Fire and Smoke Alarms

Hard-wired "home" type smoke detectors can not be adjusted for sensitivity. Detectors that appear "too" sensitive are usually very dirty or located in the wrong place. Carefully review the lengthy instructions that come with each detector with regard to selecting a location. Avoid: high air velocity areas such as near air conditioner vents, areas outside bathroom doors where steam vapors waft out, kitchen areas where the cooking smoke can get to the detector before disapaiting Studio apartments pose an obvious problem. You can try cleaning the detector to make it less sensitive by following the manufacturer's cleaning instructions, but when in doubt, replace it. Isn't your life worth $10.00?

Pushmatic breakers are known to have a higher failure rate compared to modern circuit breakers, which could potentially pose a fire hazard. It is advised to consider replacing them with newer, more reliable circuit breakers for improved safety and peace of mind. Consulting with a professional electrician is recommended to evaluate the condition of the breakers and determine the best course of action.

Jan Van Der Heyden used leather and canvas to invent the first fire hose in the late 17th century. He developed a more effective way to deliver water to extinguish fires by using these materials to create a flexible and durable hose.

Style Y is a designation of circuit performance under different states of the circuit. For example: an initiating circuit and a NAC circuit may both be class B, with a panel on one end of the circuit and a resistor on the other. If there is an open on either circuit (the panel doesn't see the EOL), then a trouble is initiated at the panel. However, if there is a short between the two wires on a circuit, the panel will react very differently on the initiating circuit than it will on the NAC. Style Y means that the fire alarm panel will display a trouble on either an open or a short on the NAC circuit, where style 4 means that the Initiating circuit will generate an alarm on the panel in the event of a short, and a trouble in the event of an open.

A fire alarm test can run for hours, depending upon how many sensors, pull stations and annunciators there are, among other things.

A self-contained smoke alarm should be tested for at least 30 seconds, to determine if the battery has enough power to keep the sound steady for that time, or if the battery is weak and the sound quickly tapers off.

Intentionally damaging or tampering with a fire alarm system can be a criminal offense in many jurisdictions. The severity of the consequences, including whether or not you may go to jail, would depend on local laws and the specific circumstances surrounding the act. It is important to refrain from interfering with fire safety equipment and to report any issues to the appropriate authorities for proper handling.

It depends upon the contract, but generally you cannot remove anything permanently installed in anyone else's property unless you have a court order.

In a typical payment dispute, a contractor would place a lien on the property, as a means of securing future payment, then negotiate a payment plan with the debtor, or take them to court for an order of payment and possible seizure of other property.

Others have said:

Yes, you can remove devices but it will add to your cost and would not be cost beneficial. However, you have to use other means.

Yes, smoke alarms are safe when used properly. They are designed to detect smoke and alert occupants to potential fires in the home, providing valuable time to escape. It's important to regularly test and maintain smoke alarms to ensure they are in proper working condition.

Smoke alarms are designed to be loud in order to alert people to potential danger and ensure they hear the alarm even if they are asleep or in another part of the house. While the high decibel level may be uncomfortable or even painful, it is necessary to grab attention and prompt immediate action in case of a fire. The priority is to ensure people's safety by making sure they can hear the alarm even in noisy or chaotic situations.

This could be general smoke alarms installed in you house. This could also be a full functioning fire alarm system. Where you have call points, smoke/heat detectors, bells/sounders/strobes etc. This would be connected through a control panel. SOme intruder alarm systems also facilitate smoke detectors and act as a fire alarm system as well as an intruder alarm system.

Or you could make your own fire alarm. With a light switch, call point, smoke/heat detector with a low voltage (12-24 Volts) power adapter/batteries. Although this could not be very reliable. So try and go for the options above.

Bugs are not specifically attracted to fire alarms per se. However, they are often attracted to sources of light and heat, which may include fire alarms that have LED lights or emit a low level of heat. Bugs may mistake the light or heat from the fire alarm for a potential food source or a safe shelter, leading them to congregate around it.

The type of cable commonly used for fire alarm systems is called "fire-rated cable" or "plenum-rated cable." This type of cable is designed to meet the fire safety standards and building codes for fire alarm system installation. It has a fire-resistant jacket that helps prevent the spread of fire and toxic smoke in the event of a fire.

