Digital Security Controls (DSC) - Power632 (Circuit Board PC1555MX) - How to Change the Master Code Shared Knowledge ' Digital Security Controls (DSC) - Power632 (Circuit Board PC1555MX)' 'How to Change the Master Code' 27 March 2011 Summary: the 'Master Code' is used to add, edit or delete user defined access codes (arm-disarm) for the Digital Security Controls (DSC) Power632, (circuit board PC1555MX) home security system. The PC1555MX ships from the factory with the 'Master Code' of 1234. As the default 'Master Code' is public knowledge, it should be changed such that someone could not enter your home and using the default 'Master Code', disarm your system. To change the 'Master Code' you must know the current 'Master Code'.
Background: The Digital Security Control (DSC) Power632 security system (circuit board PC1555MX) has non-volatile memory (does not loose contents when power removed), which holds various security system definitions. There are two critical stored codes per Power632-PC1555MX: 'Installer Code' and 'Master Code'. The 'Master Code' is required for any add, edit or delete of an access code. The factory default 'Master Code' is 1234. The 'Installer Code' is required for PC1555MX programming.
The factory default 'Installer Code' is 5555. As the default 'Master Code' is public knowledge, it is advisable to change this code so someone with DSC knowledge could not enter your home, key in the 'Master Code' and disarm the system.
Both the 'Master Code' and 'Installer Code' can be changed and could have been changed by the previous homeowner or by the system installer. You must know the current 'Master Code' or current 'Installer Code' to change the 'Master Code.' How to change the 'Master Code': At a DSC keypad: Enter ✱ 5 'current 4-digit Master Code' (if you do not know of another code, enter the default 1234) If the entered 'Master Code' is valid, the DSC keypad should light the 'Armed' light emitting diode (LED) and show 'Program' on the display.
What your keypad will do exactly depends on the model of your keypad. Now enter 40 'new 4-digit Master Code' # # The 'Master Code' must be 4-digits long (0-9) (Will accept 4 '0's' or 4 '9's'). If you are successful in changing the 'Master Code' make sure you record it and keep it with all other security system information.
Keypad will not go into programming mode: If when you enter what you think is the current 'Master Code' the keypad does not go into the programming mode, either the PC1555MX has the 'Master Code' locked or the 'Master Code' you think you know is invalid. If the know the current 'Installer Code' (default 5555) you can attempt to see if the 'Master Code' is locked and unlock it. To unlock the 'Master Code'. 8 'Current Installer Code' 015 On an liquid crystal display (LCD), if the ' 6 ' is showing, then the 'Master Code' is locked.
If the 6th light emitting diode (LED) on an LED display is lit, then the 'Master Code' is locked. To unlock the 'Master Code' press the '6' key and then ## If '6' is not showing in on a LCD display or the 6th LED is not lit on a LED keypad, then the 'Master Code' is not locked and the 'Master Code' you think you know is invalid. To attempt to set the 'Master Code' via the 'Installer Code':. 8 'Current Installer Code' 991 ## (Default 'Master Code' = 5555.
This will attempt to unlock the PC1555MX, if locked). 8 'Current Installer Code' 007 'new 4-digit Master Code' ## If you are successful in changing the 'Master Code', make sure you record it and keep it with all other security system information. Can not change ' Master Code': If you attempts to change the 'Master Code' fail then you do not know the current 'Installer Code.'
Your options at this point are: - Contact the previous homeowner and try to get the current 'Installer Code.' - Contact the security company that installed your security system and ask if they have the current 'Installer Code' in their files. If you learn another 'Installer Code' you can attempt to repeat all steps above with 'Current Installer Code' - If no matter what you try, you can not get the PC1555MX to go into the programming mode, you must either do-it-yourself replacement of the PC1555MX (replacement boards available on eBay and other Internet websites) or pay a security system company to replace the PC1555MX board for you.
I’m the 2nd owner and the previous owner did not leave me with code nor a manual book. I did a search online and found me the manual but it doesn’t help me with the problem I’m having. I think I have a Classic PC1555/PC5508 LED keypad with 8 zones. I have no service with security company since I moved in 2 years ago. A few weeks ago the trouble light came on and kept beeping. I pushed.2 and Zone 1 light is on indicating the front/garage door.
I closed all the windows and doors, still trouble light. Last week I came home after work open the door the siren went off.
With me not having a master code I couldn’t do anything to stop the siren so my b/f cut the wires. Now, I all the zone lights are blinking, armed and trouble light are on.
How to disarm with no master code? How do I fix this problem? Ok, first, you are misinterpreting the trouble indicator display. You can get the user manual from, which will give you the proper truth table for the trouble display.
(1 showing after pressing.2 means the the main system battery is low or dead) To properly shut the panel down, go to the battery cabinet (usually located in places like the master bedroom closet), find and unplug the power transformer (generally in an outlet somewhere relatively close to the main cabinet), and unplug any 1 of the wires on the systems backup battery. This will completely shutdown the system. Power back up, AC power first, then reconnect the battery (after repairing any wires that were cut). If it comes back up armed, then the only thing that can be done, short of a lucky guess at the master code, is to default the thing (which doesn't have a 100% success rate). Read the FAQ for this forum, and some of the other posts talking about DSC Power series panels (1555/power 632; 5010/power 832).
