The Series 65 Optical Smoke Detector uses light sensing technology to “see” smoke entering the chamber. The external detector moulding is identical to that of the ionisation detector, and has an indicator LED which is clear in quiescent state and produces a red light in alarm. Responds well to slow-burning, smouldering fires.
Ionisation and optical smoke alarms

WebIonisation smoke alarms were very effective for detecting fast-flaming fire. Historically, ionisation smoke detectors have been recommended for landings and office spaces, but the technology behind optical smoke alarms has now advanced to the point that they … Web22 apr. 2024 · Smoke alarms are categorised into ionisation alarms, photoelectric alarms and dual detectors, which combine technologies of both types. Ionisation smoke alarms are better at responding to fast-flaming fires, while photoelectric alarms are more responsive to slow smouldering fires.
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. WebThe four types of fire detectors are heat, optical (ionisation), photoelectric, and ionisation/photoelectric. The differences in each of these are how they detect fires, heat being from temperature, and the other three being from smoke. The best detector is the …
WebThese smoke detectors with an alarm will quickly identify smoke which would indicate that there is a fire nearby, and gives off a loud signal to warn of danger, giving you enough time to escape and call emergency services.
