Or will the resin harm the alginate?? Please ANY help on this topic
Most places require one in each bedroom and one in any hallway.
Depends on your local and state laws. Contact your city hall for rules regarding smoke detectors. Some states also require a Carbon Monoxide detector too.
Landlord/tenant laws depend on the country you live in
It depends on what you are talking about. Silver is the most reflective material you are likely to see. Copper reflects one wavelength of light at 100% efficiency. Plasma causes a lot of confusion because it reflects radar signals, causing random interference with measurements of albedo on other planets and asteroids.
Don't install smoke detectors in kitchens (near the stove) or bathrooms. Cooking fumes and moisture in the bathroom can set them off. Check with your local building code requirements. The minimum code requirements for my area is one in each sleeping area and the hallway and the top of any internal stairways. I have to have 7 installed. The reason you need one outside the bedroom door is that with the bedroom door closed, the fire can get a significant head start before enough smoke gets into the bedroom to set that alarm off. Make sure your tenants know that they are required to replace the battery(ies) 1x or 2x per year as they would if a light bulb went out.
