The main difference between a photoelectric smoke alarm and an ionization smoke alarm is the way they detect smoke. Photoelectric alarms use light to detect smoke particles, while ionization alarms use radioactive particles. Photoelectric alarms are better at detecting smoldering fires, while ionization alarms are more sensitive to fast-flaming fires.
Prisons use burglar alarm systems to help keep inmates from entering sensitive areas of prisons. They are used to control the movements of inmates while they are incarcerated.

A touch alarm is a type of alarm system that is activated or deactivated by touch. It typically involves a touch-sensitive interface that allows users to set or disable the alarm by touching a specific area or button on the device. This type of alarm can be found in alarm clocks, security systems, and other devices that require manual activation.
When the LED light on an aftermarket alarm stays on, it means that the alarm is active. The light generally shows that the alarm status is "ready."
Yes, they are sensitive to light.
It depends on what kind of alarm you have. For my alarm, a red light is on.

An ionization smoke alarm is a type of smoke detector that uses a small amount of radioactive material to ionize the air inside the alarm chamber. When smoke enters the chamber, it disrupts the ionization process, triggering the alarm. This type of smoke alarm is more sensitive to fast-burning, flaming fires, but less sensitive to slow, smoldering fires. In comparison, photoelectric smoke alarms use a light beam to detect smoke particles, making them more effective at detecting smoldering fires. Dual-sensor smoke alarms combine both ionization and photoelectric technologies for comprehensive fire detection.
To reset an alarm on your iHome, first, press the "Alarm" button to access the alarm settings. Use the "+" or "−" buttons to adjust the time or to turn the alarm off. If you want to set a new alarm, after adjusting the time, press the "Alarm" button again to save the new settings. Finally, ensure the alarm is activated by checking the alarm indicator light.
To set the alarm on your iLuv, first, press the "Alarm" button on the device. Then, use the "+" or "-" buttons to adjust the hour and minutes for the alarm time. Once set, confirm by pressing the "Alarm" button again, and ensure the alarm indicator light is on. Finally, adjust the volume if needed, and your alarm is ready to go!