Just realize that if you have to go the default route, DSC panels are not very DIY friendly. You lucked out. These are often setup to power back up in the same state they were in when shut down.
The program light is an indicator for a number of functions. The zone information does not have to be reprogrammed at this point. Just press # until it returns to normal run mode.
The first test: Once in normal run mode key in:. 8 5555 If it beeps rapidly for a few seconds and the program light comes back on, then the factory default installer code will work, and resetting your master code will be easy. Just hit # until the program light turns off, and let us know, and we can help you from there. If not, things get a lot more complicated, because short of a lucky guess at the installer code, the only option is defaulting the panel, which will mean resetting all of the zone information, among other things. First: go into program mode:. 8 5555 The zones are all showing open because the original installer didn't want to install zone resistors, so you need to turn that requirement off. Enter 013: zone lights 3, 6, & 7 should be on.
Press 1, and that zone light should turn on. Press # The default also turns the dialer back on, which you will need to disable if you will not be monitored: Enter 015 press 7 to turn off the telephone line monitor press # Enter 380 press 1 to turn off the communicator. Press # until you go back to run mode. All that is left after that is to reset your zone configurations.
I hope you figured out which zone corresponds to what before you ran the default procedure? Hoookay, first of all, exit (press # as many times as it takes) all the way back to run mode. The various lights mean different things depending on what commands have been entered, so simply describing the lights that are on tells us nothing. Next; to help you do this, you have to tell us what zone is supposed to do what on your system.
There is no universal template, security systems are essentially custom installations. Ignore the memory light in run mode, it just means that you haven't armed the system since the last time it was put into alarm. Let's start with a listing of what your zones are supposed to be. DSC panels are complex, even as security systems go. Most changes involve multiple commands. Posted By: sow sow Ok here are the listed zones: 1) Front - Garage door 2) All windows 3) Back door 4) Master windows 5) MotionAlrighty, now we have something to work with.Assuming that everything is hardwired and not wireless.
enter program mode by entering. 8 installer code. go to secton 001. Enter the following codes: 01 03 03 03 05 00 00 00 (this sets zone 1 as an entry/exit delay; the windows and back door as instant alarms; and the motion detector as an interior zone that will automatically bypass if you do not open and close the entry/exit doors during the arming delay) The only other thing left is to set a new master code which you can either do directly from section 007, or by using the keypad commands after you exit to run mode. Unless there's some other obscure feature that's causing you issues, if you don't have a ready light, you might have to figure out which opening has a missing magnet or damaged contact.
Often, a new battery will still need several hours of charge time before the system registers that it's charged enough. As much as overnight in some cases. Also, trouble 1 is more than just battery. Look at the table in the install/user manual: Service Required: Press 1 to determine the specific trouble. Lights 1 - 5 will light up to indicate the trouble:. Light 1 Low Battery: Main panel backup battery charge is low (below 11.5 volts under load).Trouble is restored when the battery charges over 12.5 volts.
Light 2 Bell Circuit Trouble: The bell circuit is open (see section 5.13 “Bell” on page 23). Light 3 General System Trouble: The printer connected to the PC5400 Printer module has a fault and is off-line. Light 4 General System Tamper: Tamper has been detected in a module. Light 5 General System Supervisory: The panel has lost communication with a module connected to the Keybus (see section 2.6 “Supervision” on page 5). The event buffer will log the event. NOTE: All tamper conditions must be physically restored before the trouble condition will clear.
NOTE:Lights 6-8 – Not used. Hi MrRonFL, I was just reading the post regarding the yellow trouble light with the alarm dsc 1550 system as I am having the same issue. I switched alarm monitoring service and the tech person came to reprogram the main board and since then the trouble light has been on pointing to low battery. He replaced the battery today and the light is still on. The tech person is saying not to worry about it and to leave it as is. I do NOT like to see it like that and would like to know if it can be fixed.
Actually there is another master installer code. I found a local guy who gave me a installer code for systems installed by private companies. I will have to look up that code because I dont have it in front of me, but there is another code other than 1234 or 5555. I also have another question. I want to hook up an external siren. The output of the bell connection is 700mA.
I have an inside bell also. The new siren that I have is 15 watts at 12V. Where in the panel can I hook this up so that I have a siren inside the house and one outside? There are numerous installer codes. Nearly all installation companies have their own.
The codes I listed are the factory default codes for a non-modified system, and are the codes that the system will revert to if defaulted (assuming that the installer lockout feature is not active) Common codes used by businesses include: the last 4 digits of one of their phone numbers, the business street address, the last 4 digits of the business license, the street address of the installed system. Common ones used by mass market installers include: 6321, 3800, 0852, 9713.
