I did read your later post correctly. I was explaining the reasoning behind my initial post. Maybe re-read what I have posted as clearly the point of calculating standby time has gone unnoticed. There is no "spec" for the panel, merely some information copied from an old manual that is irrelevant to the point I was making above. Either way running the second bell as SCB would be the correct choice IMO. You would have to measure the temperature of the cab with it shut to be certain. Can't imagine anything much above 30C even with poor air flow. Probably not. Probably yes. I am You shouldn't be loading it anywhere near maximum rating, as above. I have already said, significant extra current will not be drawn from the bell trig for the extra sounder. Plenty of experience with them, from the jokes above you can see most would have it heading for the skip. Maybe, I wouldn't try. There pretty bombproof from experience. An additional PSU like explained Eh? How does that change the system output current. You can draw approx 1A from the panel, that would be the total of all the powered devices on the system. Anytime tl;dr - I would suggest you stick the bell up in SCB, make sure you connect your tampers between the bells correctly and move on to the next job.

Yes, it would be 8 for pre-EN. However, I was making the point that you can't just load a panel up to the maximum the PSU will take or the maximum from the manual then expect everything to be fine. There could be a 1.2Ah battery in there for all we know... The bell trig shouldn't have much extra load so you shouldn't overload the TRIG output. I wouldn't have two SAB's on any panel without additional PSU TBH.

You haven't thought about battery standby time for whatever battery you have. Would it last 12 hours with one activation on your standby battery?

Any reason? If it's reliable and flexible enough to use from domestic to 640 zones, it seems an obvious contender.

You seem surprised?

Always liked Giugiaro designed vehicles especially the Italian models all very boxy shaped but IMO had there charm. There is a bubble at the moment for that era but if they last long enough to go beyond classic and become a rare classic in mint condition they will keep there value.

Give the keypad a clean up, new battery, programming manual. You'll have all the mat switches and racals back on in no time...

The Evo2 was after Group B era, would have to be Martini White over Rosso Red.

Nah, good winning well designed car but never liked the look of them. 6R4 and 037 for the higher class, 205T16 and R5T in the lower class. They all have crazy aero but don't spoil the look of the vehicle IMO.

Feel free to ask for advise re any quotes you get.

I always liked the 6R4 my favourite of the Group B era, especially in the Computer Vision colours. Not only is that thing a 5 door it's a Rover not an MG, waste of a bodykit IMO.

Not in this weather...

Sorry we can't share manuals here. I imagine it will be 5 wires, the other terminals may be for extra features. Either way if 8 core, wire them all up and you can do whatever testing at the controls without being up and down the ladders.

CQR Alto Speaker. https://www.securitywarehouse.co.uk/catalog/cqr-16-ohm-extension-speaker-p-4997.html

Would use an extension speaker wired to the spk terminals myself.

Agreed, it makes sense for a few reasons, so I realised at the time. a) You don't need to reset if you have a site with intermittent issues (as at G3 tamper should be eng reset) b) It displays on the keypad and log as a separate event to a tamper, increasing your information for diagnosis. c) Mask on most controls is above 10K, having this huge shunt resistance increases the threshold of any fluctuations from the reed.

Tamper loop is part of the interference reed circuit on most of the ones I have fitted. I remember a thread a good while back, had issues with both CQR and Elmdene on one site, seemed to be environmental. At least with the Elmdene there technical explained which colours did what so I could make interference reed trigger masked instead of tamper, you have no option with CQR.

Really? I was wondering why it wasn't like that in the first place....

Beams?

You'd hope so.

Tags going missing or lost in the mud, not enough staff to man the clocking in and out, scouts passing back or swapping tags. I can foresee plenty to go wrong.

MBR only supports addressing upto 32 bits which is the limitation on 2TB I don't recall seeing a PATA drive larger than 750GB.

Second that, once caught glimpse of a baby being preped for embalming, while doing a walk test.

Most of these little domestic panels are non-conforming or G1 anyway. It's just common sense not to display the system state outside the protected area, never mind regs. The panel is too basic to program anything useful from the outputs for indicating arm ok.

I think access control on a scout camp is asking for headaches and trouble. I would look at something more suited to controlling large mobs of people like festival tags for example.
