  • Anyone Install Home Alarm Systems?

    First, I want to mention that I have already found the DIYHomeSecurity Forum, and have posted there, but wanted to check the XS11 mindtrust!

    I'll try to keep this as brief as possible...yeah, right!

    Had previous system...Honeywell/Ademco Vista-15P with 6150RF wired touchpad. Changed monitoring company 2.5 years ago(now 5 yr contract ), received a newer Control Panel/system..same brand LynxR2 with a wireless touchpad 5828V. We didn't use the system much...SWMBO didn't like it, etc. Seemed to otherwise be installed and work...no faults showing on touchpad, but had set it to quiet mode months/years ago so opening/closing doors wouldn't produce a CHIME, etc!

    Then had laminate flooring installed in the Spring, in hallway just in front of hall closet where alarm system is. Noticed shortly afterwards that the READY to arm light wasn't on/green! And so called the monitoring company, they called a local service tech (old fart), came out to look at system. The newer Wireless sensors that came with the new system were for the outside garage door, and 3 sections back bay window. The OLD system had 4 hard wired sensors...inside garage door, front and back doors, and large flat back window. The newer touchpad reported a fault on one of the sensors...allegedly the outside garage door.

    Service tech checked, it, changed batteries, then swapped in new sensor, etc., but couldn't get system to clear the fault!? Said it would be something like $350.00 to install other wireless sensors for fault location,etc.! I said "BYE".

    Okay, started by troubleshooting wired sensor, found open circuit for inside garage door....found wires cut in frame...crawled under house and pushed up more wire, reconnected, and circuit now worked/checked okay for continuity. Checked same for other 3 wired circuits, and then labelled the wires appropriately...the old fart tech had cut ALL of the hard wires from the older Vista Control panel !!!

    See following pictures...we all like pictures!!!







    The newer Lynx control panel was connected to the phone line, and we would get a call from the monitoring service(did today when I was working on system); a tamper code was sent, told them to put our monitoring status on TEST for 24 hours! Found that the Old Vista CP wasn't even connected to the AC power supply, just the backup battery! I think one of the wired circuits on the Vista CP was connected via wires to a Wireless sending unit..it can use a magnetic sensor or a wired/switch, and I think this was how the old system/hard wired circuits were being monitored by the new system, all thru 1 wireless sensor connected to the main terminal for the old wired sensors!?

    Anyways, trying to figure out how to be able to preserve the old wired sensor circuits, and have them monitored by the new wireless LynxR2 system, but from what I just wrote, I may have just figured it out myself?

    The installation/programming manual is written in technospeak, very hard to understand for the lay person. But I remember reading something about the wired circuits being able to be put in Series, so that they could all be connected to 1 monitoring zone instead of each switch being a separate zone!? But they were still wired to the Old Control panel just like they were when it was being used, aside from the extra wireless sensor? I'll have to look at that terminal switch closer...the installation instructions specify certain locations for a resistor being put on one of the 2 wires for each circuit, something about the circuit not being able to be monitored without it??

    So...any system installers with any other ideas about how to keep the wired sensors in the monitoring loop without just adding additional wiresless sensors for each location? I won't necessarily care that the front/back/garage doors are all on 1 sensor/circuit/loop...the house is relatively small, and with the alarm set to Home/instant....it'll sound anyways...just what we want!?

    Thanks in advance for reading!

    Yes, you can series the sensors, just be sure to use only ONE end of line resistor for each zone. Trouble with using multiple sensors on same zone is figuring out which door is open when you have a not-ready condition, but you already knew that

    We don't do much residential, but mostly hi-rise commercial systems.

      From looking a manual for a Lynx system http://safecoalarms.com/Portals/_def...mages/Lynx.pdf it looks like Zone 1 is for hardwired devices. Check page 8 of the manual and you will see terminals 6 and 7 are Zone 1. Wire your sensors in series on the + line and install a 2k resistor across the + and - on the end of the line. The alarm wont know which sensor has tripped but it will generate an alarm to the monitoring company.

      One thing though, not all Lynx systems support a hard wired zone, so you will need to confirm that yours does before getting too deep.

        Consider this thread closed/completed!

        Hey Davinci and Walker,

        Thanks for the input. The newer system is actually a LynxR2, and doesn't use any hard wired connections for sensors, just for things like controlling houselight switches and such.

        I had the 5816 wireless sensors, connected a pair of wired triggers in series to each wireless sensor...but no EOL resistor needed....they do not provide supervised circuits on the wired loops for the 5816 anyways. I was worried about programming it, but thankfully the previous initial installer of the LynxR2 had programmed it correctly, and once everything was connected, all of the sensors reported and were received.

        The 3 bay window wireless, the front/side door wired/wireless, the back door/window wired/wireless, the outside garage door wireless, the smoke/fire detector wireless, and the break glass sensor wireless. Full testing was successful, touchpad response, Away and Stay modes, etc.!

        I'm a happy camper and will be feeling much more secure now that I can actually USE my alarm system again...since I'm paying a monthly monitoring fee anyways!!!! And also $350.00 was saved from my bank account! I was off work for Xmas vacation as well....so actually was getting paid !
