I know! Doesn't it seem a little silly to have a "BACKUP" device
that's never even tested until some unknow time in the future,( like
maybe a couple of years) when the land line goes down?
If you just went by the installation instructions and the default
settings, that's exactly what would happen. The manual doesn't tell
you a damn thing about alternatives and consequenses.
1. Line cut
2. GSM3055 sends line cut signal thru wireless.
3. GSM3055 cuts over all communication path to wireless.
4. Main control in alarm.
5. GSM3055 senses panel DTMF dialing, then provide a handshake signal.
6. GSM3055 captures CID transmission from panel and send them out thru
wireless.
6. Network conversion
7. GSM3055 sends kiss off to control panel.
8. Land line restore.
9. GSM3055 cuts signal path back to landline.
Meaning, as far as the control panel is concern, the phone line was never
dropped and the GSM3055 acts like a switch between landline and >wireless
I think that's kind of dumb, don't ya think? Why wouldn't you want to
know that the telephone line went down? I know there are ways to
detect it, but the manual doesn't give you any details or suggestions
to do it.
You just KNOW that someone out there is going to intall these things,
out of the box, thinking that they've actually got a backup device and
all they've got is a dumb, re-transmission device, with no
notification of failure or verification that the system is acutally
working.
One thing you have to watch out for is, when subscriber cancels phone
service, the line voltage does not drop for a couple of months if not longer
so the GSM3055 will never switch comm path to wireless network. So it is
very important to trip one of the onboard inputs with the main control panel
bell output for backup signal transmission. The 4 onboard zones send >unique CID codes so you won't mix them up with the regular CID signal >from the digital dialer.
No they aren't unique. See my other post with some of the codes the
unit sends.
