Just wondering if anyone has any comments on Scantronic 460
dual tech (PIR+MW) movement detector?

The [wired] dualtechs I've tested, been happy with, and used
in the past have all gone obsolete now, so I'm looking for a
new one to use. I've picked up one of these to try out, being
reasonably priced and available, but would be interested in
any other experiences of this or other current products.

Re: Dualtechs
Hi
Nice unit but with all devices it depends on location Don't use a lot of
Cooper Menvier gear as it is somewhat expensive for domestic market and
Honeywell (galaxy) fill the industrial gap well enough.I use Guardtec
(risco) dualtec's in most cases for domestic and Texacom for small
industrial app's but again most of these devices now have near enough the
same longevity and they all supply various specification units for almost
any installation.

I published a review of the units I tested.

Just to update with the experiences of running these for 10 years...

Lynlock Focus Dual-tech:
Two units lasted about 5 years each before becoming unreliable and
generating tamper alarms (which is its method of reporting internal
fault, or masking). I had initially ripped most of these out anyway,
due to generating spurious masking alarms with no way to disable
the anti-masking feature, but there was one place in which they
seemed to work well, and lasted for 5 years each time.

Pyronix Equinox 10 (dual-tech):
All still working perfectly, but did have to increase the sensitivity
in one of them after about 5 years to maintain coverage. Fortunately,
all are set near the lower end of their sensitivity anyway.

Guardall Astra Micra S-8 (dual-tech):
All still working perfectly, without any need for adjustment.

Pyronix Octopus (PIR-only, ceiling 360 sensor)
Not originally reviewed, but I also used a couple of different
models of these. After about 6 years, some spurious alarms from
several of them, fixed by replacements with new units.
