Optical Smoke Detectors and Multi-sensors

EA 318 series optical smoke detectors are designed to respond to a wide spectrum of fires and ease installation. The EA318 series multisensors use Advanced Photoelectric Technology in conjunction with a fixed temperature heat sensor to further extend its capabilities as a smoke detector. Every unit is individually tested and calibrated to ensure high reliability and prevent false alarms.
