Hi,I have an alarm in our new (to us) house. In time I will have it replaced with a better system but for now it'll do.
I have the master code but no engineer code. I need to move one of the PIRs so need the engineer code.Thanks to this site, I have determined that the alarm is an Ademco Accord XPC. I have the engineers manual and tried the factory engineers code but to no avail. However, the manual says that the codes can be reset if I press some buttons within 5 seconds of power up.I have found the fuse for the alarm but am aware that it will have a battery backup. Is it just a matter of pulling the fuse, silencing the inevitable alarm and then putting the fuse back in before pressing the buttons?I would be grateful for any advice on how to proceed with the reset.Cheers.
Thanks - all sorted now. In case anyone stumbles across this thread in the future here are the steps I took.- I pulled the fuse in the mains feed to the panel.- The alarm went off and needed the Master Code to stop.- The 'Batt LED' symbol was flashing as the mains wasn't on.- I undid the 2 screws at the bottom of the panel and removed the cover.- The cover tamper activated the alarm but this was silenced by removing one of the battery leads.- I gave it a min or so before reattaching the battery lead. I had the cover in the hinges ready to close as soon as the battery was connected.- I press the buttons as per the manual.- The alarm sounded and needed the master code to stop (now defaulted to the factory setting)Both the Master Code and Engineers code were set to factory defaults so it was very easy to enter the programming menu and also reprogram my Master and user codes. Hi all, I inherited the above ADT Accord xpc a number of years ago, no contract and successfully replaced the battery in 2011. Recently a low battery warning so new battery purchased from, engineer code entered, new battery fitted only this time when exiting programme mode, the correct symbol for day mode (an empty circle) appears but when any movement is detected the beeps start and the alarm triggers. This stops when the user code is entered but starts again once movement is detected. So it's acting like it's in full set mode but the display says otherwise.
Now sitting in engineer mode (flashing spanner) to stop it triggering. Pretty sure the tamper switch is in the correct position too. Thanks for any help or suggestions. Hi, Really excellent info.
On this thread - many thanks. Thread is several years old but helpful for me despite it's agedness, and may help others with older ex-ADT systems featuring the Accord XPC. Hence, Administrator, please keep this thread open, it was a God's send to me!I just want to add a few observations on this issue described above. That is, replacing an ex ADT installed Accord XPC battery.Background: After 9 carefree years, following the cancellation of my ADT subscription, the internal alarm, positioned near the key pad in my hallway, sounded late one evening although the the alarm was unset. Not the usual power cut alarm, but much more intrusive and noisy sound. The battery icon was also flashing (no mains power-cut issues at the time) on the keypad.
The user code was subsequently entered and all was well - until later at 2:00 am, when the alarm sounded again! User code again entered, and this temporarily halted the alarm, but just for another 2 hours. On each occasion it was the internal alarm that sounded (i.e not the externally mounted wall alarm and 'strobe') accompanied by a flashing battery icon with a cross through it on the keypad.
After the latter episode at 4:30 am (arrrgh!) I started an online internet search which brought me to this really helpful page.Actions subsequently taken (5:00 am!) were: removed (pulled out) main power fuse from the the holder (alarm sounded and user code entered again to cease); removed the two bottom screws from panel covering the main CU box, in the garage, and lifted off the front panel (external alarm sounded as tamper switch triggered); and then I quickly removed the back-up battery leads - resulting in all being quiet and keypad unlit. That is, whole system switched off.This other webpage was helpful for a free download of installation manual (I don't have ADT's Master code or Engineer code) and as yet haven't needed to use these but this manual shows option for resetting to factory defaults of master code 1234 and the engineer code 9090, if needed in the future.Replacement battery was.Power Sonic PS-1270 F1 12V 7AH Battery - Diamec DMUF12-7.6 Batteryordered at lunch time from (starterbatteries) - £23.00 plus free delivery - and delivered 10:00 am the next day. Excellent service.Ok, here are some additional observations from the steps indicated in the postings above for reinstalling the back-up battery.1. Hooking up the new battery sounded the internal alarm, which was stopped by entering user code (yes, the system hadn't 'self-defaulted' to factory setting which I had wondered about).2.
