PIR Detectors — Combined Security in Tbilisi
PIR Detectors (Passive Infrared Detectors) are multifunctional sensors that combine motion detection and temperature change monitoring in one device — provide object protection both from intrusion (motion detection) and from fire (rapid temperature rise detection) in Tbilisi and throughout Georgia. These detectors are ideal for homes, offices, warehouses, and facilities where dual protection is required — one sensor performs functions of two systems (security alarm + fire alarm). LAGI offers PIR detectors with full functionality: motion detection (12m range, 90-110° angle), temperature monitoring (rapid rise detection 8-10°C/min), Pet Immunity function (ignores pets up to 15-25kg), Anti-Masking technology (masking attempt detection), wired/wireless models, IP54 protection, integration with security and fire panels. All models comply with EN 50131 and EN 54 standards.
Main Functions of PIR Detectors
- Motion detection — infrared sensor detects human movement in 12m range, 90-110° angle.
- Temperature monitoring — detects rapid temperature rise (8-10°C/min), early fire warning.
- Pet Immunity — ignores pets up to 15-25kg, no false alarms.
- Anti-Masking — detects masking attempt (if someone tries to cover sensor).
- Dual protection — one sensor = security alarm + fire alarm.
- EN 50131 + EN 54 — complies with both security and fire standards.
FAQ — Frequently Asked Questions
PIR (Passive Infrared) detector uses infrared sensor that detects human body heat — when person moves in sensor range, sensor detects infrared radiation change and triggers. Difference with regular motion sensor: regular PIR sensor — only motion detection, used in security alarm. Fire PIR detector — motion detection + temperature monitoring, detects rapid temperature rise (early fire sign), dual protection.
Pet Immunity (pet ignoring) is technology that allows having pets (dog, cat) without false alarms — sensor uses special algorithm that distinguishes infrared signature of human and animal. Pet Immunity 15kg — ignores pets up to 15kg (small dogs, cats). Pet Immunity 25kg — ignores pets up to 25kg (medium dogs). Important: Pet Immunity not 100% guarantee, large dogs or multiple animals simultaneously may trigger sensor.
Yes, PIR detectors integrate with both systems — detector has two outputs (Relay Output): output 1 — security alarm (motion detection), connects to security panel. Output 2 — fire alarm (temperature rise), connects to fire panel. This allows dual protection with one sensor — at night works as security sensor, 24/7 works as fire sensor. Economy — no need for two separate sensors.
