    Old 41A control, one zone, with shunt lock
    I've only even do crimes "against alarms" you've all seen pictures of my work....

    Tsi members remember police stations , they all hiding there DBs right now

    no, however I went with the scouts to a police station visit in 1980's aged 10 or thereabouts highlights where all the cool knifes handed in under an amnesty & learning the police could unwind after a hard day of forging paper ect... in their very own bar located on an upper floor.
  6. al-yeti started following Wiegand to OSDP retrofits: Anyone else seeing latency issues on existing old wiring? and HKC Quantum 70 Alarm - Full Set not working - not arming

    Does anyone recall in the 70s going into the police stations control rooms to work on the original direct lines to the police, seem to recall a large unit taking 10-20 modules, with red, green, amber lights on,, red for alarm, amber for line fault and green for clear, along with a toggle switch to silence buzzer. This was a private wire provided by BT direct from the police station to the protected premises. Be great to see any photos if you have any

    Morning gents, just a quick update on this one. As most of you accurately predicted, the client completely balked at the quote for pulling new shielded cable. Typical! Instead of fighting the 20-year-old 22/6 wire and trying to smooth out the OSDP latency, we decided to pivot entirely. We are pitching them a mobile credential solution (BLE/Smartphone) to bypass the physical wiring constraints as much as possible for the main entrances. We actually had to put together a bit of a primer for their management on how mobile credentials and BLE access control stack up against traditional cards just to justify the architecture change. I figured I'd share the link to the guide here in case anyone else needs some ammo to convince a tight-budget client to ditch legacy setups: https://www.civintec.com/Mobile-Credential-Access-Control-Systems-BLE-QR-Code-Solutions-for-Seamless-Security Looks like mobile/wireless is quickly becoming the only headache-free way out of these retrofit nightmares. Cheers again for all the input over the weekend!

    I'm sure you can balance it with different values. I'd test with different values and see but you might be able to calculate the swr. Can you add capicitance on the run? Your big issue is going to be reflection. Stick a scope on it and look. Or go back or recable

    Testing the 2

    You hit the nail on the head, @al-yeti. It always boils down to the budget. When clients want the high-end encrypted OSDP readers but refuse to pay for a proper cable pull to support them, we end up fighting these exact gremlins. Cheap wire always ends up costing more in labor! @james.wilson - 2.5 miles is absolutely insane! That really speaks to the magic of using proper Belden twisted pair. You are completely right about the termination resistors; I made sure we have the 120-ohm resistors fitted across the bus. It definitely stabilized the connection, but I think the untwisted nature of this 20-year-old alarm wire is just struggling with the constant two-way polling of the OSDP Secure Channel. Appreciate the sanity check from both of you. Guess it's time to have that tough conversation with the client: if they want that instant card read speed, we need to pull new cable. No magic tricks this time.

    Why the dualcom?

    I also do that and no i cannot. There is a mod to connect to the cloud service but polling is slow as its pulling from the cloud. I use output modules and an esp32 to get the events from my hkc 10270. I have wifi gsm on the app (and a dualcom)
  19. hootenanny321
    Yea, looking at the documentation online - the 4G/Wifi modules need minimum v4.4 I see there is also an Ethernet module available. Tomorrow I am going to phone around some HKC accredited installers in South Manchester and see if they would be happy to do ad-hoc service, or if push comes to shove I'll get a service contract. I am a Software engineer and love tinkering, so hopefully they'll be alright with me poking and prodding the alarm system, as I am curious if I can get Home Assistant to communicate with the alarm in the future once its on my LAN.
  20. james.wilson
    rs485 'should' have termination resistors. Might help if your cable is truly shocking. Ive run rs485 2.5 miles as a test in the ancient past but on twisted pair belden
  21. james.wilson
    Yes needs a firmware update very old software. You may also need to turn off some of thepolice options. As its a proper panel it is setup for police response out of the box. Also the 4g modules etd wont work without an update
  22. al-yeti
    I think the delays are rare tho mostly find they all open , I don't do much access , but go through plenty , ususally where the customer doesn't want to spend much is where maybe this problem will occur amongst other issues
  23. sanhaowangluo
    Haha, the universal 'get out of jail free' card! I might just have to use that if the client complains about the half-second card read delay. I was secretly hoping someone here had a magical impedance-matching trick for 20-year-old alarm wire, but I guess 'blame the sparky' is the gold standard for a reason! Enjoy the rest of the weekend, mate.
  24. al-yeti
    They would also need to setup your account However you would need to find someone willing to do it without a contract After all if they update your software, the 4g module you might find hard to get as no stolen ones in eBay yet lol Then you have the monthly cost of the app Will someone do it for a day rate , probably not , but maybe.....
  25. hootenanny321
    I am going to see if there are any installers who could update my software for me, then I can fit a 4G / Wifi module and use the SmartComm app.
  26. al-yeti
    Ok cool it will do a job for you then to an extent
  27. hootenanny321
    So when I tested it there: 1. Walked into Zone Lounge (Alarm) 2. Alarm triggered / panel bell and siren went off. 3. Went to control panel and entered code, immediately stopped (my neighbours probably hate me now)
  28. al-yeti
    By the way when you set your alarm , and trigger it as intruder , does it let you turn off the alarm straight away , or does it wait , set off the siren and then let you unset ?
  29. al-yeti
    Not really , the alarm wasn't really designed for a DIY user and ususally installed by alarm companies and installers Eg your software version is proper old , adding new devices will be troublesome , so you will probably only be able to use version 2 and below to make things work I don't think you can get the app system either without an installer or something one with access

    Thanks, I just had a nosey an looked in the System Overview On there it showed a setting called Infinite Exit - ON This peaked my curiosity even more and I went and looked in the engineers manual. I turned it OFF and now the alarm countdown works and it arms succesfully. Such a stupid thing to have turned on by default, wasted about 5 hours of my time, oh well. Thanks for rubber ducking
  31. al-yeti
    It's waiting for you to open and close the door , because system is set to final set on the door
  32. hootenanny321
    Long story short, a family member used to be in the alarm industry. They had a HKC 70 Quantum kit (2 x PIRs, 1 x Door contract, 1 x SABB) they gave me for free. I setup the alarm using the engineering manual. Here is what I have done: Setup 3 zones (Hall, Lounge, Kitchen) Added RF devices (PIR 1, PIR 2, Door contact) Assigned RF devices to each zone Door Contact => Hall Zone => Entry / Exit PIR => Lounge => Alarm PIR => Kitchen => Alarm Assigned two users (each with different codes) Added proxy FOBs for each user Did a walk test, all devices work, no faults Checked battery levels on all RF devices - 100% Timers - Entry / Exit - Unchanged (default 15 seconds) When I type in my user code and select "Full Set" it just has a constant tone and doesn't seem to arm, I waited 10 minutes until my ears started to bleed, but it wouldn't arm. However if I select "Quick Arm" and test the door contacts or PIRs, it works and triggers the countdown, or alarm respectively. The software version is : 1.1.10 Any ideas?