CU box front panel reattached3. Mains fused pushed back into the fuse box.All seemed well, but.the keypad had a bell icon flashing (in the top left of the display) in addition to the day circle. Also, while I could enter 'easy-set' and/or user code plus press the full-set button, the exit countdown continued, that is didn't stop after the usual 20 secs before the alarm was set. In fact the alarm didn't set at all so obviously none of the PIRs or the front door contact functioned.
The user code stopped the endless count down bleeps.The Manual suggested that the 'bell icon' was the tamper switch, inside the CU panel.So. I removed the main fuse again (alarm sounded - user code quietened it); CU panel unscrewed again and lifted off (no alarm this time!!!). After some head scratching, I eventually realized that the tamper switch (this is a spring loaded, plastic 'stalk'-like protrusion, in the center of the panel) had not engaged properly with the small circle moulding, on the underside of the CU front panel.I pushed the tamper switch in towards the circuit board and then tried to engage the end of the plastic extension into the circular area on the front panel. Obviously however I was successful, as once the panel was screwed back in place, and the main fuse was re-engaged so that the power was back on, the keypad was also back to normal (i.e no bell icon flashing- just the day circle showing).With fingers crossed, I then reset the alarm (using easy set) and all worked well. That is, a 20 second count down exit period, before the alarm was set.
Opening the front door also gave me a 20 second 'window' to unset the alarm with the user code. So far, all seems well and no costly need for an electrician, plus a glowing sense of achievement - we all need these small victories in our lives!Once again, massive thanks to this forum and particularly to this thread.
Hi,I have an Accord XPC installed on my home. It`s a few years old now but has worked faultlessly until now. I got the user manual and install manual and noted install settings, most are default and no comms connected.
There`s no fault find info in those.I set the alarm and left home but on my return a day later I couldn't unset the alarm quickly as I was carrying in boxes and equipment. (I sometimes do that and just reset the alarm.) The alarm set off. It can siren up to 20 minutes by default if left and normally sounds off until its reset at keypad.But after 20s or so the siren and strobes just cut out. The keypad has an audible alarm and that kept buzzing, so it was still alerting armed.I user code the alarm to stop/off, then again reset the LCD to clear the zone entry point notification.All seemed fine except I got the flashing bell icon never seen before - Tamper Check +09.Right so I thought lets do a system check - user code +5.
It cycles the strobe/bell for 5 secs then the zone walk through in order 1-4. I get a Ce fault on the bell box but the rest cycles through fine.I set the alarm again and tried to trigger it, no bell box /strobe activation, the LCD and internal buzzer activated as per.So my thinking is the bell box gave out under load when it was set off, lasted for about 20 secs then went kaput. The fact that the test cycle gives the Ce code points to the bell box or supply to it? Its now acting dead and the passive state LED indicators are off too.
I assume I`m getting the Tamper Check +09. Error code icon because the system cannot communicate with the bell box and shows a tamper error?I notice there`s a F2 Speaker/Bell:500 mA, 20 mm, Anti-surge. On the panel pcb for the bell box so I was going to cut the power, disable the battery then examine/replace the fuse as a start. Then check the battery for 12v+. Whats worth checking on the bell box itself? Water ingress, corrosion?I`m no alarm engineer but worked in m.v.
Ademco 4140xm User Manual
Electronics before and I know pcbs and control systems do not like water or corrosion and all sorts of error codes can appear!Anyway, now the alarm will not arm at all. Normally it does the 30s delay before setting, now that delay continues indefinitely without arming it. It didn't do that yesterday though.There is a Group 4 — Option 9 Prevent Setting for Power Fails. But that is set to default 0.Mains fail.
And the mains supply is fine. Its internal, secure and sits below the consumer unit in a dry cupboard. I asked the neighbours and they say its never been set off while ive been away. Its been relioable.Any advice welcome. If I needed a bellbox or battery wheres best place to buy them?Regards.
