First alert carbon monoxide detector2/29/2024 ![]() ![]() Given those stats, it’s easy to see why Keenan told us that “resident behavior is the biggest challenge we face with smoke alarms.” This is also the reason the International Association of Fire Fighters, the largest firefighter union in the world, supports legislation (PDF) making photoelectric alarms a mandatory requirement for fire and building codes. The First Alert CO400 Carbon Monoxide Alarm utilizes an electrochemical carbon monoxide sensor that lasts for up to five years to detect carbon monoxide. Choose from many types like Carbon Monoxide Detector, smoke carbon monoxide. A study of smoke alarms in rural Alaskan homes found an “8-fold higher incidence of nuisance alarms in homes with ionization alarms.” In addition, the same study found that, due to nuisance alarms, “ionization smoke alarms were almost 5 times more likely to be disconnected 6 months after installation compared with photoelectric alarms.” A 1995 Texas A&M study (PDF) that took into account disabled alarms concluded that “the probability of a fatality due to the failure of the ionization detector to detect a flame ignition fire is 19.8%.” With photoelectric detectors, that number dropped to 3.99%.

The First Alert GCO1CN Combination Explosive Gas and Carbon Monoxide Alarm with Backlit Digital Display offers reliable detection of three common household threats: methane, propane, and carbon monoxide. Carbon Monoxide Detector: First Alert SC0501CN-. First Alert GCO1CN Combination Explosive Gas and Carbon Monoxide Alarm. Ionization sensors offer optimal smoke detection from flaming fires. The First Alert CO400/SA303 Smoke and Carbon Monoxide Detector Combo Pack features ionization smoke-sensing technology with a contemporary enhanced smoke-gathering design. ![]() Research backs Keenan up on the problem of disabled alarms. alarms, combination smoke and carbon monoxide alarms, battery operated and hardwired alarms.
