SurGard SG-411SM Home Alarm System
Hi Everybody,
I just moved to my new place and there is very old alarm system (Surguard SG-411SM).
Nobody know how to use it. It seems, it is ready to work. There is no instruction for it.
I need instruction to activate it.
Thanks
Sam

I couldn't follow or find your non-link for some reason, but I'm pretty sure I've never seen that model. As far as I could find with my limited searching skills, that model was marketed in the late 80s-early 90s, a boom period for the alarm industry, when everybody and his brother seemed to be getting into making panels. Only a few got marketed widely enough to become well known.
From what I've found from old alarm forum posts, the Surguard SG-411SM was a hardwired system with only two burglar loops: Time delayed (for entry & exit) and Instant. And if you had an alarm, there was no way to tell what opening caused it. Even in the late 80s-early 90s, that was pretty primitive; even then, being able to divide a house/store into 6 or 8 zones was considered minimal for a hardwired system.
My best advice would be to upgrade to an inexpensive modern panel and keypad(s). Question, is/are the cables connecting the keypad(s) 2, 4, or more wires? A picture of the wiring inside the Control Box might show the possibility of dividing the sensor wiring into multiple zones.
As I said, I've never come across this model myself among all the obsolete one-offs I've worked with, but I worked ~40 years in the D.C. Metro Area and the Surguard SG-411SM might have been a local phenomenon in your area. You might wait for some of the other techs to weigh in.

Sur-Gard was the branding the DSC used for their line of central station recievers. It's possible that a local installer was using a similar name as a DBA. Without a picture of the alarm control, it's hard to tell what you are dealing with; but it sounds like a pretty early system.

Hi,
Thanks for your reply. Here are some photo's of alarm system that I need help with.
How to operate it? How to change the code?

Yup, that's as old as I thought. Even my "way-back machine" archive doesn't have anything useful. For systems like that, those keypads were an add-on part; and the code was programmed into the keypad itself. I _think_ there is a simple way to default the keypad and program a new code; because those are pretty similar to the keypads still being used for access control.
In my opinion, even if you get this thing working, it's probably not going to be very reliable.
If I remember correctly, a momentary short from SW+ to the output ground arms and disarms it. That black plug is a spot for a key switch; and the keypad is just an advanced contact closure switch.

Thanks for your respond.
I believe It will be wise to do not do anything before getting good understanding of system.
