Small scale manufacture pre 1970's would probably be on breadboard ? There are chunky but modern looking resistors & capitors. All components are marked in white text along Co. Name & model no.. Use of slotted screws say built up without power tools A 4x4 box is very heavy duty or predated the plastic alarm cased detection of the 1980's ? I've never seen one before or heard of the co But item would have probably been in warehouse or similar & probably quite pricey in it's day

Looks 1970s to me ?

I assumed spam, but looks like good info

Do they have JD Weatherspoons?

Off thier tits on Halal Carlsberg ?

The president of Iran dead wrapped in a blanket- The bloke from verisure still appears to be trying to sign him up ?

Congratulations on being our latest alarm expert & welcome to the moderation team....

As I understand it a a switch mode power supply switches on & off this is what I assume you are seeing on a scope ? Texecom has been around nearly 40 yr & turn over nearly 40 million, My stuff works, yours system despite your test equipment & qualifications doesn't ?

Sorry I disagree- I've never had any reason to use an oscilloscope on an intruder alarm nor do I need a £500+ multi meter (it would only get lost or broken out in alarm land) Aged 17 or so I knew something like a 9600 required a power supply to run all 16 zones & multiple keypads & speakers Who would have guessed more than 30 years later I'd still be having conversations with people who don't understand the basics principles, Suitable current in day & alarm, suitable voltage at each device when running off the battery, if you've not got this you'll have problems Your alarm appear to have lots of problems I've got lots of alarms with very few problems, its funny old world isn't it ?

Me? I think there horrid things to work with- I had to ring risco the other week to find out how to toggle the channels to test a dualcom Beyond paying me to stand there in person & press buttons whilst swearing at the alarm until it works the only support I can offer is moral support.... @naeem7861 you can do it son ! The full manual is online, if you don't do alarms it probably makes more sense as I have a preconceived idea of how things should work & this is an Israeli product targeted at North America ?

25+ year old cables, 20year old expanders, cable length, water in man holes, length of time its measured ? its not a problem site,, so never tried to fixe it.

I would normally wire intruder alarm data in belden, daisy chained, screened to cabinet (normally 4mm machine screw & nut, floating at last device

spikes killed them, I've done PE24's between Edinburgh & London this yeat & don't go back I also do Euro's & Orisec & don't have ay real issues with anything. Al doesn't do Texecom using more exclusive equipment...

- PE 168, now much smaller system than it was for 20 years as a P168, each building has at least 1 psu, cables run under the public roads

Every possible measurement needed to commission and diagnose an intruder alarm can be done with multimeter If you have property large enough to need 5 expanders & lots of expensive test equipment I would assume some with your qualifications & talent could earn more more doing your own job & pay a proper alarm co. to provide a working complaint system rather faff around wasting time & money doing it poorly.

As I understand it the PSU comes from Elmdene, when they failed they just stopped producing voltage. Compare it the ones o your the PSU2000XP's ?

I've got lots of it in the field, the oldest premiers are over 20 odd years, But the 2.5A of power is at 12v ? Chances are 5 extensions speakers will be almost all the current of the system !

Roughly speaking the controls will power- Its self & some detection devices 1 external sounder 1 keypad 1 extension speaker 1 communicator Maybe a 2nd keypad or an expander with mostly contacts on it It will probably need a 9ah battery to have the correct amount of standbay time

That's nice... did you read the installation book where it states the size of the psu & the current drawn by each texecom device ? You have the main board, 5 expanders, 5 speakers & a keypad I also assume you have an external bell(s) & powered detection All powered by the panel....

normally closed put 1 wire off the circuit on the terminal with the red wire & the other on ther terminal with the black wire

neither the controls or the button are something we'd see in the UK one circuit wire into the left terminal, alarm value resistor across both the device terminals, a tamper value resistor the right terminal, 2nd circuit wire soldiered on other side of the tamper resistor this would be double end of line resistors, you product or market place may do this differently...

The bell should ring as soon as the power is removed regardless of whether its on day or engineering mode If the alarm is old, diy or fitted by a muppet, it might or it might not ??

Invert the 2 negative output? Or Use relays from the neg outputs? Use a relay board on the Stu outputs if it's a 48? Add an expander with 8 outputs? Whatever works for you ?

It a euro 46 with 76 zones as far as I'm the 46 did more than 46 zones ? It might have done 76 but I would have to look at the book... There is a plastic hybrid panel with built in radio coming... For the last couple of years ? Does the 280 do the app ?
