I am working on fixing a 4-wire smoke system that a previously installer screwed up when he installed a new panel at my parent's home. I have a Vista 20P panel, 449CST smokes and a 405-03 reversing relay (the last smoke also has an EOLR built in). The previous installer did not hook up the reversing relay or attach the smokes to a switched power source.
I am trying to figure out how to wire up all of these devices properly.
I originally, purchased a separate power source to power the smoke detectors because the combination of the smoke loop with the other devices will exceed the panel's aux power circuit when in alarm. After looking at the schematic for the reversing relay, however, on alarm the reversing relay switches the power source to pull power from the bell output which is more than enough to power the siren and the smoke detectors. So I assume I no longer need the supplemental power source.
Now my question is 1) will the use of the reversing relay work to disconnect power to the smoke detectors and reset them once the alarm is silenced and the relay switches back to its normal configuration? 2) is there something in this reversing relay that is able to only activate the other smokes when one is in alarm or will all of the smoke activate every time there is an alarm event regardless of whether it is fire or burglary? I thought I read somewhere that this was the case, but cannot find anything in the literature.
Thanks in advance for the help.
