I've lost the master key for my dsc pc500rk keypad

I've just moved into a new house. It has a DSC PC510 with a DSC PC500RK Keypad. The one problem is that the esate agent didn't give me the master code. How do I reset it and are can you use the default codes like 0550 or 1234?

My DSC Wt5500 Alexor Wireless keypad not keeping correct time even after changing batteries. Is there something in the programming I need to do to get it right? Thanks!

I am assuming that the keypad was successfully enrolled? Try to reprogram time. Time should be coming from the main unit and not the keypad itself.

Master Code
24 hour time (ie 2pm= 1400)
Date Format mm/dd/yy

Keypad should confirm successful entry by beeping rapidly three times

press # a couple times to get out of programming

After exiting programming the display should come up within 30 seconds or so displaying the date and time before it goes back to sleep.

Reset master code

The only way to reset the master code is with the installer code, which is generally set by the installing alarm company. I believe the default installer code is '5555'.

Just moved into new house. Plugged in DSC PC1832 to power outlet. Keypad beeps every 3-5 seconds and yield sign is lit. How do i keep it from beeping, and only beep when doors open?

This means there is a fault on the panel, either something very benign ( like the system clock is not set or a low system battery ) all the way up to a major configuration or communications problem. You can press * + 2 to see the troubles on the panel. If it is the system clock, you can set it from there and be home free. It is probably a good idea to have the local alarm company come by and do an inspection and test, though, as the communications may be down ( last tenant ended the monitoring contract, phone line may be disconnected, etc.) and you probably want to change the user codes.
