The most common Pyronix Euro 46 alarm problems

Pyronix are a fairly robust manufacturer of alarms, and if you’ve got a wired version of their system then you’re likely to have had few problems over the years. The great news is that these types of alarm system can last for years, and importantly if its wired then can also be easily updated – for example adding smart technology functionality or adding new / different sensors.

Tips on fixing your Pyronix alarm

Although alarm systems are fairly simple, when errors occur it can be quite complex fixing them if you’re not trained / don’t know what you’re doing. For example, if you do try to fix your alarm yourself you need to be aware that

– Once you open the alarm panel without the engineers code (which you won’t have and will in general be specific to the alarm engineer who installed your system) then the alarm will ‘go off’ (i.e. make a loud racket!)

– Opening the alarm panel lid, you’ll see inside your alarm is a hornet’s nest of wires – amongst which is an alarm battery

– One of the most common alarm problems are to do with battery faults – with alarm batteries lasting 4 to 5 years on average, and older alarm batteries causing problems to the alarm beyond power failure problems when there’s a power cut.  It’s important to understand though that replacing your alarm battery can be tricky – as the battery will be surrounded by the mess of alarm cables, and there’s a risk of either you dislodging a wire (causing a fault) or getting an electric shock (fro the 240V power).

If you need help with your Pyronix alarm battery fault, watch the following video as a help guide

Pyronix alarm engineer reset

Pyronix alarm systems are programmed to have an ‘engineer reset’ as standard on most of their alarm systems, meaning that if you open the alarm panel box (i.e. unscrew the x2 screws and take off the lid) then the system won’t let you use it again until you get an engineer reset code.

The reason why Pyronix alarm have ‘engineer reset’ codes programmed as standard is to stop people from tampering with the alarm – inside. It’s not possible to stop someone unscrewing the x2 screws, however it is possible to programme the system to ‘lock the user out’ – which is what the engineer reset code is all about.

If you need a Pyronix engineer reset, you can get in touch with our team (here) and we can organise for an engineer to visit and default / reprogramme your alarm system for you – at the same time we can also remove the engineer reset code, so you don’t need to rely on an engineer in the future.

Or if you want to try an engineer reset on the Pyronix Euro 46 yourself, here’s the steps:

  • Open up the panel and take off battery lead
  • Remove TR from terminal
  • Take off mains power to down power the panel and then reapply mains power
  • The alarm will trigger
  • Go to the keypad and hold yes for 30 seconds
  • The alarm will stop and you should be in the engineer menu, and then reprogramme as you like

As mentioned, the engineer reset process for the Pyronix is quite complicated and requires dealing with 240V – so we’d generally recommend getting an engineer to help you as you can end up doing damage to the alarm and yourself.
