Combination Smoke and Carbon Monoxide Detectors | CMDP

Combination Smoke and Carbon Monoxide Detectors. I have long advocated against the use of combination alarms because the most effective position for a smoke alarm is typically on the ceiling, while carbon monoxide detectors are usually best mounted at about eye level on a wall. However the growth in popularity of combination smoke and carbon ...

Smoke Alarms and Carbon Monoxide Detectors: What You …

May 31, 2021· Smoke detectors employ one of two technologies to detect fires: the photoelectric effect and ionization, and dual-sensor alarms use both. The sensor in a photoelectric smoke alarm consists of a semiconducting plate and a beam of light that is shining at an angle with respect to the plate. When smoke enters the sensing chamber and deflects the light toward the plate, a small voltage is ...

What are Dual Sensor Smoke Alarms? (with pictures)

Dual sensor smoke alarms should have the battery replaced twice a year. The innards of a dual sensor smoke alarm include a photoelectric sensor and an ionization sensor. Photoelectric sensors are very good at detecting slow, smoldering fires like fires which start in mattresses, couches, carpeting, and drapes. An ionization sensor can detect a sudden burst of flame like a grease fire.

Smoke Detector Vs Carbon Monoxide Detector (Which One Do ...

Carbon monoxide detectors have 3 different types of sensors that set off different types of alerts. According to Biomimetic sensor: a gel changes color when it absorbs carbon monoxide, and this color change triggers the alarm. Metal oxide semiconductor: When the silica chip’s circuitry detects carbon monoxide, it lowers the electrical resistance, and this change triggers the alarm.
