Fire and Smoke Alarms

There is no standard height but they are generally mounted at eye-level or above, to deter juvenile vandalism.

A recent survey of convicted thieves shows that 90% of burglars are deterred by yard signs and decals from home security companies. Measures outside your home, such as cameras or motion detectors seem to be more important since many thieves won't be scared off once inside your home.

This type of smoke detector is more sensitive. It uses a laser diode in the sensor instead of an LED which allows it to be much more sensitive.

A resistor in a sensor circuit is used as a simple way to monitor the function of the circuit. The resistor has a calibrated and known voltage drop and current while the circuit is "normal". If there is a short-circuit, or an open-circuit, the voltage and current will change and trigger the trouble alarm.

Polarity is switched in a fire alarm panel to ensure proper functioning of the alarm system and to provide a failsafe mechanism. This switching can help prevent false alarms and can also indicate wiring issues, as devices may not operate correctly if wired with the wrong polarity. Additionally, some sensors and devices are designed to work with reversed polarity, allowing for more flexible installation options. Overall, this practice enhances the reliability and safety of the alarm system.

I recommend you called the people who installed the driveway alarm from you. You do not want to risk the safety of your home because you had to fix things yourself.

Radiation is a physical property of matter. Under normal conditions, radiation occurs at a quantified, predictable rate. (This is why atomic clocks are so good at keeping time.) Radioactive isotopes in smoke detectors allow simple counting mechanisms to be used.

However, it is very expensive to isolate or synthesize certain radioactive isotopes, and beta and gamma radiation can be very dangerous as they ionize molecules in your body.

Relatively harmless compounds may decay into much more dangerous radioactive isotopes. This is why uranium can be handled with normal precautions but "spent" nuclear fuel is so harmful. Spent nuclear fuel contains isotopes of cesium, iodine, and plutonium that decay much faster and release beta and gamma radiation.

They are devices that are made to sense changes in heat (heat alarm/fire alarm) which then activated either self sounders or complex alarm systems

Smoke alarms detect chemical changes and as like heat set off either internal sounders or complex alarm networks

Should be a small fine can be anywhere from 50-500 dollars.

Probably not, but I recommend to avoid any contamination; it is more sure to recycle all defect, used smoke detectors in a special facility.

You should never ignore it.

Remove the batteries from the back of the detector.

Are you referring to the circuit supplying power to the control panel or the initiation/notification branch circuits controlled by the fire alarm system? The ampacity of the fire alarm control panel would determine the circuit size of the branch circuit supplying power to the control panel and the terminal on the control panel and fire alarm device would detrmine the size of conductor that it will accept. Most fire alarm control panels would require a minimum 15 amp circuit. The minimum conductor size allowed per the NEC would be 14 AWG. 22 AWG. is the smallest conductor that most control panels and device terminals will accept. These are considered Power Limited circuits.

A normal fire alarm needs the brass on top of the iron, however, in the frost alarm you will need to swap both of these metals, by putting the iron on top of the brass so when the temperature is too low, the circuit is open.

No! You can't hang or obstruct a fire alarm pull station at any time. To do so would mean you are breaking Health & Safety Regulations (and would probably invalidate your insurance, should there be a fire).

Freeze alarms work by calling a phone number that you program in to it when the temperature in your home or business drops below a certain temperature.

One can purchases an alarm system from many places. The most popular places to purchase alarm systems are: ADT, Home Security Store, Amazon, and eBay.

No, the fire alarm was invented by Francis Robbins Upton. There is no evidence that Thomas Edison ever contributed to this invention.

Complain to the landlord and they should be able to kick the family out. The police should be called everytime it is done.

The parents are responsible for their minor child so you could press charges of anti-social behaviour on them. If the fire department have been called out each time then ask them to involve the police too.

If the smoke alarm lasts for ten years before you need to replace it, and the batteries should be replaced at least once per year, you would need to change the batteries of a smoke alarm ten times before you replace the entire thing.

Window alarms can be purchased at many different home improvement retailers such as Home Depot and Lowe's. Retailers such as Sears, RadioShack, Staples, and Walmart also carry window alarms.

A residential smoke alarm must be at least 75 dBA, or 15 dBA above average ambient sound (whichever is greater), measured at pillow location, meaning that it may be much louder at the source.

In a "high ambient noise area" it must be 110 dBA.

Yes. The latest technology Smoke detector IP cameras are integrated with both functions of smoke detector and IP camera. It helps to monitor your home or office from any part of the world. It can be connected to a WiFi network and when a motion is detected, it will send the live videos and images to User's mobile or computer.

One of the least expensive investments that you will make in your home could ultimately prove to be the most valuable. Home smoke alarms are essential to possess in various spots through the dwelling to ensure the greatest protection.

When selecting placement areas, consider putting smoke alarms in areas of high risk, such as the kitchen and garage. Each individual room should posses its own device, and any hallway or stair areas should have their own smoke detectors, too. Most importantly, check the batteries every three weeks to ensure they are functioning properly.
