Fire and Smoke Alarms

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.

Smoke detectors commonly use the isotope americium-241. This radioactive isotope emits alpha particles, which help ionize the air in the sensing chamber, allowing the detector to detect smoke particles. When smoke enters the chamber, it disrupts the ion flow, triggering the alarm. Americium-241 is favored due to its relatively long half-life and effective ionization properties.

Every 5 years. There is a code on the top of the battery (or atleast most models have one) that indicated the date of manufacture. Go to that battery makers website on how to read the code. Sometimes it will look like 111209.

What are pull station clearence requirements

Usually, this indicates that the backup battery in the smoke alarm is low.

If your alarms are connected to each other (usually indicated by a third wire connected to the alarm), it can be tricky to re-integrate one once you disconnect it. It seems that when connected for the first time, the alarm trips all the other alarms connected to it. To re-integrate an alarm properly, you need to disconnect power to all units (usually via the main circuit breaker) add the new unit, and then reconnect power to all units simultaneously (just turn the switch back on again).

If you can replace the battery without disconnecting the alarm from its hardwired connection, that would save you a lot of headache. Sometimes the wires aren't very long which makes it challenging to replace batteries. If several alarms are beeping, it may be easier to disconnect them anyway.

so basically, in other words.....it means you need a new smoke alarm...duhh ahahah

Squeeze the sides.

You would simply need to keep the smoke away from the sensor, either by isolating it physically or by directing it away. Some sensors also do not detect very small amounts of smoke, so it could be sufficient to open a window and dilute the smoke with fresh air. However, some ionizing sensors can be set for extremely high sensitivity and will detect combustion byproducts almost instantly.

Yes, you should be able to change the company. Call up the company for more details in the process and it should work out fine. If you don't know which company to switch to, ask friends or family.

If a wall is deemed a "fire rated" wall then every penetration through it should be run through a "sleeve" or 3/4" EMT conduit, and filled with fire caulk associated with the fire rating of the wall.

An End of Line resistor is used to create a small constant load in a protective zone or loop.

The control panel monitors the current in the loop to detect if the wires have been cut open, or shorted, both of which would be either a "trouble" or "alarm" indication.

Probably dirty or needs a battery backup replaced. Vacumn it or blow air using "canned air". Change the battery every year or even twice a year.

Run away. Or try to put it out. if it gets on you drop to the floor and roll it out.

There is no difference. Edwards Systems Technology (EST) is was a part of GE Security Fire & Life Safety division, which was in turn sold to UTC. The contol panel product line, including EST2, iO Series and EST3, can be seen here: http://www.lamarcosystems.com/index.php?option=com_content&task=view&id=103&Itemid=158

GE is considered a leader in life safety technologies EST3 control panel is top of the line panel and is protecting the hotels, military bases, hospitals, high rise buildings and more around the globe.

No, the radioactive sources in smoke detectors emit alpha particles. These are very weakly penetrating and are stopped by a few centimetres of air, therefore the plastic casing of the detector is sufficient to stop any radiation.

What is the response time to a fire alarm system under the nfpa code book or life safety 101 code book.

Smoke Detectors use things called LDR's or Light Dependent Resistors which lose resistance with an increase in natural light. So when there is a fire, smoke blocks out the natural light, alarming the smoke detector with an increase in resistance. Once the smoke is gone the resistance decreases and a current is allowed to flow to shut down the smoke detectors alarm. :)

is a smoke detector like a sense organ

No, it can't take a picture of you. But it can spray ink on you, that will mark you. And probably your fingerprints will be on the alarm.

these are the loudest i have have heard:

1. simplex truealerts horn/strobes

2. simplex 4040s

3. gentex commander 3s

4. simplex 4051s

5. wheelock 7002ts

6. gentex gms

7. simplex 4263-10

8. federal vibratone 350s

9. simplex 4050s

10. wheelock mb g10 24r fire bell

I can only assume that you are attempting to connect 480VAC coil from a elevator to a fire system in order to shunt the elevator. In order to do this you will need a shunt trip breaker rated for this use.

Yes.

In the alarm panel box or an auxiliary box nearby.

The batteries are probably dead ! you should probably replace them and see if it stops! that could be dangerous :)
