Texecom PIR tamper wiring?

[JOEPRO]

This is a specific query and posted in a new thread as some may not be looking at the other alarm thread.

My query is relating to the tamper switch wiring on a Texecom or other alarm system.

My existing alarm which was pro installed 20 years ago had 6 core wires to each PIR. Inside the PIRs the blue and white wires were connected up. But at the control panel these blue and white wires were cut short and twisted together.

I wired up my new replacement Texecom PIRs to match the existing ones using the same blue and white wires.

Old:



New Texecom:



However my Texecom Premier Elite 24 panel also doesn't appear to have provision to connect the blue and white tamper wires!

Is it a case that I should leave these disconnected as only certain systems would support the tamper switch back to main panel?

Thinking about it anti tamper on a PIR in a residential installation is probably not required. Unlike a public buiding there should be no risk of access for someone disabling a sensor. And when armed they won't get to the sensor before the system is alarmed anyway.

This is what my new board looks like:



I don't see any provision for the individual tamper switches.

As an aside the new PIRs do have inbuilt resistors on junpers which may be some form of alternative wiring but even so I'm not sure if this is even really required in a domestic alarm.

Looks like #11 supports a tamper loop.
I think you will need to daisy-chain all the tamper loops into series if you want more than one sensor tamper protected.

As above, the tamper loop is just that a loop through all the detectors, bell box, ect.
So would only have two wires left (one white one blue) by series connection of all devices at the panel.

Thanks all that confirms what I was thinking then.

In order to ensure the best connections possible to avoid future false tamper alarms I will solder and heat shrink the PIR tamper wires in a daisy chain and terminate them at the aux tamper terminals. So if any one of the tamper switches breaks the circuit the board will see open circuit and trigger.

dont even bother conectting them at the pir s who the hell on earth is even going to get in without setting the alarm off and cutting the wire just link the tamper output at pannel

I have them all connected at the PIRs already. What threw me off was the prior installer had them all connected at the PIRs.

But then he had also wrapped them all together in one bunch at the back of the old board and twisted all whites and all blues together. (I took the old board apart after I had installed the new PIRs) That makes no sense at all does it!! He should have just left them snipped off if not going to follow through and make them functional.

The only thing that makes me want to leave them is that the risk of a false alarm is probably higher than someone actually tampering with any of them before they are triggered which is basically impossible isn't it.

the only one that realy needs to be covered is the out side bell box as if they remove that the box in side is the only thing that will go off unless it has a dialer

if they get in the property befoe they try to tamper with the pirs or door contacts it should be going off

that is unless any one has accress to the property before hand what is why realy they have tamper connections so nothing can be played with while the alarm is unset
