Random speaker pop on NetworX home alarm

[MattJ]

At least once per day, the speaker of our alarm system will emit a loud
pop. It's just a single pop. It sounds as if the speaker is releasing
a buildup of static electricity or something. The systems is about 8
years old. We've recently had the basement finished and they simply
built a frame around the control box. I believe the proplem started
occuring after the basement was completed. Any ideas what might cause
the pop?

Chances are your speaker is combination siren/driver and is supervised
by the alarm control panel. This means that there's voltage on the
driver circuit. The "pop" may or may not be "normal". As with anything
electronic, you may have to replace the siren/driver unit. What make
and model is your system's main control and how many siren's/speakers do
you have??

read the header again Frank its a Networx panel. May be a bad battery?

 

[MattJ]

I've had the security company out to try and fix it. They replaced the
battery two days ago. Pop still occurs.

Replace the battery.

Same time every day? Anything else happening at about the same time?
DC Voltage applied to a speaker would make a pop like that.
I think you're right to be suspicious of the carpentry. Can you check the
wire to the speaker? Rap on the wood near the panel to see if you can
reproduce it.
I bet Bob Lalonde could find this one

what kind of frame around the control box?...maybe they tagged a wire with a
nail/staple/screw

I'd tend to wonder if the workers rerouted any power wires near the
panel, speaker, or any interconnecting wiring, and if that power wire
runs something that draws a lot of power.

Try to figure out if the pop coincides with the switching on or off of
any appliances, such as the fridge, or an electric (baseboard) heater -
anything that could produce a voltage spike when toggling power. It
doesn't even necessarily have to be something located near the affected
components; all it needs is for the power feed to that device passing
too close to the alarm components or wiring.

When programming the system from the keypad a pop is heard at the end
of the programming. This is normal. It may also be true when
programming through the downloading feature. You may find that this
pop may also be associated with a daily test signal sent by the panel
to the central station -- and the system is programmed to emit the pop
at that time. I do not have my manual handy so I can not verify it.
Check with your monitoring company to see if there is a correlation
between the receipt of the daily test signal and the pop.

Find out if it's a speaker or siren, the NX can do both. If its a speaker
replace it with a siren and have them make a slight change in programming to
account for the siren

So....then, you get a siren blast instead of a pop?

It's just a hunch he won't, I couldn't think of anything else except replace
the board

Thanks everyone for your feedback. I will check these things out and
let you know what I find.
