alarms for homes

Because of its nature, the ionization sensor tends to be more sensitive at detecting small particles, therefore more often triggering false alarms. The First Alert 2 in 1 steered clear of the ionization sensor and only went for the photoelectric type. The photoelectric sensor is better suited at detecting larger particles usually from smouldering fires, that don’t erupt immediately into flames by using a light beam inside the detector which doesn’t directly hit the sensor, but will do so in case smoke enters the device and forces the light towards the sensor. Besides the smoke detecting sensor, the First Alert 2 in 1 also has a Carbon Monoxide Electrochemical sensor which has the role of detecting any rising levels of CO inside the room and triggering the alarm when the concentration crosses the safety levels there will be both visual and audible signals – up to 85dB at around 10 feet. If the sensor detects increasing levels of Carbon Monoxide, the CO LED will flash a red colour and the audible alarms will have the following pattern: four beeps, then pause, four beeps and then pause. Otherwise, if the sensor detects smoke in the room, the Power/Smoke LED will flash a red colour, while the audible alarm will beep three times, pause and again three beeps and pause.
