbilisi and throughout Georgia. These detectors detect smoke at 0.1-0.2 dB/m concentration and CO in the 30-999ppm range, emit an 85dB siren, provide economy (one device = 2 detectors), simple installation (mounting one device instead of two), aesthetics (one compact device on the ceiling) and complete protection (smoke + CO). LAGI offers combination smoke and CO detectors with full functionality: photoelectric smoke sensor (0.1-0.2 dB/m, detects slow-burning smoke), electrochemical CO sensor (30-999ppm, 10-year lifespan), 85dB siren (powerful audible alarm), LED indicators (green = normal, red = alarm), test button (monthly testing), battery power (9V or AA, 1-2 year lifespan) or 220V AC power (backup battery), ceiling mount (optimal detection), interconnect (radio or wire, all detectors simultaneously), smart models (Wi-Fi/Zigbee, smartphone notification). All detectors comply with EN 14604 (smoke) and EN 50291 (CO) standards.
Key Advantages of Combination Detectors
- Dual protection — one device protects from both fire (smoke) and CO poisoning (invisible killer gas).
- Economy — one combination detector (50-80 GEL) is cheaper than 2 separate detectors (smoke 30-50 GEL + CO 40-60 GEL = 70-110 GEL), savings 20-30 GEL.
- Simple installation — install one device instead of two, save time and effort, one hole in ceiling instead of two.
- Aesthetics — one compact device on ceiling instead of 2 detectors, neater appearance, less visual clutter.
- One battery — one battery for both sensors, no need to replace 2 batteries, less maintenance.
- Complete protection — smoke sensor (detects fire) + CO sensor (detects CO poisoning) = complete protection for your family.
Frequently Asked Questions
A combination smoke and CO detector is needed because it protects from two different threats: 1) smoke (fire) — fire produces smoke, smoke inhalation is the main cause of death in fires (80% of fire victims die from smoke inhalation, not from flames), smoke detector detects smoke → siren → people evacuate → life protection. 2) carbon monoxide (CO) — CO is an invisible, odorless, tasteless gas (invisible killer), CO is produced during incomplete combustion (gas heater, stove, generator, car), CO inhalation causes headache, nausea, confusion, heart attack, death (30-60 minutes at 400ppm CO), CO detector detects CO → siren → people evacuate → life protection. Why combination — fire and CO often occur simultaneously (fire produces CO), separate detectors: smoke detector (detects smoke, but not CO) + CO detector (detects CO, but not smoke) = 2 devices, 2 batteries, 2 installations, 70-110 GEL. Combination detector: detects smoke and CO = 1 device, 1 battery, 1 installation, 50-80 GEL → savings 20-30 GEL + simpler + more aesthetic. Recommendation: if you have gas heating, stove, generator → combination detector mandatory (smoke + CO), if no gas → smoke detector sufficient.
Proper installation of a combination smoke and CO detector is critical for effective detection: where to install — bedroom: install 1 detector in each bedroom (on ceiling, center), people sleep → don't sense smoke/CO → detector will wake them. Hallway: install 1 detector in hallway (on ceiling, center), hallway connects all rooms → smoke/CO will spread to hallway. Living room: install 1 detector in living room (on ceiling, center), people often in living room → detector will warn them. Kitchen: don't install detector in kitchen (false alarms during cooking), install detector 3-5m away from kitchen. Bathroom: don't install detector in bathroom (false alarms from steam). Gas heater/stove: install detector in same room as gas heater/stove (CO risk), 1-3m distance from heater. Basement/garage: install detector in basement/garage (CO risk from car, generator). How to install — on ceiling: install on ceiling (center), smoke and CO rise up → detector on ceiling detects first. On wall: if ceiling installation impossible → install on wall (15-30cm from ceiling). Recommendation: minimum 1 detector per floor, 1 detector in each bedroom, 1 detector in hallway, 1 detector in living room → complete coverage.
Regular testing and maintenance of the combination detector is critical for reliable operation: how to know it works — monthly test: press test button (1× per month), detector emits siren (85dB) → detector works. LED indicator: green LED flashes (every 30-60 seconds) → detector works, red LED → alarm (smoke or CO), yellow LED → battery low or sensor faulty. Battery notification: detector emits beep (every 30-60 seconds) → battery low → replace battery. When to replace — battery: replace battery every 1-2 years (9V or AA), replace battery when detector beeps. Smoke sensor: smoke sensor works 10 years → replace detector after 10 years. CO sensor: CO sensor works 7-10 years → replace detector after 7-10 years. Entire detector: replace entire detector after 7-10 years (CO sensor lifespan), date written on back of detector. Cleaning: clean detector 1× every 6 months (dust, cobwebs), use vacuum (low power) or compressed air. Recommendation: monthly test (press test button), cleaning every 6 months, battery replacement every 1-2 years, detector replacement every 7-10 years → reliable protection.
