Fire and Smoke Alarms

yes

They usually beep repeatedly, once every few seconds or once a minute to indicate the batteries are going dead. You should replace the batteries immediately.

Home security alarms are not cheap by any means, but the protection they provide is worth it. If you are looking into purchasing a home security system try visiting the ADT website to see what they can offer and if they have price ranges available.

Electrical and communications system receptacles on walls shall be mounted no less than 15 in (380 mm) above the floor. - ADAAG under section 4.27.3

i believe its once a month for schools.

Arizona has adopted the International Fire Code as its standard, with a few modifications.

Under 408.3.1, in Group E occupancies, the first school drill must be held within 10 days of beginning classes. Under 405.2, Group E (education) occupancies must hold drills monthly, with slight deviation permitted for inclement weather.

It probably beeps during the day too, but there is too much ambient noise in an active household to notice it. Change the battery and be done with it.

A fire alarm is usually the constant ringing of a bell or bells

Usually in high school fire drills, the fire bell sounds and the teachers tell the students to walk calmly in a single file line to the place of safety, usually a hallway or interior room with no windows or heavy filing cabinets. Then a principal or something comes on the PA and tells everyone it was just a drill and they can all go back to class.

Under US fire codes, all schools k-12 are required to hold monthly fire drills.

Yes Pay attention to the manufatures written instructions, any local code and the authority having jurisdiction . Most smokes can be located 8" down from the cieling. By locating it on a side wall this reduces the protected area. Per generally accepted code the detector location can only be 21 feet, maximum, from the furtherst location in the room. If on the cieling the coverage area is 15 feet from the nearest wall, 30 feet on center.

Tenants are not responsible for anything after they move out. A good landlord will replace batteries in smoke and carbon monoxide detectors every year, regardless of who is renting.

No, they are called Lie Detectors. Maybe Smoke detector might apply to their use by Fire Marshals investigating Arson suspects! not funny.

Smoke alarms have many different designs. A common one is powered by a single 9 volt battery but I have also seen ones powered by two AA cells (total 3 volts). Almost any voltage might be used that can be supplied by groups of common 1.5 volt dry cells connected in series.

You have to test it frequently, the reason is that smoke may be visible or may be not and you want to see all particles that emanate from any kind of smoke, specially during night time when you are asleep. Most of dust/ash particles may not be visible and via ionizing detector they will be!!!! Alarm will go off making alert sound and you will be safe.

So, sumirizing, you need to test ionizing smoke detector to see if sensor is in ok condition.

Yes, that's safer.

New electrical code regulations are moving that way. Check with your local electrical inspector to fine out what the regulations are in your specific area.

Resistor have a definite function in circuits and because every resistor disspates power, it is not included in the circuit without good reason. Some smoke detectors have electronic circuits in them, and these would have resistors, but it is not possible to be more specific.

Fire alarm system may be having some electronic devices and cards, in which some capacitors are used. Capacitors are part of any electronic cards.

It's usually americium-241. It undergoes alpha-decay with a half-life of about 400 years. Am-241 is artificially manufactured; it doesn't occur in nature.

that depends on how often you drive. best way to determine if brakes need changing, is to look at brake fluid resevoir. if level is low, your linings are worn and either need replacing or renewing

NFPA 72 recommends installing smoke detectors at the ceiling height of 4-12 inches depending on the specific area and application. However, some local codes and regulations may have specific requirements for the installation height of smoke detectors above a ceiling. It is essential to check with the local authority having jurisdiction for specific requirements in your area.

The fire alarm device is usually equipped with an Amercium-241 that is alpha emitter source together with a battery derived electric circuit. In the normal situation the alpha particles ionize the air causing circuit connection. However when there is a smoke the circuit is disconnected due to the smoke that acts as an insulator and hence the alarm is actuated.

On a 2002 Pontiac Grand Am: turn the key to the on position for 30 minutes or until the security light goes out. The car should start.

Does it happen only while the car is "off" or does it also happen while driving? If the alarm happens without any apparent reason, even while driving, you may want to check the anti-theft relay. If alarm happens while the car is off, it could be a problem with any of the various switches and sensors that sense alarm conditions.

Many smoke detectors use Americium-241, which emits alpha rays, to keep air ionized.

My keyfob says Quantum. I believe its a rebadged scorpion
