What panels work on 50 HZ that I can buy now?

[DaveInPNG]

I live in Papua New Guinea (near Australia) and it uses 50 HZ (50
cycle) power. I can get a 240 volt alarm transformer and indeed all of
the other parts I need cheaply in-country EXCEPT an alarm panel.

I can get a 6-zone panel of $200 US, but it's a panel that sells in the
US for $25-30 and that much of a mark-up bothers me (no battery or
transformer, just the panel).

Here's my question: What current model panel can I get in the US (6-8
zone) that will run on either 50 cycle power or is crystal controlled?

I'd love to hear your suggestions.

Thanks ahead of time. You've been a great bunch so far.

BTW: The source of the panel doesn't need to ship it to PNG, just North
Carolina. Also, Australia doesn't sell panels to non-licensed
installers so that is no option.

Always used to, try www.das.com.au they should be able to help.

Here's a simple straight forward solution for you. Get yourself a 16 VDC
(yes, "DC") power supply (compatability with your particular electrical
requirements shouldn't be a problem) and hook the outputs from this power
supply to the *AC* input terminals of the alarm control. If you're using
DSC, they're equipped with a full bridge rectifier so this *will* work.
Hook up your battery in the normal manner and "voila"...

My understanding is that most panels us the AC line frequency as a
timebase, therefore settings for 50/60 cycle or warning such as "won't
work below 55.5 cycles". Therefore using a DC source wil not work.

Well... I have a customer that's running a DSC 832 in his yacht... No AC
power available and I haven't had any complaints about the system time... I
just checked his account and the system is still transmitting test signals
at 0215 hours daily... I'll ask him if he's having to reset the clock every
once in a while...

Napco allows you to choose 50 or 60 hz or have the panel select
automatically.
