What's wrong with the panel if it works? Stick a new NiCd pack in the old bell job done, if the bell is operational. As for fitting the new, you seem to have worked it out, red and white are connected to the same place so the same thing. Engineer hold off wasn't really around when the 700L was made, so do with it what you want. If your not sure, try wiring it up on a short wire adj panel before messing about up a ladder all day.

Point being a speech dialler is designed to be a speech dialler where as the COM2400 is designed to be a digicom/modem. You require a speech dialler I assume, and while a combination of the correct panel, digi and speech module will do the job it's still not a stand alone speech dialler. The pro's and con's of each method are laid out, it's time to decide which direction is best for your application.

Certainly sounds like wireless sensor battery saving to me, where they sleep after being triggered.

They are SMA connectors. I have used SMA to F type connectors in the past to utilise existing loft bound coaxial. Obviously you need to end up with male/female to make an extension lead.

Speech Module 2 is only compatible with the later Elite "Hardware" and COM2400 combination. If you don't have this you will not be able to acknowledge calls as there is no DTMF chip on the main board. Only two telephone numbers are available per ARC setup, to have six numbers you would have to assign all ARC's to the same device. I have never tried this configuration with the Speech module but you will end up with three primary numbers and three secondary which isn't ideal. A speech dialler in contrast would have 8 numbers that can have repeat options set individually and in order.

Exactly. I don't think free apps will disappear, you will just loose functionality. I prefer to stick to products that allow me to control all functionality. You can't ever rely on a cloud service that in it's T&C's has permission to move it's goal posts whenever it feels.

T-Bar aerials normally have a indicator for ground, which should point down to the ground. You can try different aerials but you have to be careful you don't create more issues. For example, you could use a longer aerial (or extension) to get to an area of better coverage, however, the longer cable could decrease the benefits from that.

Increasing the ATS Fault delay would only mask an issue. The aerial could do with mounting correctly, making sure it's the right way round. The unit should be powered down from the COM port if you remove the SIM for whatever reason, which I believe you did? The third light flashing indicates you have marginal signal so I would assume it's just a case of poor signal. Try resiting the aerial or switching networks until your signal is good, solid light.

But if the lines cut you'd get neither message anyway. Trying to send a TAP message and using a speech dialler on the same line and the same time is asking for hassle. Well TAP is hassle full stop anyway TBH.

Is that for fitting the PIR's or removing the pets?

Sounds like the landlord needs to get someone out to either service it or decommission it. If your a tenant it's not your call on having it removed etc.

I fail to see the point of fitting a pointless piece of plastic you have to remove on each service anyway. Wouldn't bother with the screw caps either, I have seen them rounded off and jammed in before now, although this would be on the Veritas case not the Prem. Plastic caps and similar covers are just asking for screwdriver rash from numpty engineers and offer minimal aesthetics for there existence IMO.

GJD Multispeech should do what you require. Drives a 8 Ohm speaker from NO or triggered inputs. No SD card it's stored on the board.

Not any more...

Wish I'd thought of that, I had to make do with sticking flat bits of ABS together with DCM.

Exactly, just like I said in my first post. It's good to have knowledge of the basics, so start small but also consider tech moves on. Back when Logic 4's where designed a office desktop computer had less power than a SBC's you can buy now. A RPi3 is about £30, wouldn't like to guess what a P5 Pentium system or the like would have cost. The other benefit is if you get bored of the project you can easily repurpose the SBC for the next project. If you are really interested in making up some circuits maybe try some basic timer circuits to start, 555 timers are normally good to cut your teeth on. They are very easy to build a working project and if wired in the different modes, give good understanding of RC networks, transistors and logic level. This is assuming you are starting from minimal electronics knowledge of course.

Normally the bin... However, if you would like to locate them somewhere other than your local recycling centre; they fit in the screw holes after you put the lid on.

RonJ has some good schematics on his site I have used some of them before. From what you say in your posts you seem interested in the electronics but never build much before? If this is the case take a look at Ron's smaller and simpler transistor circuits first, before you build up to the modular one posted. The IC's are all pretty standard CMOS 4xxx Series, cheap and easy to pick up. I wouldn't start reverse engineering a Logic 4 as your first project tho.

It's all relative on what your trying to make and for what application. I have made alarm circuits on stripboard before, they where designed specifically for minimal standby current. In essence it's basic logic, you have inputs and outputs, the more you want to do with it, the more processing you need.

While old schematics maybe interesting it's unlikely you will find any available, they are normally kept in house. Very few engineers would repair down to component level and manufacturers would prefer to keep there designs to themselves. Unless you specifically want to work with ATMEL or PIC's, you could make something with basic components or use a relatively low cost SBC to interface with sensors on GPIO.

Providing the lamp has a day night sensor, yeah.

I would assume the tamper on the outside sounder is faulty.

I assume it needs a service and a new battery, that's if no ones looked at it in 20 years.

Excel isn't a popular panel, may have spoke to someone unfamiliar with them? I have no idea what your asking here. Are you trying to repair or get quotes for your own system here?

From memory you don't set zones per suite on an Excel. The zones are only enabled or disabled using the full and part suite options. The type changes are in another menu and are global for part, so you have it's full state and part suite(s) state that's it.
