How to fix Premier Alarm Power Supply (PSU) fault
If you get a fault message on your Premier alarm that says ‘Power O/P fault System 12V’ then it’s telling you that you’ve had a problem with your Power Supply – which is normally related to the mains power being down (for example if you’re had a power cut or a fuse has tripped). In this case all you need to do is to restore mains power (and ideally also check the fuses whilst you’re at it).
To remove the ‘Power O/P fault System 12V’ message from your Premier alarm display, then the first thing you should do is to ENTER your 4 digit code and press RESET. This should then return your system to its normal working state, meaning you’ll be able to operate your alarm as usual.
Having done this, if the ‘Power O/P’ message is still showing then you probably have a bigger problem with your Premier alarm PSU (power supply unit).
At this point you can either try to fix the problem yourself (in which case read on) or book an professional engineer to fix (via our engineer service here >>)
From experience we’ve experienced scenarios where even though we’ve restored the mains power and done a reset (as above), the Power O/P alert still shows. In this case you essentially have two options (both of which require a little more knowledge / skill to execute properly)
- You may try to restart your panel by powering down for 1 min and power up. Don’t forget to reprogram date&time.
- Having powered down the alarm, if the O/P fault is still showing you may want to replace power supply unit (PSU). This is fairly easy procedure to do, but you need to cautious about making sure you disconnect all 240V mains supply to the alarm. The instructions to do this are listed below.
