My system? I designed, built and installed it myself and it qualifies as a full class A, UL rating. It took nearly seven months to complete.
In addition to knowing that it always functions with zero false alarms, the city has awarded me with my own alarm permit. This means I am self monitored, and therefore do not pay a monthly fee or service contract. I dislike paying someone who eventually telephones the police after trying to reach me for ten mins. I provided a direct line to the nearest police sub station. The device calls and identifies itself and the problem as to fire or force entry, gives the address and Mapsco codes, my contact information and an emergency number for the police to locate me. If the land line fails the break directs the box to use the static cell phone that is part of our "family plan, " so is essentially at no charge.
There are two other systems in addition to this one. One is a sensor in the garage, simply rings chimes in the house if anyone walks within 20 feet of the automobiles. The last is infrared sensors covering the back yard. These were manufactured by Pulnex in Japan, and can bet set to not see birds or squirrels, but detects humans of all sizes.
Both systems have their own Electro Voice horn drivers in steel boxes (with tamper switches) with a siren module driving them. Output is 117 Db at one meter for each. I will wager too, that this is the only system with exclusively Wonder Solder connections. I realize this does not contribute to sound in this case, but there is much less chance of corrosion, compared to the hurried crimp jobs that most installers do.
A raccoon fell from a tree and set the system off one night when we were all out, and a neighbor, four houses down and across the street left two messages on my service, complaining about the noise. Even though her house was brick, and she was that far away, the noise interrupted her TV viewing. Guess it must be pretty loud.
