wont cause an issue, most that fit still forget to remove the jumper/cut resistor in panel when using two data lines.
Honeywell never ship them with keypads or RIOs which is a shame.
We do fit them but use standard alarm cable for anything under 100M now
Is there really one?
Most of it comes down to lack of knowledge or understanding from the installer.
Some hate Galaxy, some hate Premier etc, its mostly because they have been sent to take over one and try and understand it in an hour.
