Re: Ademco 50P - Unable To Disarm

["Crash Gordon" <webmaster@xxxxxxxxxxxxxxxxxxxxx>]

You're gonna power your smokes from the panel's power, not the separate
power supply - or however the panel's instructions say to power them (I
don't use polling detectors, so I can't tell ya for sure)

IIRC= If I remember Correctly

| Whew!  My thanks to everyone for your responses.  Although I am
| suddenly hesitant in my expectation of some pretty strong,
| ehh...ribbing, I will try here to respond to the messages since my last
| posting.
|
| The direction of the discussion here had already led me to the decision
| to rework my wiring in the panel closet as Ranger advises.  Combined
| with Crash's specific suggestions concerning power supplies and my
| assumption that such supplies have the terminals for 4-wire devices
| such as the smokes, I think I have a reasonable idea as to how to
| begin.
|
| I had read the manual several times which originally led me to the loop
| extender in order to maintain independent zones for each item since the
| Vista 50P could provide only eight zones in this design.  My life
| experience that manuals frequently leave out important information
| either as too basic or irrelevant appears, however, to have led me down
| a garden path in re the 4297.  This is where the folks here can groan
| or laugh, cry or....
|
| The 4-wire devices, including smokes, wired to the 4208U expansion
| modules have the data pair connected to the individual zone data
| terminals.  But then, the power pair from ALL such devices are together
| wired to the expansion module's power terminals.  This is to say that
| the terminals which supply power to the expansion module are "tapped"
| (if I can say it this way) by the smokes et cetera. So, yes, I have
| connected the 4-wire smokes to the polling loop but only (?) the data
| pair.
|
| I know it is a joke, but no one here has sold me anything nor did I
| have contact with anyone in this group prior to completion (ahem) of my
| installation.
|
| Yes, I got it that contact and relay ratings are not the draw and that
| waterflow, heats, and contacts do not draw at all.
|
| My google on Altronics led me to an Australian computer power supply
| company.  I will seek out the Brooklyn concern.  IIRC?
|
| Although I understand what is meant when I am corrected, a google on
| the term "DC transformer" turns up some interesting though irrelevant
| information.
|
| Thanks again to all.
