Shouldn't matter about DDNS on these.

These require good knowledge of IT and Premier Panels to setup. Sounds like you have the panel or ComWifi incorrectly programmed. Best I can offer is start again and follow the manual for the ComWifi word for word, reading several times before starting. External Dynamic or Fixed IP will not matter if setup correctly.

Err, well unless on engineer reset, no.

Have you reset the system? It's possible the battery charging circuit is faulty or has a blown fuse.

Eh? Anyway glad your sorted.

Assuming they're wired devices, it still sounds like a programming issue. It should work OTB, maybe if you can't find the attribute that's been changed start a fresh. I would also start to consider if the detectors are in the best location.

Something is programmed incorrectly. This shouldn't happen. Call a local installer?

You can't that would defeat the object of the alarm.

Time to start selling iD biscuits for £50 each then.

Do you not have a WP to test?

Yeah there's Lead Carbon, Sealed Gel but also LiFePo batteries are getting popular for mobility stuff and available in 7Ah I believe. But again is it worth the cost, really the system needs checking yearly anyway.

Lol, bit tricky to get the right voltage. You can get other types like gel and lithium but are they really worth the extra?

Removing the hold-off for a minute or so is enough to check the battery. If the sound dips or has a low output it's likely it's near to failure. They are Nicd so last longer than the lead acid type batteries in the panel. Depending on the box you can't disable the sounder triggering. It will have at least one fixing screw you can't have something like that in the elements only clip on.

Yes, if you know how to wire them correctly and you don't overload the panel, as I explained in post 2

Two live boxes could have been too much current and blown something. Most panels need additional PSU's or SCB mode for multiple sounders.

An additional power supply is not required and you do need the correct expander card. I would still use Low Current and/or SCB mode on the bell myself to reduce the current drawn by the sounder. The expander card comes with instructions, it requires an EOL resistor in the sounder but other than that it's simple. Yes, the GSM sends the same type of signals as PSTN, text message have zone information which is good. You have to set them up correctly with test signal enabled otherwise the SIM will expire. This is a one-way systems so not the most secure, would have to be a low risk site IMO.
