Re: Hook in AC Fire Alarms to Security System

["Crash Gordon" <webmaster@xxxxxxxxxxxxxxxxxxxxx>]

I believe for line carrier to work (send a signal) there actually have to be
AC sine wave present, which means it won't work if there's no AC.

I don't know about others but when I do residential fire, not only do I run
the smokes in firewire, but also; power, siren, keypad and fone...not that
the wire is fire proof but at  least it may last a little longer.

| I'm not sure I understand this comment. How would I be trusting my
| family's lives on line carrier line technology?
|
| Today (already installed in the house before I purchased it) I have an
| existing AC Fire Alarm system with battery backup. In the event of a
| power failure and a fire, the alarm will go off and notify everyone in
| the house to evacuate.
|
| So my question is - how would this functionality any different than a
| system hooked to the panel if say the alarm's circuit board fails or
| the phone line melts? The fire alarms should operate and go off in both
| cases will in the event of detecting smoke but without any monitoring
| notification. Shouldn't it be exactly the same functionally?
|
| Right now the system I have for fire is standalone and obviously not
| monitored, but how is it any different functionality-wise if I hooked
| into the panel over carrier line technology than not having it hooked
| in at all? It would still be the same system I have today. So I'm not
| sure how I would be trusting my family's life on this?
|
| My only thought was to possibly add in remote monitoring to my existing
| system to add additional protection while I'm NOT home. And yes, I
| understand if the power fails the system connectivity to the panel
| would fail rendering the system completely useless (i.e. no remote
| monitoring would be possible.) But once again, how is this any
| different than what I have today? No difference and still no remote
| monitoring.
|
| Actually, I really thank everyone for taking the time to provide their
| suggestions and comments on the subject. I gained a lot of valuable
| information on this topic and I will probably just install a few
| strategically placed wireless fire alarms throughout the house (as this
| seems to be the more preferred approach.)
|
| Honestly, I didn't mean to do any "trolling" on the subject, but it
| definitely seems like very debated discussion topic from what I can
| tell now! Oh yeah, one final thing.. for those of you who are wondering
| - NO, I'm not trying to install a faulty monitoring system to off my
| family in a house fire so I can collect on the insurance money!! <grin>
|
| Anyhow, many thanks!
