Re: Adding Sirene /speaker and Strobe to DSC PC3000

> 1. What is the difference between a Siren and a Speaker?
A siren to me means a self contined unit that only needs straight DC
volatage to activate. It can be mechanical (like a bell) or have integrated
electronics (siren driver).
A speaker is just that, a speaker like on your home stereo or car radio. It
needs a separate siren driver and accepts that AC type input.
>> 3. Would like to add one more. Siren or Speaker???.
This is easy to do but might not be practical. There is a limit to the
output of the alarm system and not knowing what is on there already you
might overload the system. A PC3000 is fairly old stuff already.
You have enough knowledge to cause yourself some problems. Until you know
how to measure a load on a circuit and the difference in series, parallel
and series-parallel circuits (or are willing to learn) stick with what you
have.

Typically stobes hog less power and would be safer to install but not
knowing what is on there already means there is still some risk of
overloading.

That might mean the system would keep the signal going until it was
disarmed; maybe be okay for a strobe only connection. If you use that for a
siren trip as well and if you left on vacation and returned days later (and
had an alarm in the interim) there would be angry neighbors and a police
fine for excessive noise I suspect.
