WebUnder UL test conditions, ionization detectors consistently respond about 30 to 90 seconds faster to open or “fast-flame” fires than photoelectric smoke detectors. However, ionization detectors respond on average between 15 to 50 minutes slower in a smoldering fire than photoelectric detectors. WebOptical smoke alarms work via an infra-red LED which sends out a pulse of light into the units sensor chamber every 10 seconds. If smoke enters the chamber, it causes light to be scattered across the internal receptor which in turn causes a signal to be sent to the integrated circuit that triggers the alarm.
