My Daughter bought a house last year that has this panel and PIRs (18 months old). The installers engineer upset her when he did the handover and she doesn't want them back.

First question: They came out and changed the Engineer code 10 days ago and she asked him to set it to a number which is the same as her user code:(. After he left she discovered she could not set the alarm as when she put her user code in it switched to engineer mode. Managed to get a panel installation manual out of Texecom and on Saturday changed the Engineer code again but that also appeared to reset her user code so we changed the user code back to the original. Alarm now seems to be working properly (she can set and unset) but is it going to bite?

Second question: She is getting two cats and we have bought some replacement pet PIRs which I expected to be a straight swop, the sensors are Texecom Premier Compact PW (ACH-0001, H/W rev 9, F/W 1.0.1.1) I expected these to be a straight swop. The box helpfull has a code which takes you to the manual on line but you need to be a registered installer to get access.

The PIR that is fitted is a texecom unit IMG_0223.JPG the first I took the cover off is like this. Looks like EOL wiring but the jumpers on the left are not marked . . . . Have not taken the other three covers off yet, thought I would seek advice from the learned gents on here before I do something that could screw it up.

I have not done a walk test but will check if each PIR is on its own zone as I expect them to be.

Now the new sensor has more jumpers - 2 sets of 4 on the left marked "Alarm" and "Tamper" (e.g. alarm marked 4k7, 1k0, 6k8, 5k6 which look very much to me like resistances of which I select one.) Two jumpers on the right are LED on and pulse which I expect to leave as is. And it has seven terminals instead of six! The seventh marked IRLED. I thought the panel instructions would give some guidance but not a lot - 1/2 page in 150 ish.

Now I assume (and that is what I am checking) that the 0/12v are straight swop as are alarm (1 connection) and tamper (1 connection) but how do I work out how to set the jumpers for resistance if I can't tell how the current sensor is set?

Third question: The pet PIR box states "selecting PER mode adjusts the digital signal processing algorithms to increase animal immunity up to 35kgs" is this the "Pulse" Jumper and does it need to be PC1 or PC2 for pet

Third question: why the f... didn't he fit a Veritas, it is only a four bedroom house! OK - you don't know either :).
 
Texecom resistance 4k7 alarm 2k2 tamper, straight swap 12v 0v alarm pair, leave pulse jumper default. I’m sure you will get a more in-depth answer to other points from another user
 
You can’t have the engineer code same as the user code ...
Texecom pet detectors are rubbish ....Bosch or optex rx40 pt would have been better
And answer to your last question ....maybe the system was fitted as a graded system ....the veritas isn’t ...
 
Thanks for the assistance.

I thought that would be the case with the codes but didn’t think to tell her before the engineer called and he didn’t check with her. They are different now.

Will see how the Veritas PIRs go, she is getting rag dolls so they grow up to be pretty big cats!
 
Pet sensors will need to be in the correct postions.
Any sensor looking at stairs or kitchen worktops etc could be a big issue.It is not just a case of swapping the existing sensor for a pet sensor,these my need to be repositioned.
