Only problem with these devices is , that you need a contract SIM 2g , most of them don't work with three or similar Sims they use
Cheapest contract sin these what £6-7 per month? So your better off spending a bit more on better GSM unit like from advent controls and you can find the odd sin only supplier for £4/5 per month
Earth to DD?
The 9651 doesn't have a plug in dialler, pins are for pins coms as jw said
The ion range used the plugin dialler
As jw get a standalone dialler and use bell trigger or the pins outputs for triggers is possible
Similar problem with the hkc I assume you mean at night efault comes up loss of Wi-Fi, common with hkc Wi-Fi cards as well, you can turn off the audible notification that you have lost Comms on the panel itself you would still get the notification on the app that you have lost comms with the panel when you're out not sure what you mean DD about using home plugs he would have to change the Wi-Fi card and use a network card of sorts
Sounds about right
Google Amazon etc , will make to many differing products due to sales targets no one will ever be happy , except short term
By then tasers will be legal !
Wiring can be common
Addressing is give a number or letter like a house having a door number or name, so the control panel knows who is who like a postman needs to know what address to goto
Not sure about the comes device tho lol I don't use the panel but if you give up I will have it
