Hey Guys, I have a few newb questions. Firstly,do I only need to put resistors at each sensor (EOL setup)? I’ve read the manual, but it doesn’t specify this… (I’m about to use a Satel Versa 10 panel.) Or is there other places in an alarm system where resistors should be put? Am I right thinking I need 1 resistor, in series, at the furthest part from the panel (for example in the housing of each sensor)? Which wire should have the resistance? (The Alarm one, in this case it’s called „NC&C”(?) NC&C both signyfy that no R is needed don't they? ) If it’s a combined sensor (PIR & glass breaking) then do both NC&C inputs need a resistance added at the end of the wire? What if the sensor has an input called „EOL”? Does that mean that the resistance is included and no need to add one to that input or that i need to put the wire with resistance into that input. Secondly, what resistance should I use? I heard of using 3.3k Ohm, DSC panels use 5.6 kOhm AFAIK others 2k2... Is that specified with each brand/panel? Is smaller resitance better? It’s mostly to learn and for DIY fun, so that’s why such a newb doesn’t get professional help.( Introduction ) Thank you very much for your help, I am getting quite confused, as you may have noticed
Hi All Hope you are all well. I hope i am posting my query on the correct thread. I would dearly appreciate any advice that is provided for my query. I recently had a Honeywell Galaxy G2-20 installed by my uncle. He has only installed a couple of these Honeywell alarms previously, however he is stumped on a certain issue. My setup is as below. 1 X Honeywell Keyprox MK7 CP-038 Keypad (Address 0, Downstairs) 1 X Honeywell Keyprox MK7 CP-038 Keypad (Address 1, Downstairs) 1 x Honeywell RF Portal (Address 4) The issue that i currently face is that the only functioning keypad is downstairs. From an overall perspective, the alarm functions fine with the keypad installed downstairs. I can set & unset the alarm fine. The issue is that the upstairs keypad and the rf portal do not function when connected to the power supply. The upstairs keypad led is rapidly flashing with a green led and flashes with many stars, eg. ***************************************. The keypad was beeping when installed, however the esc key was pressed to silence the audible keypad beeps. The rf portal is not connecting correctly via the data line. I have come to the conclusion that the communication link has not been wired up correctly. The current setup has the A & B from the keypads & rf portal connecting directly on to the A & B data bus on the G2-20 panel. It is not daisy chained. Are my assumptions correct? Also the last connection (rf portal) does not have a 680ohm resistor connected between the A & B. Should the setup be like this? 1. Alarm Panel Data Bus "A" -> Keyprox Keypad Downstairs Data Link "A" -> Keyprox Keypad Upstairs Data Link "A" ->RF Portal Data Link "A". 2. Alarm Panel Data Bus "B" -> Keyprox Keypad Downstairs Data Link "B" -> Keyprox Keypad Upstairs Data Link "B" ->RF Portal Data Link "B". 3. RF Portal Data Link "A" -> RF Portal Data Link "B" (Looped Using A 680ohm Resistor). I appreciate your time to reply. Best Regards Zemme
