It depends upon how the Napco panel and siren driver were programed (if it'=

a burglary and will warble intermittantly for a fire.=20

Now days, I use a voice siren driver that verbally announces either a burgl=
ary or fire. You are actually a good example of why. From your post, it sou=
nds as if two possibilities exist in your installation. ... 1, Your install=
er programmed your system with a driver with only one output or ... 2.... y=
ou have not tested the system to know the different sounds your system make=
s to indicate a burglary and a fire alert.=20

In such a situation, if you were to be awakened in the middle of the night =
with the siren going off, I'm sure you wouldn't know whether to grab your g=
un or a bucket of water.=20

With the voice siren driver you know immediately what the situation is.
