I don't claim to be an expert on the Pyronix PIRs but i'm guessing something like this; the high setting will probably be the equivalent of pulse count 1, the low setting is probably equivalent to something like pulse count 3. The auto setting will probably switch between the two depending on...

They're definitely not a "point and go" camera. Take a look at some of the videos on YouTube on how to set it up, there's too much to go over on a forum really

Yeah, there's a jumper for sensitivity. Low, high and auto are the options, it may be worth trying the low option and seeing how it performs in your installation. The RX40QZ would be the one you want, unless you need the pet immunity function. I don't know of any specific reason why the Optex...

As per sparky, Optex are pretty much the most reliable PIR you can get. I have several RX40s at home, never had a problem with them. The KX15DT are fine, not sure on the DQ though. I would make sure they aren't set on Auto sensitivty for a start if you're not planning on changing them for...

Have you tried disabling zone 8 through the programming rather than linking the terminals together? It could be a poor solder connection on the PCB terminals. I've seen that happen a couple of times before but usually on older panels when service engineers "nip" up the terminals on maintenance...

I used to have a relatively easy life before Hikvision came along. Had a high school back end of last year, brand new install; modular intercom, ANPR cams and a 96 NVR all with firmware problems. It's decent when it works but when it doesn't...

I've seen some strange problems arrise on old machines that have been fine where a firmware update has sorted it but as above, you need to make sure you get the correct firmware for your machine. Newer units will reject incorrect firmware in my experience, but it is possible to brick older...

Isn't keypad 51 the internal keypad of the Galaxy? 5 isn't a valid branch number, would be 1-4 on a 520.

It's in the user guide, towards the back where the user code names and circuit text can be written in

Is the user number between 15-20? Can be used to send SMS/notifications when certain users unset the system but doesn't do anything under normal circumstances

Same thing. They're red LEDs, hence the recommendation for the red strobe lense if you wanted maximum brightness

They'll all be made from 3mm polycarbonate, it's in the standards for the manufacture of external sounders. 3mm plastic or 1.2mm steel

Is it a Premier Elite with the Smartcom communicator? If so, here's my experience: The zone that the detector is wired/programmed to needs to be programmed as "Moment Key", then enable the "Monitor when armed" attribute for the zone. You can assign the chime function to the zone if you want...

Unfortunately, this is commonplace on new build properties. The alarm typically gets thrown in by the site electrician, almost as an afterthought. I did a panel change on Friday on a 6 year old property that had just been sold for nearly £500K (expensive house for the area) It consisted of an...

It's a difficult thing to quantify really. Depends on many variables; ambient light levels, sounder supply voltage, angle of viewing, location of sounder on the building, colour of strobe lense/thickness of plastic etc In my experience, if you want really bright comfort LEDs, then a Novagard 2...

It sounds like the NVR is re-booting, it's possible that a surge may have damaged the PSU or some other component inside it. You will always get camera disconnect errors when the machine reboots, this is normal so there's probably nothing wrong with the cameras themselves.

There's your problem, those are gate safety photocells, designed to be very fast acting across a short distance and probably too sensitive for this application. They're also difficult to line up on anything other than a flat and perpendicular surface. I'd recommend swapping them for something...

Double knock is a feature of some control panels, the G2 doesn't have this option and I'm fairly sure that the Optima doesn't either (you'd have to check the manual). The problem with double knock in this situation is that someone would have to walk through the beam twice within a predetermined...

It's highly unlikely that your average domestic installation is going to exceed the capabilities of even CAT5e cabling to be honest, especially where CCTV is concerned. CAT6a is basically a higher performance version of CAT6 but again, the advantages aren't likely to be apparent in short cable...

The Flex panels will only support one Touchcentre, this can't be expanded in any way. You can have 1 Touchcentre per data line on the larger Dimension range of Galaxy panels but this would require you to change the panel to at least a Dimension 96.
