Hi all,
I am looking to have a house alarm installed (everything was pre-wired with 4-core security cable during a recent renovation / extension). Trying to decide between SP5500 and MG5050. The configuration I am after comes pretty much at the same overall cost, MG5050 option ends up approx $75 more expensive (incl gst). Various installers gave me a price but they have no interest in explaining some of the features and what functionality I can get and what not, I believe is because most of them would not have any idea about these issues I am raising as they a bit above the average client they come across?...
The number of PGMs available is important for me, the SP5500 option includes a PGM4 module (which gives me 6x PGMs in total) and the MG5050 option has 4x PGMs built-in.
I am looking at both options as I wanted more PGMs than the 2x on the SP5500 PCB, the intention being to have garage door and actuated gate + exterior lights (landscaping) on the other PGMs. The garage door and the gate will also be controlled from the remotes REM15. The rest of the PGMs will only be controlled from a touch screen TM50, I foresee to have a decent "wow" factor when activating the landscape lights from the touch screen... The TM50 is also included in both configurations.
Both options also include wireless connectivity and 2x remotes REM15 plus internet connectivity and the 3 yr subscription to have this working. So I am confident both options would do pretty much the same apart from the different number of PGMs (I get 6x PGMs with the SP5500 + PGM4 option, which is also marginally lower cost).
QUESTION 1:
is it worth going for MG5050 (more expensive and gives me only 4x PGMs)? Any reason to opt for this one over the SP5500?
They will both have wireless (MG5050 has it built-in) so they will both accept wireless sensors in the future if I want to expand the system. Is this a wrong assumption?
QUESTION 2:
from what I can see in the manuals, there is only one siren output on the PCB? My configuration includes 3x internal sirens and of course, one external. Plus 6x PIR sensors (1x in garage + 4x ground floor + 1x on first floor). In case any sensor is triggered I assume all sirens go off at once?
Is it possible to have sirens and sensors grouped somehow, so let's say when the garage sensor goes off then only the siren in the garage is activated, if a sensor on ground floor is activated only the siren on ground floor is activated, and so on? Of course, the external siren is active when any internal siren is active.
QUESTION 3:
I will also have 3x smoke sensors (garage / ground floor / first floor). I guess I can get an email when one of them is activated, so that's OK. But I am unclear if the sirens are activated when a smoke detector is triggered? That would be a real nuisance. The preference would be the sirens are NOT activated because of the smoke sensors. Generally, a smoke sensor would go off when you are actually home and it would be because of cooking...
QUESTION 4:
the manual for TM50 and all pictures on internet refer to the option to connect an exterior temperature sensor and have outside temp permanently displayed on the screen. The internal temp will be displayed anyway, as the TM50 apparently has a built-in temp sensor. The problem is that all suppliers I contacted never heard of this option and on Paradox website this part (TEMP07) is shown as being discontinued! But the TM50s are still manufactured and advertised as capable to display outside temp using the optional TEMP07. I believe I came across somewhere (but I cannot remember where), with a confirmation that this sensor is nothing else than a standard NTC 10k temperature probe ($4 on Trade Me, for example). Does anyone have any experience in adding the temp sensor to the TM50 panel? Is it indeed an NTC 10k suitable (and accurate)? Websites in USA and Europe still sell this part number and apparently each comes with a label attached showing a "calibration factor" which needs to be entered into the TM50 interface?... Unfortunately the NTC 10k sensors do not appear to come with such "calibration factor"... and the sensors from these companies cost 15 - 25 USD + $30 postage to NZ...
Many thanks in advance for your advice.
