What is the advantage of Addressable Fire alarm on the Conventional one??

With Conventional system you get information about tye Alarm Zone Number (Which may contains many detectors) But With the addressabe system you get the Zone number and exactly which the detector activated the alarm which is more accurate.

I don't know that the burglar alarm can be attributed to any single inventor.  ADT is the oldest alarm company in the United States.  Their web site includes a history of the company back to the 1800s.\n\nhttp://www.adt.com/adt/about_adt/company_history/

the windows xp firewall is limited as its only 1 way protection therefore not good.\nthere are some free firewalls, zone alarm has a free one also a paid for pro version which has a few more things added. \nits the best firewall to get.\nnorton and mcafee are good but not the best options.

Contrary to popular belief, most agencies now scramble their radio transmissions and you may end up getting only the Fire department. \n\nAren't we terrible? \nWe have to keep the bad boys from hearing when we are coming for them.

The factory alarms are documented in the manufacturers literature.  The home-made alarms are all different from each other and reflect the intellect, personality and experience of the installer.  Some alarms are silent in order to provide a better opportunity to catch the thief.\n\nThe best way to learn about alarms?  Install a variety of different alarms on different cars.\n\nIf someone tries to steal any of my cars, I will look forward to handling the issue permanently in a manner that will result in no charges pressed by the DA against me.

alarm is an electrical item which needs electricity to flow through to support it's functioning. 4-20mili ampere is a very little current which it's resistor can handel thus the design has been made like that

911 is free- but should only be used for emergencies

There are photoelectric and ionization types. See the ref.\nThe photodetector type shines a beam of light down a tube containing the air being sampled. A hole in the side of the tube passes any light that is scattered by smoke to the photodetector, whose amplified signal powers the alarm horn.\nIn the ionization type, a source of ionizing alpha radiation is beamed into an ionization chamber, where the nitrogen and oxygen molecules in the air sample become ionized and allow a small current to flow between the two plates that make up the chamber. When smoke is present, it disrupts the ionization process by attaching to and neutralizing the ions. The resulting reduction of current flow triggers the alarm.

You can buy a simple Radio Shack police/fire scanner. Essentially the same thing, but a much lower price.

You could use it in some sort of decoy method.  Post a sign that says "gas release on illegal entry" and wire it so that after the alarm system is tripped, CO2 canisters go off.  Then find some way to amplify the noise so that it sounds like the place just turned into a WWI battlefield with mustard gas everywhere.  Or if you rigged it up so it simulated a fire, with fog acting as smoke, and red and orange lights flickering.  But you might want to check into the legality of all of that. Why don't you just get a normal alarm system?  Or a big scary Doberman?

you guys are close. An alarm assignment is different in every Fire Department. What you get at each alarm depends on your Fire Department and how much apparatus they have. By calling for a higher alarm, you're getting more apparatus, and more manpower. It doesn't have to be 3 trucks for 3 Alarms. For example, if you've got a Engine and a Ladder Truck on scene and drop a 2nd alarm, you might get an additional Engine and a Chief. It all depends on what the ageny's SOP's are.

not a lot of people know this but smoke detectors are one of the biggest scams ever! I had one in my old house, one day it started beeping and beeping like their was a fire every so often. And then it stopped. Three months later a grease fire destroyed my kitchen and that good for nothing smoke alarm didn't even go off.

Factories... Use Group F (F1 and F2), single story, with an occupant load of 500 or less is not even required to have a fire alarm much less fire drills.  (ICC 907.2.4).  I simplified that a little bit.\n\nSo the real question is does this factory have all 600 employees working at the same time, or does it run shifts?  If they keep the occupant load under 500, then no, no fire alarm and no drills.  \n\nIf they do have a fire alarm system, then it is required to be tested at least once a year (NFPA 72).  However, there is nothing requiring a factory to actually have a drill, although they are required to conduct safety training so employees know what to do in the event of a fire. (OSHA)

I use Zone Alarm for a firewall. It has an option to lock and unlock internet acess.\n\nhttp://www.zonelabs.com/store/content/home.jsp
