Hearing Impaired Fire Alarms — Visual and Vibrating Systems in Tbilisi
Hearing Impaired Fire Alarms (Deaf Smoke Alarms) are specialized safety systems that provide protection for deaf and hard of hearing people during fire using visual (powerful strobe light) and tactile (vibrating pads) signals that don't depend on audible siren in Tbilisi and throughout Georgia. These systems are essential for hearing impaired people, especially during sleep when hearing aids are removed, and provide equal safety for all people, making them absolutely necessary for residential houses, apartments, hotels, hospitals, schools, and any type of public buildings where hearing impaired people live or work. LAGI offers full range of hearing impaired fire systems: strobe sirens (ultra-bright LED, 177 candela, white/red flash), vibrating pads (under bed, 12V DC, adjustable intensity), combination systems (strobe + vibration + siren), wireless interconnectable systems (RF 433MHz, all devices synchronized), text display panels (LCD screen, text messages), smart systems (Wi-Fi, smartphone notifications, smartwatch vibration), fire panel integration (addressable/conventional). All systems comply with ADA (Americans with Disabilities Act) and EN 54 standards.
Main Components of Hearing Impaired Fire Systems
- Strobe sirens — ultra-bright LED, 177 candela intensity, white/red flash at 1Hz frequency, 360° visibility, ideal for bedrooms, corridors, public spaces.
- Vibrating pads — under bed placement, 12V DC power, adjustable vibration intensity, wakes even in deepest sleep, ideal for bedrooms, hotels.
- Combination systems — strobe + vibration + siren (85dB), three signal types simultaneously, maximum effectiveness, ideal for home use.
- Wireless interconnectable systems — RF 433MHz connection, all devices synchronized (smoke detector → strobe → vibration), no wiring needed, simple installation.
- Text display panels — LCD screen, text messages ("Fire in kitchen", "Smoke in bedroom"), precise information, ideal for large buildings.
- Smart systems — Wi-Fi connection, smartphone push notifications, smartwatch vibration, remote monitoring, Alexa/Google Home integration, ideal for young hearing impaired.
FAQ — Frequently Asked Questions
Standard fire alarms use only audible siren (85dB) which is not effective for hearing impaired people, especially during sleep. Problem: 1) deaf people can't hear siren. 2) hard of hearing people remove hearing aids during sleep and can't hear siren. 3) in deep sleep siren may not wake. Solution: hearing impaired fire systems use: 1) visual signals — ultra-bright strobe light (177 candela) that flashes and wakes person. 2) tactile signals — vibrating pad under bed that vibrates strongly and wakes person. 3) text messages — LCD screen or smartphone notification that precisely tells what's happening. This provides equal safety for all people.
Vibrating Pad (Bed Shaker) is small device placed under bed or under pillow that vibrates strongly during fire. How it works: 1) smoke detector detects smoke and sends signal (wireless RF 433MHz or wired connection). 2) vibrating pad receives signal and starts strong vibration. 3) vibration transfers to bed and wakes person. 4) vibration continues until person turns off or until fire is extinguished. Effectiveness: studies show vibrating pad wakes 95%+ hearing impaired people including in deep sleep. This is most reliable method for hearing impaired. Adjustable intensity allows customizing vibration to individual needs.
Correct strobe siren placement is critical for effective warning. Recommendations: 1) in all bedrooms — strobe must be in all bedrooms where hearing impaired person sleeps, on ceiling or wall in direct view from bed. 2) in corridors — strobe in all corridors along evacuation route. 3) in common spaces — strobe in kitchen, living room, bathroom. 4) height — 2.4-3m height on ceiling or upper wall, 360° visibility. 5) intensity — minimum 177 candela for bedrooms (ADA standard). 6) flash frequency — 1Hz (one flash per second), white or red light. 7) synchronization — all strobes must flash synchronously (not opposite to each other). Important: strobe alone is not sufficient for bedrooms — must add vibrating pad.
