Some brands of wireless smoke detectors include First Alert, Kiddle, OneLink, and V-Plex. Of these brands some also include the option of voice controlling. While other include a hardwired option for providing constant power.
I think it is a great idea to research smoke detectors to find the best one for you. The brands available vary from country to country, but if you have a look at this site it will give you some good comparisons. http://www.consumersearch.com/smoke-detectors
You can recycle smoke detectors at certain electronic waste recycling facilities or through mail-back programs offered by some manufacturers.
There are two smoke-sensing technologies commonly used in residential smoke detectors: photoelectric and ionization
To properly dispose of Kidde smoke detectors, you should contact your local waste management facility or recycling center to inquire about their guidelines for electronic waste disposal. Some facilities may accept smoke detectors for recycling, while others may require you to dispose of them in the regular trash. It is important to follow these guidelines to ensure the safe and environmentally friendly disposal of the smoke detectors.
Americium is primarily used in smoke detectors to detect smoke by ionizing air particles. It is also used in some medical devices for radiation therapy and in some industrial measurements for material analysis.
Photo-electric (PE - as opposed to the ionization type of) smoke detectors do indeed use the reduction of light energy at the receiving end to "Sound The Alarm". Whether or not this is IR energy, I can't say. Might someone else please fill this in? Thanks.
Some brands of wireless TV headphones would be Sony, Jabird, or Sennheiser. The headphone will depend on whether you have a digital or analog connection on your TV.
In several households and commercial establishments, it is easy to overlook that a small quantity of radioactive substance (Americium-241) is present in ionization-type smoke detectors, which should be treated with caution once a detector is at the end of its life-cycle. The following is a straightforward, practical guide for disposal: Examine the unit label: If you see a symbol for radiation and the words "Americium-241" or the letter "I", for ionization-type smoke detector, it must be disposed of in accordance with rules that apply. Remove the battery: Take out the battery meant for backup use and recycle it separately if permitted through your local facility, (and see if they accept batteries for recycling).Product Care Recycling. Return to the manufacturer: Many companies allow you to arrange for a mail-back program so disposal of the unit can be coordinated with the manufacturer's plan/location for safe disposal. In the absence of a product program: In some areas, the product can go in regular trash, as long as you do NOT put it in a regular recycling bin. Document the rules and check with local disposal: Every area, city, even neighborhood has their own waste/recycling local authority rules, so check with the authority. For any organization that buys facility related equipment (including safety and recycling equipment), there are organizations like Pepagora that can assist with finding verified suppliers and compliance rule guidelines. ⚠️ Be advised: Do not try to take apart or tamper with
Americium (241) is used in smoke detectors that use "ionizing radiation" to detect changes in the air. Other types of detectors use photo-electric sensors based upon a variety of photo-sensitive chemicals.
There are many levels of long range motion detectors, personal use and commercial use. Some motion detectors can detect movement up to 8-10 miles away. Some good brands for long range motion detectors are Honeywell and KNX.
The actinide used in some smoke detectors is americium-241. It emits alpha particles, which ionize the air inside the detector, causing a small electric current to flow. When smoke enters the detector, it disrupts this current, triggering the alarm.
There are many reliable brands for wireless speakers. Some of them are: Bose, Sonos, Rocketfish, Beats, Samsung, Jabra, iHome, Logitech, Jawbone, and JBL.
