Question Replacing an old Panel with PC5508Z

I have a security system wih two keypads. One keypad is a very old and basic and the other one is a new LCD5500Z. This has been working fine a quite sometime now. I got hold of a PC5508Z and replaced the old keypad. I connected the wires the same as they were connected in the old keypad. The keypad now displays "OPEN" and if I try to arm it or disarm it, it gives out a long beep/chime (about 2-3 seconds). Any idea what I am doing wrong here? Did I connect the wires wrong? Please help. Also, if there is an installation manual available online for download, that would be great since I did not get a manual with my PC5508Z.

Thanks,
AK

For one, if you changed the keypad with the system powered up, you were playing a bit of "russian roulette".

The keypads are electronically supervised by the system, and need to be enrolled and setup in the system programming. It sounds like you have a power series panel, but we need to know the specific panel model to help you. You also need to know the installer code for the system.

You are right. I did not turn the power off becasue I thought it was battery operated and didn't think much of it. But I agree that was a bad idea.

The keypad I installed is a DSC PC5508Z. Is there a more specific model number I need to get? I can get the installer code from the security company.

Strangely, the keypad appears to be working okay now. This happened overnight. The OPEN sign has gone away from my other LCD keypad and the long beep has gone away. The ready light and the armed LEDs are working too. Although I am not sure if the system resolved the problem by itself or just the symptoms have disappeared.

Please give me your recommendations on what I need to do the register the new keypad or if there is something I can do to test and make sure everything is working okay.

Thanks again for all your help!

The keypad is just an interface, that keypad is used for about 6 different system models.

You need to look in the cabinet where the battery and main circuit board reside. There is usually a diagram on the door with the model number, if not there will be one of the chips on the main PC board with a number like PC1555 or PC5010.

These systems have electronic circuit breakers called PTC devices, so, it probably cooled off and reset itself; they don't always come back.

Once you know the model, the user manual is easily available from www.DSC.com.

If you are lucky, the installer code hasn't been changed:
For the installer code, the default is 5555, you can also try 1555, 1550, and 6321

From an LED Keypad:
1. Enter[*][8][Installerís Code].
The Program light (or System light on the PC1555RKZ) will
flash to indicate that you are in programming mode.
The Armed light will turn on to indicate that the panel is
waiting for the three-digit programming section number.


From an LCD Keypad:
1. From any keypad, enter[*][8][Installerís Code]. The Keypad
will display ĎEnter Sectioní followed by three dashes.


If it works in either case, simply press # to go back to run mode.

To correctly enroll your keypad, from the new keypad, enter:

1. Enter[*][8][installerís code] to go to installer programming
2. Enter [000] for Keypad Programming
3. Enter [0] for Slot Assignment
4. Enter a two digit number (11-18) to specify which supervisory
slot the keypad will occupy. (in this case it would be 11)
5. Enter # until your are back at run mode.
6. Enter[*][8][installerís code] to go to installer programming
7. Enter [902] to set the module and keypad supervision to include the new keypad
8. Enter # until you are back in run mode.

That should be it.

Thanks for the instructions. I do have one clarification to make. You said that I should use 11 as the supervisory slot for this keypad. I do have two keypads. Can there be a conflict? Could the other keypad be occupying slot 11? Should I repeat this procedure on both keypads using slots 11 and 12?

Thanks!

The LCD 5500z keypad is slot 8 by default, and if there is only one such keypad in the system, it should be in slot 8 (that's where the system expects to see it), if you have it set for slot 1 or 2, it's not an issue as long as there is only the one LCD alphanumeric keypad in the system.

As long as both keypads are on different slots, you are good to go.

I am sorry if I misled you but the keypad that is already there is not an LCD5500Z. Instead it is an LCD5501Z Fixed Message LCD Keypad. Does that make a difference or does the system expect that one in slot 8 also?

Thanks!

In that case, treat it like one of the LED keypads. One of them should be 11 and the other 12.
