I'm not sure the company still exists, I'm trying my luck by trying to find old directors/engineers from the late 1990s on LinkedIn! Nothing yet though...

A bit of a long reach this one, but I'm trying to 'emulate' a keypad for a Scantronic 8136 panel. I've got as far as identifying it using a 150bit protocol of what seems to be long and short pulses on the signal wire done through releasing the signal wire from ground and letting the panel pull...

ok, done using ESPHome, 2 relays, 2 inputs Keyswitch on zone 13 (relay) Normal alarm on zone 14 (relay) OP3 configured to latch when alarm active OP4 configured to latch when alarm set I found a new document called Installation and Programming Guide for the 8136UK-50/75 which helped...

Thanks, what is the A/T 1 connection in your picture?

Typing my alarm code in during this process performs an unset..confusing!

Bit of progress, if I set the zone to KF rather than KM. Then completing the circuit on the zone now puts the alarm (Level A) into a kind of set mode, but the sounder maintains a steady tone, and it never completes the set.

Thanks, my model is 8136 which doesn't have this bit in the manual. The KM doesn't seem to exist in an area (see the photo above where I configure the zone). however, I do have a keyzone setting on the levels now (I think this is new). See attached :)

U00:A03:RESET U00:A02:RESET U00:OFF SITE Is the latest in the log for today when I touched the wires. Alarm zone 1 on the main board.

This is how it looks on the keypad when configuring zone 1. I'm simply connecting the circuit together using a wire between the two terminals to simulate a key switch/relay

Yup. Problem is though, my alarm system doesn't seem to do anything when the zone in in KM mode, and I open/close the zone circuit.

Yes. So it seems that I can configure a zone as a KM which I (google) interpret as Keyswitch Momentary. So If I close/open a circuit on the zone configured as KM, I would expect the alarm to set/unset (assuming no alarms, errors etc). Does that seem right?

Hi, I'm trying to make a Scantronic alarm a bit smarter, and wonder if there is a zone type that would support setting/unsetting the alarm via a zone (rather than via the keypad). I believe there is some kind of key switch (KM zone type?) that is possibly compatible, but ideally I just want to...
