View Full Version : New Install - EOL, Wireless, GSM?

Hi,
I'm about to install my own alarm and have a few questions! I'm an electronics technician by training but the last alarm I installed was a long time ago - before EOL resistors and wireless sensors were commonplace - and before there were any real standards in place. I just want to be sure I'm doing things right so please bear with me.

1) EOL, NEOL, SEOL, DEOL. Which to use in a domestic setting? (I'm leaning towards SEOL as it seems to be a compromise between NEOL and DEOL and seems to only require one resistor placed at the end of the zone loop)... Where (physically) would this resistor go? (i.e. is there a place to screw it in in the sensor/contact or is it simply soldered in series in the zone wire - and if so, what's the best practice to protect and insulate it?).A picture would be great...

2) I want to go wireless for some zones and have already got a panel that will support this - Europlex Signet 200. Do I have to buy their brand wireless devices or can I mix n' match w' other manufacturers?

3) At times I'd like to be able to bypass the built in reed switch in certain wireless shock sensors (e.g. to leave a window open for ventilation, yet arm it to sense shock), however what I'm hearing is that because the shock and reed are tied to the same zone on a wireless system, that disabling one (e.g. the reed, by force arming) will also disable the shock. Is there a solution for this?

4) Although this will be mostly wireless, there will still be some wiring needed for the keypad, PIRs, one or two hardwired contacts etc. Below are the possible wiring circuits as I see them: Is there a standard wire colour and gauge to use? AND should a heavier gauge be used to drive the SABB?

Entry/Exit
Panic
Tamper
Fire
Alarm zone
Inertia loop
Aux Power, + & - (for PIRs etc)
Control panel to keypad
Control panel to SABB

4a) Will the shock sensors w' built in reed contacts and tamper loops need 3 core or is it acceptable to wire the tampers to the contact loop and use 2 core?

5) I see there's a GSM option specifically for my panel. I'm tempted but at EUR300 it's over twice the price of the panel (!) Are there any other less expensive GSM options?

5a) For the GSM, I'd want to use a pay as you go (top-up) SIM and ideally have it notify me by text if it's top up balance gets low (I've seen this function on a Jablotron GD-06 card but that won't interface neatly into my SigNET panel). However, if this isn't an option how would I check the balance on the SIM other than removing it and placing it into a mobile? Any recommendations on which service provider to go with for the SIM?

Thanks for any and all info - or any other tips any one has on wire runs etc...

Using single EOL technically the resistor can go anywhere wired in series in the loop ideally it should be at the end on the loop at the last sensor or contact where there is only a single cable.Depending on the sensor used there should be spare terminals to wire in & out of the resistor


2) I want to go wireless for some zones and have already got a panel that will support this - Europlex Signet 200. Do I have to buy their brand wireless devices or can I mix n' match w' other manufacturers?Stick to that brand


3) At times I'd like to be able to bypass the built in reed switch in certain wireless shock sensors (e.g. to leave a window open for ventilation, yet arm it to sense shock), however what I'm hearing is that because the shock and reed are tied to the same zone on a wireless system, that disabling one (e.g. the reed, by force arming) will also disable the shock. Is there a solution for this?
Not by any commands on the keypad. Some wireless brands have a link inside the device to enable or disable the reed. For regular use the only solution is to install seperate sensors & contacts


4) Although this will be mostly wireless, there will still be some wiring needed for the keypad, PIRs, one or two hardwired contacts etc. Below are the possible wiring circuits as I see them: Is there a standard wire colour and gauge to use? AND should a heavier gauge be used to drive the SABB?

Entry/Exit
Panic
Tamper
Fire
Alarm zone
Inertia loop
Aux Power, + & - (for PIRs etc)
Control panel to keypad
Control panel to SABB
Heavier cable would not be required unless cable runs were over 100m long colours used are entirley at your discretion

4a) Will the shock sensors w' built in reed contacts and tamper loops need 3 core or is it acceptable to wire the tampers to the contact loop and use 2 core? If as you stated above you are using single EOL then you use 4 cores. 2 for the zone (with single EOL resistor in series) & 2 for the tamper wired to the aux tamper at the panel


5) I see there's a GSM option specifically for my panel. I'm tempted but at EUR300 it's over twice the price of the panel (!) Are there any other less expensive GSM options?
€300 is probobly as cheap as you will get. Generic ones tend to be a bit dearer actually


5a) For the GSM, I'd want to use a pay as you go (top-up) SIM and ideally have it notify me by text if it's top up balance gets low (I've seen this function on a Jablotron GD-06 card but that won't interface neatly into my SigNET panel). However, if this isn't an option how would I check the balance on the SIM other than removing it and placing it into a mobile? Any recommendations on which service provider to go with for the SIM? With most GSM units removing the sim is not ideal as the system has to be powered down & powered up again to find the sim. Using Vodafone you could check your balance & top up online or at ATM. I don't know of any that will notify you when credit is low.


Thanks for any and all info -... Your welcome. Hope this helps :)

Back again with a question related to the previous. I need to wire several contacts to the same zone and have a question re EOL wiring:

Can I have more than one (NC) sensor per zone loop if I am using DEOL? (I seem to recall reading somewhere that this was either not "to code" or not technically feasible without the use of special sensors.)

What about doing so on an SEOL loop?

This diagram shows how to wire sensors in series with duel EOL

Thanks, FYI I had to log in to see/download that gif.

Also, I remember now where I saw the code issue about several wiring sensors to a single DEOL zone: Doing so would void a U.L. (U.S.A.) grading...

Its fine for EN50131
Commercial installations require single zone for each Inertia
