Hi everyone:
Am a new subscriber to the forum - I've been reading posts for awhile, and there are lots of knowledgeable folks on this board ... glad to be a part of it.
I'm hoping I could ask a few questions about our Vista 20 alarm/fire control system from Ademco.
We have these Vista 20 systems installed on our campus (a church, a school, a house and an office). The building I have questions about is the school.
Let me start off by saying that I know for sure what we have is not 100% up to code. We are inspected every year by the fire marshal, and he's happy with what we have, so I guess I'm happy, too.

We have a renovation coming down the pike in the next 5-7 years, so I'm sure this will all be replaced with new equipment when the time comes. We're going to try to keep this "limping along" for the meantime.
We were having a new roof put on the school, and the roofing company wasn't careful in covering the roof while they were working on it, and yep ... you guessed it ... water all over the second floor of our school.
Water came pouring through a large section of ceiling, passing completely through two of our smoke detectors that were mounted on the ceiling. Now, the control pads are all showing FIRE TROUBLE 01. Will replacing these units work, or is there a fault in the wiring, and we'll have to do all new wiring for them as well?
The second question I have is about conducting fire drills in the school. We have a Simplex 2001 fire control panel, with pull boxes throughout the school. The Simplex box is somehow hooked into the Ademco box. We discovered not too long ago that when a detector detects smoke and sounds the alarm, both the Ademco sirens and the Simplex sirens sound at the same time. We have been conducting fire drills for the last several years using only the Simplex system, but we now want to conduct drills EXACTLY as they would happen in a real emergency and sound box sets of sirens.
The suggestion was made to silence the Ademco sirens and only sound the Simplex sirens, but the problem with that setup is that there is an Ademco siren mounted on the outside of the building, and it serves as the only audible alert to people in the other building that something is wrong in the school. So ... we really don't want to turn them off.
We also discovered that when a pull station is activated, only the Simplex sirens sound.
My questions:
1. Is there a way to program the Ademco system that when a pull box is activated via the Simplex system, that both sets of sirens would sound?
2. If that's not possible, is there a way to program a button on the control pad to sound the fire sirens (like a fire panic), and then we would also manually sound the Simplex sirens, as done before?
I hope that this isn't too too confusing, and that I explained it well enough. If you need clarification or any other info. that I can provide, feel free to let me know.
I know this is LLLLLLLLLLONG! Thanks much for reading, and for your thoughts and suggestions.
Take care,
Michael/AdemcoWisc
