It will go into tamper yes. Consider its age and look at upgrading

No sorry they can be inverted Trigger Levels [4] The three inputs (IP1 to IP3), and the inhibit input (INH), can be individually programmed as active high (+ve trigger) or active low (-ve trigger). An active high input will trigger the Informa when the voltage present at the input exceeds 3.5V (maximum is 15V). An active low input will trigger the Informa when the voltage is less than 1.0V. a) Press [4] to change the Trigger levels. The 4 LED’s show the trigger level of inputs 1 to 3, and the inhibit input, respectively. A lit LED shows that the input is programmed as active high. b) Press keys 1 to 4 to toggle (switch) the trigger level of the inputs, between active high (+ve trigger) and active low (-ve trigger). c) Press [PLAY] when finished, or [QUIT] to ignore any changes. The Informa automatically resets to top level of the Engineering controls

Isnt there a jumper for trigger polarity?

Has this started happening recently? ie did it used to work. What exchange are you connected to and are you aware of BT pstn switch off? Sorry just read the OP Id assume you have your triggers wrong way around

Agreed that was my thought. Does texecom have a 30 second comms timer by defaultl?

How long have you left it in alarm before silencing?

Was using a real example of what trades cost, if it was security related it would be a 'rip off'

Agreed

Agreed I know we talk about cost etc but ive just spent £220 on having a plumber tell me my soak away is knackered. There was 2 of em for 2 hours and a jetting machine

I'm afraid ID is long dead. Castle, risco and texecom had modules but the biscuits are long obsolete. Like coal for a gas fire

Thanks for the follow up, as few of us would disable the option it's not something we would know without referring to the manual. Though it was * turns out to be #

You add or remove a star in the users menu for engineer I wouldn't say the afd was suitable. Completion cert would be a better place but yes the author action method isn't defined

Yes but it's a requirement to have user Auth for eng access so turn off with caution

Yes they did the famous zone omit module. Used by us all till software replaced it

use a link to disable the circuit following the shunt lock, no need for a zom

i read it as 2 part sets

No not on the dimension you might look at groups instead

Lol Trebling up on the strobe pos H?

Agreed but that's more than 3. Most complicated is a multi switch '3 core' granted the earth makes 4 Plus sabs used to be 6 core its only the market that commened up hold off and strobe pos

The regs have changed over the decades, a latching strobe is deemed a 'lockout' risk, ie if the strobe is active its probable the system has locked out and won't activate again.

As above if it 22 yrs old you might be able to resurrect some of it but I'd question faith in something so old with unknown service history.

Depends on your mindset, do you want maybe say 90% reliability or less. If less your going the right way look at generally available diy ring etc. Will work via the school WiFi. You could go as you say for 1 way rf door bells or even 1 way rf security stuff. But the bigger question is do you need it to be resilient, something to rely on?

I know this will offend the sparks but alarm lads deal with even numbers of wires. Its a different skill set with much smaller cables. I've yet to meet a spark that didn't know better / best in every way till the first series contact came up

Why not buy a non ADT badged (and modified) visonic unit?

As above many panels can but you need to consider holidays etc. Maybe a panel with remote arm disarm would be more suitable