Creating a homemade fire alarm system powered by a homemade battery is not recommended. Fire alarms are critical safety devices that require reliable power sources to ensure they function properly in case of emergencies. It is safer to use commercially available fire alarm systems that are tested and certified for reliability and performance.

That's probably a safety feature. If you have a forced air system it can blow smoke and embers all over the building in a fire, causing health and damage concerns. By disabling the heating system during a fire the furnace will not actively spread the fire. You may want to contact the installer to verify this. What kind of thermostat are we talking about? built-in to a window unit or on the wall for central AC? Is it a residential or commercial system? If a wall mount thermostat, is it with a clock? electronic or mechanical? When you say fire alarm, do you mean a commercial fire alarm or the smoke detectors in your home? If in your home, are they hard wired or battery only?

Hi,

They take the little 12v batteries, same as for hand held digital camera's.

The ability towards cleaning smoke damage depends upon the items composition and if any heat damage hinders restoration.

Common items restored via smoke are paintings, ceramics, fabrics, photos and furnishings all taking great care not to further damage surface composition.

Common ways are airing out, peroxides, absorbing powders or compounds, mild chemical solutions these should be done via a trained professional that can grade if smoke cleaning or the method used won't damage the items one desires to restore.

The items use vary and some are close held professional trade secrets utilized fire restoration especially for high valued antiquities. As many absorbing compounds or chemicals used are customized blends specific towards the item restored and how it will be rendered used after restoration.

Smoke alarm batteries are easy to replace, once you find where they go. The design varies from brand to brand.

Usually, the battery is located on the side of the alarm, either in a "drawer" or a swinging compartment. There may be a small plastic latch holding it closed. Occasionally, it is necessary to remove the alarm from the wall or ceiling to find the battery compartment. This can be done by rotating the entire alarm counter-clockwise until it releases. The battery compartment is designed not to close if the battery is inserted incorrectly.

Many smoke alarms have an option to permanently screw the battery compartment closed. This is typically done in rental units to prevent tenants from removing the battery during a false alarm. In this case, the landlord is required by law to change the battery. If you are the landlord, consult the alarm documentation (which can be found online) for instructions on how to remove the locking screw.

Nobody knows exactly how long any particular smoke detector may last, but there are national fire codes that require you to replace them no less than every ten years, meaning that everyone HOPES they last at least ten years.

A system that blocks unwanted connections/communication based on certain filters.

Basically, it can deny NAT redirects, multicast, java applets, cookies, PPtp, PPoE, etc.

Also, blocking access to certain web pages by domain name/ keywords is possible.

Let's say you tried to access runescape

The firewall is set up to block any URL with "runescape" in it.

So the firewall will display a page in your browser saying "access denied" or "forbidden."

So yeah. A firewall can block communications based on their content.

Works for both incoming and outgoing.

An audible sound or a visual device that operates when a fire alarm is activated. Audio devices may include speech systems, sirens, sounders bells etc. While visual devices may be strobes.

1. Smoke detectors work in two different ways, they are ionisation and photoelectric.
2. The ionisation uses americium 241, a radioactive element, which gives off particles with an electric charge. These turn air molecules in the chamber into ions (charged atoms). These in turn buzz between two metal electrodes, allowing electricity to flow around the circuit. When smoke particles enter the chamber, they neutralise the ions and stops the current. The electronic circuit detects this and triggers the alarm.
3. The photoelectric way is a bit simpler as it uses a LED the emit light and when smoke particles are present is deflects the particles to the photocell generating electricity and setting of the alarm.
4. So smoke detectors don't detect smoke, they detect the alpha particles emiting radiation!
5. if you are doing this as a project, DO NOT COPY, YOU WILL GET A FAIL IF YOU DO THAT :O !!!
6. Instead try and take bits out!

Isn't it obvious...

Comparison charts such as the attached link will allow you to compare brands side-by-side and make an informed decision.

In the UK it is not compulsory to have a smoke alarm at home, though it is advisable.

In the USA, national fire codes require smoke alarms in all new construction of dwellings, including a smoke alarm in each sleeping area, outside the sleeping area and on each separate level of the dwelling.

Existing structures may be exempt unless they are rented for money, or undergo any major building upgrades (terminating any "grandfathered" exemption).
