Alarm Sirens — In Tbilisi
Alarm Sirens are the executive components of security alarm systems that receive a trigger signal from the control panel and emit a loud audio signal (110-120dB) when intrusion detectors, fire sensors, or panic buttons activate, alerting the owner, neighbors, and passersby in Tbilisi and throughout Georgia. These devices are the critical link between PIR motion detectors, door/window magnetic contacts, and the control panel — the sensor detects intrusion → the panel triggers the siren → 110-120dB audio + LED strobe scares the thief, warns the owner, and wakes the neighbors. LAGI offers a full range of industrial-grade sirens: indoor wired sirens (12V DC, 110-115dB, piezoelectric, IP30-44), outdoor wired sirens (12V DC + battery backup, 115-120dB, electromagnetic horn, LED strobe, anti-tamper, IP54-65 weatherproof, anti-vandal steel/polycarbonate housing, UV-resistant), wireless 433MHz sirens (learning/rolling code, 1-2 year battery, easy panel pairing), wireless 868MHz sirens (Grade 2/3 Ajax/Yale/Hikvision ecosystems, AES 128-bit encryption, two-way monitoring), programmable tones (alarm/fire/chime/aux), connection to NO/NC panel output. All models comply with EN 50131 Grade 2/3 standard.
Main Types of Alarm Sirens
- Indoor wired sirens — 12V DC, 110-115dB, piezoelectric element, compact design, IP30-44, connects to panel SIREN output, ideal for apartments and small offices.
- Outdoor wired sirens — 12V DC + battery backup (6-12 hours), 115-120dB, electromagnetic horn, LED strobe, steel anti-vandal housing, IP54-65, UV-resistant, operation -25°C to +60°C.
- Wireless 433MHz sirens — RF link to panel (learning or rolling code), battery powered (CR2032/9V, 1-2 years), easy installation (no cable pulling required), range 80-150m in open space.
- Wireless 868MHz Grade 2/3 sirens — Ajax/Yale/Hikvision ecosystems, AES 128-bit encryption, two-way monitoring, jamming detection, 3-5 year battery, EN 50131 certified.
- LED strobe / flasher — red or blue flash 1-3Hz, visual signal for noisy environments and hearing-impaired users, housing-integrated or separate module.
- Programmable tones — alarm (continuous 3.0 kHz), fire (pulsing wail 500-1200 Hz), auxiliary (gas/water/panic), chime (doorbell), tone selected by DIP switch or panel configuration.
FAQ — Frequently Asked Questions
The choice depends on site type and installation complexity. Wired sirens (12V DC) — constant power from panel, no battery replacement needed, cheaper (30-80 GEL indoor, 80-180 GEL outdoor), most reliable, but require cable pulling from panel to siren (difficult in existing buildings). Ideal for: new construction, major renovation, new alarm systems. Wireless 433MHz sirens — battery powered (1-2 years), learning or rolling code for panel pairing, easy installation, price 60-120 GEL. Wireless 868MHz (Grade 2/3) — professional ecosystems (Ajax, Yale, Hikvision), AES 128 encryption, two-way monitoring (panel "sees" that siren is alive), jamming detection, 3-5 year battery, price 180-450 GEL. Recommendation: new site → wired (economical), existing apartment/house → wireless 433MHz (simple), high-security site → Grade 2/3 868MHz (cryptographic protection).
Decibel selection depends on location and site size — measured at 1 meter distance. Indoor siren: 95-105dB — sufficient for 1-2 room apartment (sound reaches neighbors through thin walls), 110-115dB — 3-4 room apartment or small office (sound reaches all rooms through closed doors), 115dB+ — large house or 200m² office. Outdoor siren: 110dB — villa, garage, small shop (audible within 50-100m radius), 115-120dB — large house, warehouse, commercial site (audible within 100-200m radius), 120dB+ — industrial site, open territory. Note: every +6dB = doubling of perceived loudness, sound power drops by 6dB with each doubling of distance (at 10m 110dB → at 20m ~104dB → at 40m ~98dB). Regulations: in Tbilisi residential zones, noise >85dB during night hours is restricted, but alarm activation is allowed as an exception (emergency situation).
Wired siren connects to the panel with 4 cables (2×0.75mm² or 2×1mm² 2-pair cable) — 1) +12V (red) — to panel SIREN+ output, 2) GND (black) — to panel SIREN- or GND, 3) TAMPER (yellow/green) — to panel TAMPER zone (NC contact, opening the siren housing → alarm), 4) BATTERY (blue, outdoor sirens only) — internal battery monitoring. Activation: panel activates the +12V SIREN output → siren emits 110-120dB audio + LED strobe. Time limit: panel typically cuts off the siren after 3-15 minutes (regulatory cut-off, to avoid disturbing neighbors at night). Power reserve: outdoor sirens have an internal battery for 6-12 hours (if burglar cuts panel power → siren still works). Panel programming: zone-to-siren mapping (which zone activation → which tone), tone selection (alarm/fire/chime) via DIP switch or panel menu, volume adjustment (low/medium/high).
