![]() I only have user / manager passcodes and not the engineer’s passcode and hence cannot configure the RIO. I also cannot see it in the ‘Omit Zones’ Menu. However, the RIO now indicates (via the PCB LED) that it is not configured and although the Sensor LEDs blink red on confirmed detection, I have confirmed that they do not trigger the tamper or intruder alarms (wired as Double Balance). ![]() This seems reasonable after spreadsheeting the power consumption of each end device. After some investigation, I found that approximately half of the I/O was connected directly to the main Galaxy board and the other half is connected to a RIO. I have subsequently bought and replaced the PSU with a like-for-like (Elmdene) replacement and also replaced the 2 x back-up batteries as one had failed (<8v) and both were over 6 years old anyway. I have a strong Electronics / Electrical background and decided to 'have a go' myself. I managed to silence / reset the system and the local Alarm Company assessed the damage as an external PSU failure and quoted £250 to complete the job. ![]() However, a few months ago the alarm failed during a thunder and lightning storm. I continued a contract with a local Alarm Company as a matter of course and they 'inspect' the system annually. I have recently inherited a Honeywell Galaxy 2-20 System when I moved into a new house at the start of the year.
