Advanced Multisensing Photoelectric Technology
EA-318 Series optical smoke detectors and multisensors
EA-318 series optical smoke detectors are designed to respond to a wide spectrum of fires and ease installation. The EA-318 series multisensors use Advanced Photoelectric Technology in conjunction with the 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.
