Unusual ADT Intruder Alarm System

Here’s a system I found in a bin. It consisted of a Honeywell Galaxy 2 Series, a MK7 (maybe MK6?) Keypad, C&K Systems DT400 Series Dual-Techs, Securis D20 M PIRs, Alarmcom IR160 PIRs, a Knight Plastics 16ohm Extension Speaker and an ADT ‘Hex’ cover complete with an old Scantronic Eurobell (Model 8505/8506) underneath!

Presumably it was a system originally installed by Modern Security Systems and when ADT bought Modern, they changed the panel and keypad for newer versions and replaced the Modern cover with an ADT one instead of replacing the whole bell box.

The Galaxy 2-20 didn’t work and I hadn’t cleaned up the PIRs when I filmed the system so I just had an Alarmcom IR220B wired up as well (they were also used by Modern Security Systems)

This sort of setup was seen in a video I filmed a couple of years ago, in which a Eurobell with an ADT cover was ringing. There’s a slight chance it’s the exact same box and it was replaced, however the fading on the ADT covers look different, so I doubt it.

Thanks for watching.
