26. NEWBEES, if possible avoid wireless alarm systems

They are not reliable and are dead on warning when a transmitter operates in a condition who muzzle the wireless alarm system.

This is easily done with Radio Transmitters operating:

- ON the wireless frequency

- Saturating the receiver

- Intermodulation

- Harmonics

- Falling in the receiver bandpass

- On the IF frequency

- and more... This is what i call basically Radio Frequency Interferences (RFI) but in fact it covers, like you can notice above a lot more.

In essence the problems is the fact that by no way two (or more) systems can use simultaneously the same frequency, its called collisions, interferences and more like you see above.

The WORST is that the OWNER DON'T KNOW THAT HISS alarm system is no longer operational, no message (20 years records hold by so called experienced professionals: no RFI alarm).

Use a wired systems and use WIRELESS only when impossible to wire, but BE AWARE that YOUR SAFETY IS HAZARDOUS (my system was dead during more than one year before i found out by accident and measuring the wireless receiver output signal content). Muzzling can occurs permanently or occasionally, mine was permanent.

Note: So called low level mechanically (who claim them self professional) try to let you believe that my system was dumb and/or badly installed and they don't realize that it is an external influences that can't be avoided whatever wireless alarm system you have. Its a pure radio communication problem know by telecommunication specialists. There is a way around for $$$ investments but that is out of reach of a wireless alarm system.

Paul NOTE: My system is replaced with a wired one, do the same.

Craig...you're trying to reason with an incorrigible moron troll (he wears underwear made of tin-foil)...don't bother he'll make you crazy too.

Just an FYI, most wireless systems, if they are to meet UL requirements for resi or commercial burg (and fire too for that matter), are REQUIRED to send a supervisory report at least every hour which includes bits that tell the panel the batteries are low. UL requires that this signal is sent consistently every hour thereafter, and the battery must last for two weeks after the initial low battery signal.

As for interference, most panels if they are worth their salt include some sort of option which provides a time window after which, if the above-mentioned supervision signals are not received from EVERY sensor, the panel will notify the user and/or the central station. Thus, it looks like somehow your system may have been sending the signals to the central station but not alerting you.

Out of curiosity, which system was giving you this trouble?

The panel will send a jam when any of the transmitters are jammed (your term: muzzled) or if any of the transmitter batteries are low, or if any of the transmitters do not check in within their specified time frame which on some systems can be set to specified time frame, but most check in every hour.

Patently incorrect. See above response.

We have all read your misunderstandings of how wireless alarm systems work. I suggest you read and try to understand our responses rather than rant on about something you just don't understand.

In addition: IF you had done this much research BEFORE you bought the piece of crap alarm system you had a problem with you would have (MAYBE) bought a reliable system instead.

I'm not talking about the panel but the sensors who are blown out when Radio Frequency Interference (RFI) occur.

I like your statement "option" and what about the others, how do they react when RFI occur and muzzle incoming sensor signals? By the way having that marvelous option that give a warning after a long period is of no use or not efficient for intruders. The long period is required to avoid false alarms and it give only a warning that the system is bingo. It don't solve the inability of the system to give any kind of alarm because the sensor signals are no longer valid due to that RFI muzzling problem anyway.

Its not a mater of type of the system, its a mater of radio data communication who is unreliable/unusable when an other transmitter use and block the sensor alarm convey frequency, the problem is known by radio tech's as RFI. ALL wireless alarm systems go bingo when RFI occur. It seems that you didn't read my other posts about it.

I'm discussing with "Craig B" not with you who has proven already enough that you are a stupid "low level electrician" who don't know how radio com work.

But if by any chance I'm wrong and YOU know better, please explain, its to the benefit of all readers (so called pro's included).

Ah...actually I have 2 FCC licenses and about 41 years experience in radio, 25+ years experience in the alarm industry, and a few degrees that I won't bother to mention. Whadda you got? Nuttin right? Yeah that's what a thought...just a bottle of Zoloft...or was it Lithium?

Aren't you embarassed by your ignorance? Don't you know how utterly stupid you come off?

Dunno what the f*ck you're talking about. If I sold cars for a living would I have to have designed it?

No, I don't design, manufacture, sell, install, and service alarms...doesn't mean I don't have the knowledge to do so, but I don't design/engineer the components. Do you?

Poor guy? Heeheheeee....yah I'm poor...you know what RMR is?

Take 2 more little yellow pills and send me 5 bucks in the morning you moron.

Experience in alarm industry, he? Hammer, cleaning cloth and finger in the wind measurement tool or did do you participate on engineering & design of alarm system?

Poor guy,

Now i understand why you have such an elementary "ball" pen with you behind it. Your 40 years experience without upgrade is now vinager like an old bottle wine who passed over.

Yes, i design from scratch more complex equipments than alarm systems.

I design from scratch with my personal engineered concept and fully certified equipments containing uC computer with appropriate software, pneumatic and pressure transducer, electronic,... in short stand alone devices for paramedical use!

Wireless alarm systems are not very sophisticated low knowledge for installation and maintenance only a hammer or cleaning cloth.... Programming, let me smile and call it rather setups.
