Update as promised following installation of Scantronic 9651: Installation was fine and programming was very easy. All tested and working OK. I still need to check the current loading as above. A couple of points to help others: 1) The bell box tamper gave me some trouble (Risco XS dual piezo). Problem was the extended arm on the tamper switch needed bending out so that the lid actually closed the switch. Tamper wiring not intuitive - believe what the bell box instructions say, i.e TR from panel goes to 0V on the bell box. If you wire TR to TAMPR, the bell box won't ring if the lid is taken off. I rang Risco and they confirmed this. 2) The AC fail lamp does not flash immediately on loss of mains. It must be delayed by approx 5 mins before an event is logged and LED flashes on the keypad. I initially thought I had a faulty keypad. 3) Programming function 28 has a table in the 2007 manual to select what is shown on the LCD display and how the alerts/mains fail lamps operate. I wanted the time and date AND the mains lamp active all the time when unset. Whether you select option 0 or 1 the behaviour doesn't seem to exactly match the table. I've experimented with it and you can have the mains lamp on all the time but not with time and date. Selecting 'timed' and you can have the mains lamp for 30 secs but not time and date, just the last action, unset B, for example. Strange. Not the end of the world but it would be nice if the functionality matched the book. Obviously if anyone has any experience or comment, please let me know. In general, the 9651 is a well-made panel and simple to program and use. The best panel I've installed. Recommended.

I haven't had any responses yet from previous post but have had the following further thoughts on the questions I posed: 1) The keypad, a twin piezo Risco bellbox, 5 Bosch dual tech PIRs and a quad piezo sound bomb, supported by a 7Ah battery seems like a typical system, doesn't it? 2) I think all I can do is omit the front door and program the hall PIR to be final exit on part set. 3) Sound bomb between OP3 and 12V with OP3 programmed to behave in the same was as the bell activate, i.e OP3 goes to -ve on activation. I shall be going ahead with the install from Friday with the above and will update with experiences/problems. In the mean time if anyone has any advice on the above it would be appreciated, particularly with regard to power loading. Cheers.

It all arrived last Friday and have had a good read of the installation manual, which is extensive and much better than I've seen with some of the other systems I've installed. Programming looks straight forward too. As always there are a few questions in my mind, perhaps somebody could offer some advice as the scantronic/cooper support is only available to registered prof installers and you need a PIN. 1) Assuming the max battery charge current of 250mA, the remaining load on my system is 490mA+95mA for the dual piezo bell box with strobe, 110mA for 5 dual tech PIRs, 125mA for the internal sound bomb and 70mA for the keypad with backlight on. Adding all this up it exceeds the figure of 750mA so the total loading of the system is in excess of the 1.0A that the user manual specifies as a maximum. These are worst-case figures but should I be worried that when the system goes into alarm it will be over-loaded? Another point of concern is that the 12V aux is rated at 500mA and this supplies the PIRs and the sounder, the sounder being 585mA on its own. I suspect that the PSU is capable of meeting this load but would be good to have confimation. 2) On full set the front door is the final exit, the PIR in the hall is designated an entry route. For part set I can programme the PIR to be the final exit so that when coming down stairs in the morning this will act as a reminder to unset the system. Since I work shifts I could enter via the door with the system part set. If I change the behaviour of the door zone on part-set to be a final exit, will this still work? I would have two final exits so the timer would start when the door is opened, would the PIR in the hall go into alarm as this won't be set as an entry route on the part set? 3) If using fully supervised loops, what should you do with the global anti-tamper? Should it be linked out? 4) I am planning to connect the sound bomb between OP3 and 12V. OP3 is an open-collector pull down so when it is active it will go to 0V, hence 12V across the sound bomb and the thing sounds. Is this a good idea? Any help gratefully recieved, if anyone wants any further info let me know. (sorry for the dump of text but short of time!)

Thanks very much for all the advice. Now that contracts have been exchanged on our house move I will be placing an order for a 9651 which looks like it will do everything we were after. Cheers.

Hello, Some years ago I installed a couple of Tate alarm systems. These were fairly simplistic but allowed the external siren (and any internal sound bomb) to be disabled on night set. Since then I've moved over to the Pyronix Sterling 10 as I wanted a full text log. The Sterling is OK but had no means to disable the sirens on part set and the log has no date/time stamp. I'm moving house again and will be installing a new alarm. I want a system with a date and time log and the ability to turn off any internal siren and just have the normal speaker tone on activation. I've always felt that deafening and disorientating an intruder with a sound bomb is probably more effective than the bell box, but at night, with us all in the house, this isn't so desirable and the speaker is more than loud enough to wake us and scare off an intruder. I was considering the Scantronic 9651. This definitely has the log function but not so sure if you can select which sounders you want on part set. Can anyone clarify, or suggest another half-decent system that would meet my requirements. Its not essential that the external sounders can be switched off, but in my (limited) experience the sound bomb is connected in parallel with the external sounder. Any help gratefully received.
