23. 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.

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

The above post is another example of "Paul's" suddenly improved English
grammar. It's the kind of thing Leuck claims he doesn't post. It is one of
several reasons I believe the Troll Formerly Known as Paul is not only not
Belgian but most likely an American.
Advanced trolls often use fake personalities as part of their ruse. It's
all a game to get the regulars to respond and, preferably, to irritate them.
TFKP is a classic example.

"Hiss" is a deliberate mispronunciation (in type, no less).

As usual you're unwilling to admit error. |
