PCB clearly shows 'Texecom 1996' so looks like a Viritas R8 as already stated. Looking at the last 4 terminals on the PCB. These were for the RKP. I remember you had to be very careful wiring up at this end of the PCB as the circuitboard wasn't supported and often, a year or so later, any cracking of the board would exaggerate and cause RKP problems that were a pain to trace. Also on the example above, theres something else wired into the RKP power as well as the RKP. Not something that was tolerated before texecom created their smart datalines that resisted dirty data.

LOL. My ex boss got a deal on a dozen mini piezo's. The small white square ones with the grill on the top. The whole lot played 'Yellow Rose Of Texas'. For 5 years I was itching to get on the installation that he bought them for but it never did turn up.

The microwave element of a dualtec is ajustable in most if not all detectors i've seen but I'm sure their minimum range is still some 8 metres although this will be less if the detectors mounting height is reduced. I would have thought still too long for your motorhome. The microwave element also has a wide spread that would reach and break through the walls of the motorhome within a couple of meters. To have a dualtec fitted would mean a hell of a lot of adjusting including screening the sides of the lenses. By the time you are finished, it would be close to useless. A fibreglass body would not stop the microwave element detecting outside the physical perimiter of your motorhome. Quads could be viable but you'd be defeating the object of installing one adjusting the pulse count to 3. Crow do a great quad, the SRP700 which if requested, can be fitted with a black lens which helps in those direct sunlight situations. The Crow Genius is another quad that is great in harsh environments. I've fitted one in one of those BandQ steel kit sheds with no problems. If no expense spared, the Crow D&D works fine in swimming pool areas and outside and works from 9vdc too. Just out of interest. How is your alarm powered? Tony
