aritech alarm faulty sensor

westside99

hi guys,
i have an aritech alarm system with 4 infra red sensors and one contact sensor,
my problem is for the last month or so the same zone has been going off,
(last time yesterday morning at 5 am , delighted i was !! never mind the poor neighbours )

anyhow i rang the supplier (nightguard in galway) the guy on the phone was nice and helpful, but its an old system and he couldnt remember how to put that sensor into soak as he called it, but if i wanted to get a tech from his company around (€140) he's sure they could sort it>

so my question is does anyone have any knowledge or cures for me?
any help would be great .

i have the password to access the control panel to get at the eng logs etc

thks in advance

The sensor on that zone is more than likely faulty. If you go into the zone menu, then into zone attributes it is in there. If the sensor is as old as the system I would just get a replacement sensor.

i've never replaced a pir before
* is there much to it ?
* are they interchangable

The connections on them all are pretty much the same.
Make a note of the colours for the connections before you disconnect the old one, then connect the new one in the same way. Always ensure not to short the + power (Nearly always red) off any other cores.

There is not much to changing the pir. The only issue would be the power in case you blow the fuse. It is easy to change as you will be using the same colours for the pir.

ok i've managed to get my hands on a aritech sensor ( newer than the one thats there)

on the old sensor i have 4 wires and two resistors
red going to the +
black going to the -
then there are two terminals joined listed N.C.
green wire to the N , and coming from N one resitor to C
the second resistor from C to tamper terminal
and finally the white wire to tamper


now the new sensor has 7 terminals

from 1 to 7 theres a wire joining them
1 has -0v
2 has 12v+
3 and 4 alarm
5 and 6 is tamper
7 has LED

3,4 5,6 and 7 also has circuit kinda stuff on diagram to not sure whats its about


so if any of this makes and sense to anyone
help please !!!

Wire as follows

1 has -0v

---

Black
2 has 12v+

---

Red
3 Green & 1st Leg of a resistor
4 2 nd leg of resistor & 1st leg of another resistor
5 2nd leg of remaining resistor
6 White
7 Not needed Leave empty

Hope this makes sense. If not let me know & I'll draw up a diagram.

hi there,
need some help, i just changed a sensor as per above, forgot to turn off the power though. so what happened is the fuse in the main mother board upstarirs blew, so i've replaced this but the key pad down stairs doesnt appear to work now and the alarm is going off !! any help?

From the sounds of it you have blown the fuse going to the keypad.
Do you know which Aritech system you have installed ?
Some have a diagram on the rear of the lid of the control panel which will indicate the fuse locations and the function of each fuse.
