Model number for panel is qi9201-1208-840, which is declared to be iq2+ at Qolsys.com. Is that true?
Yes, the QS9201-1208-840 is the IQ Panel 2+. Same model we sell in our bundles.
They don’t sell iq2 panels and it is a whole mess in Amazon where it is unclear if anything is really iq2+ or iq2.
I would discourage verifying product data on Amazon unless the listing is by the manufacturer. It is very difficult to trust the third party seller content.
Anyway it seems the only difference between iq2 and iq2+ is that the plus has a backwardly compatible card to accommodate legacy sensors. So it seems iq2 is has just PowerG. If that is so, it may be better to have, to make sure to avoid the legacy crappy, low security sensors.
No, it’s the other way around. Both the original IQ Panel 2 and the IQ Panel 2+ have 319.5 GE support (and S-Line, which is encrypted 319.5).
The IQ Panel 2+ also has support for Power G.
The regular IQ Panel 2 does not support Power G.
Some sensors are Interlogix 60-362n-10-319.5. which seem to transmit at 319.5 MHz. Does this mean they do not use z-wave since z-wave in N America transmits at 908.4-916 MHz?
None of the compatible security sensors transmit using Z-wave. Z-wave is used as a protocol for automation devices like lights and thermostats with the panel, not the security sensors. Power G, 319.5, and Z-wave are all mutually exclusive transmission methods.
Interlogix 60-362n-10-319.5 are standard 319.5 mhz sensors and are not encrypted.
In fact my other sensors are classified as S-Line at Qolsys.com. Do S-Line sensors adhere to z-wave s0 protocol? Or maybe they’re not at all using z-wave, if so what are they using?
S-Line sensors use an encrypted form of 319.5 mhz transmissions and are a good option in terms of RF security.
Qolsys doesn’t have any PowerG sensors at their website even though their iq2+ panel advertises it has PowerG. Is PowerG the same as z-wave s2?
Correct, Power G sensors aren’t made by Qolsys, they are actually made by DSC.
Power G sensors are at the top of the industry however in terms of wireless security, so Qolsys made them compatible with their system.
Power G is not the same as Z-wave. They are two separate communication protocols.
Z-wave is a mesh network where individual devices have a shorter range, but AC powered ones repeat signals, which makes it great for automation device networks like light switches and thermostats. It is not as reliable for security sensors, since battery operated Z-wave devices do not repeat signals. It is because of this and other factors that no Z-wave security sensors are yet compatible with any Alarm.com system.
Power G on the other hand has comparatively extreme range and the most RF security benefits as mentioned in the prior post.
