new install on a DSC PC1555MX and when I powered up , nothing from the keypad . cabling all seems to be correct , I followed the instructions hooked the battery up first then the power . went to the keypad blank .
checked for power at the outlet and it was good .
any thoughts ?
bad board ?
bad keypad ?
second when setting up zones with N/C contacts why would I want to use the resistors ?
it gives me the choice of using a 5600 resistor or not
whats the reason /advantage in using them ?

On first time power-up, the AC must be present otherwise it will not turn-on (battery will not matter). With a volt meter, double check the 16VAC on terminals 1&2.
Also, those panels have fuse-less protection. Any shorts on the 12VDC "aux" or keypad will cause it to appear dead. Remove all DC lines and start with only the keypad and work your way up. You can also meter the red and black at the keypad to see if the DC is present.
The EOL resistors are a good idea, but they will only work if installed at the device, not the panel. The obvious benefit is nothing can short the line and "fool" the panel into thinking everything is okay, be it man made or building induced. That panel can indicate a short to building ground as well and report that to the monitoring station if required (this only works with EOLR in use).
Cable shorts can occur even down the road. I've seen misfires with the T18 staple gun cause a short a couple of years later. Also building settling, nails, and duct work shorts.
On normally open devices, the resistors constantly supervises the wire. On this type of zone, a broken wire could go unnoticed until it's too late.
On contacts, the resistor can be a PITA, but you get good at concealing them. You can also order contacts with the 5.6k built right in to them.
A little trick for concealed contacts that I do; using quad wire for the contact, wire the contact up on yellow/black and B-connect or twist the red/green together (bumble-bee/Christmas tree). At the panel, install the resistor between the red/black with B's and wire the yellow/green under the zone terminal.
If you think about this, the resistor is still at the end-of-line, even though it is taking advantage of the room in the panel box!

thanks Simon makes sense , I did check the AC outlet but didn't check the power at the panel it was getting late and I had had enough for one day finally got it all wired , powered it up and it was supposed to WORK !! ![laugh laugh](/forum/images/graemlins/default/laugh.gif) .

We always put the EOL's in the panel on the fire alarms we install using the same method. I HATE walking around searching for the EOL on a system someone else installed and there never is any paper work left behind.
Sometimes I think companies do that on purpose so the customer will grow tired of the time it takes for a new vendor to get acquainted with the layout of the system.
Skip, along with the advice Simon gave you, you may want to hook the keypad directly to the motherboard to make sure it's ok. But it may also be the motherboard if it doesn't work but this will eliminate the cable entirely. You may have to take the keypad and panel back to the supplier and have them tested. :confused:

Dang, you guys are allowed to do that? It's against code here on fire panels. We aren't allowed to bury the EOL though so it is always on a labelled wall plate.
Another trick on DSC; if you don't have the 16VAC available for some reason but want to power the panel up and run it from the battery - just take a couple of jumper wires and feed the 12VDC battery into the AC input terminals (1&2, polarity doesn't matter) for a couple of seconds. The panel will now run on the battery input.

back on site today , I took the keypad and wired it directly to the panel , display came up , went through told me what zones where trouble , (doors windows open )
tried programing and it would let me into programing but didn't seem to let me enter anything. finally display went blank , just yellow trouble light .
I powered down and removed the battery thinking it might clear it
powered back up same problem so I pulled it of the wall and brought it back here to work with .
for the n/c zones I can just bridge them , Right ?

Skip..you can bridge them with an EOLR

If this is an LCD keypad and you have it wired up directly like T.T. mentioned, with no display at all, sounds like a bad keypad (I've had it happen).

Skip, the zones are always going to come up in trouble on that panel at the initial power up because there is a fire zone enabled by default and the zones are also set up for EOL's by default and it sounds like you are trying to use normally closed loops and switches. Edit: I was mistaken, this panel does NOT have a fire zone programmed by default. Sorry for the false information. It sounds as though you are entering base level programming successfully but you aren't quite entering the correct commands and the panel is timing out of programming.

It is LCD keypad
I had the display but I wasn't able to program anything
couldnt set the time or date
. I was trying to enroll the keypad , the manual says it must be in slot 8 but then the manual for the keypad says slot one .
I was trying to assign it to slot one when I lost the display . and just had the yellow trouble light .
I need to get this going by Monday so I have a little time to play .
all I want are 6 zones , zone 1 four doors delayed . the others all windows immediate . no phone call out. siren only
so for shop testing /setup an use the resistors to complete the zones ?

If that's a brand new system, it will default the keypad to 18 anyway (partition 1, slot 8). This doesn't affect your programming though.
It will default to EOLR on, so yes, you can just loop out the zones using the resistors for testing on the bench. Again, this doesn't affect your initial programming.
I can't figure out why you lost the display though. There is a "power save mode" on those that will blank the keypad to save battery when the AC is missing after a certain length of time. This is also normally defaulted as off and even if it was on, by pressing buttons, the display should come back.
I would hook it up on the bench and go in right away and do a software default on the panel and then do a software default on the keypad.

Which keypad are you using? The LCD5501Z or the LCD5500Z? When you change the keypad address in the software you have to change it on the keypad with the dip switches on the back of the keypad. It's been many years since I fooled with the keypad address so I'm going from memory on that and I can't find anything about the keypad settings in the manual. I leave them all at factory default for the most part and it's never been a problem. Help us out here Simon 'cause I'm out of date on that stuff. :confused: As far as the resistors you have a choice of using them or not but I think it's better to use them. The controlling factor is which switches you are using, N/O or N/C or both actually. A helpful tip: When you program the zones you have to program all 6 zones. Any zone that you don't have anything hooked to should be programmed as a "Null" zone by entering 00 for that zone. LoL Simon must have been typing at the same time but he's faster than me. I think I'll sit back and let Simon take the lead on this one because he's definitely more up to date on this system that I am and I don't want to add to the problem. ![frown frown](/forum/images/graemlins/default/frown.gif)

set it up on the bench , same thing , display flash's briefly at power up then yellow trouble light solid, keypad is lit but no display , to initialize the keypad I need to go to installer program which I obviously cant do .
I tried to default the panel with the jumper from Z1, as per the manual but same thing . so off for a replacement
its new kit rf5501-433 keypad (no dip switchs) . PC 1555mx panel

You have a bad keypad.
No dip switches on DSC, no initializing keypads, just assigning.
Not assigning won't affect what you are doing, as a matter of fact, with single keypad system, you don't have to assign. The panel will find and assign it automatically as an 18.

took the keypad back and that was it . new one came right up
looks like I'm almost there
right now I have all zones strapped with resistor but Even in the ready state I get a alarm if I break the connection .
What am I missing ?
we should be able to open and close doors and windows leave them open .
now I have to enter my code to disable the alarm

In Zone Programming, section 001, you should have your delay door defined as 01 and the rest of your windows as 03 (instant). This will cause the ready light to go out when you open the strap, but not cause an alarm unless the system is armed.
