I have recently moved into a new house with a Pyronix 46 V10 system, but I only have the engine code and not the master.

I have attempted to move a PIR to install coving, but now the alarm is sounding but I don’t know how to stop or reset.

Help!!

Engineer code will stop the tamper when system is in day?

The master can be changed via the engineer menu?

Have you had time to fix it?

On the Pyronix Enforcer / PCX 46 V10 panel, having the Engineer code gives you complete supervisory control, so you do not need to crash the panel or short any NVM pins to reset the Master code.

A few practical steps to resolve the Master code and clear the PIR tamper cleanly:

1. ##REMOVED##

2. Handling the Wireless / Wired PIR Tamper
If the PIR is a wireless KX12DQ-WE / KX10DP-WE, opening the casing trips the rear spring tamper and keypad sounder. While the panel is in Engineer mode, all global tampers (casing, lid, bell box) are suppressed in software. Move the sensor, fix your backplate firmly to the masonry (ensuring the rear tamper break-out peg rests flush against a flat wall surface without flexing), clip the front housing back on tightly until the bottom screw engages, and only then exit Engineer mode. If the tamper peg isn't fully depressed, the panel will alert immediately upon exiting Engineer mode.

3. Set Time and Date
Once you exit Engineer mode using the Master Manager code, check the panel clock (Master Manager menu -> Set Date & Time). If the internal battery drained during power-down or moving, having an accurate clock prevents false battery fault logs.

Once User 01 is changed, you can set and unset daily using your new master PIN while keeping your engineer code safely documented for future maintenance.

A few practical steps to resolve the Master code and clear the PIR tamper cleanly:

1. Changing the Master Manager Code via Engineer Menu
Log into Engineer mode on the keypad (default is typically 9999 or your current engineer PIN). Press NO until you reach 'CHANGE CODES?', then press YES. Press NO to scroll past 'Change Engineer Code' until you see 'Change User Codes?'. Press YES, select User 01 (which is the Master Manager), press YES, and enter your new 4-digit master code. Confirm it, then press NO until you reach 'EXIT ENGINEER MENU?' and press YES to re-arm the tamper detection cleanly.

This is incorrect beware when following

Spot on to pull that up Barsnake and MrHappy—fair challenge and good catch on Pyronix panel hierarchy.

I was conflating the Texecom/Galaxy engineer user code allocation menu with the Pyronix Euro/PCX architecture. On the Pyronix PCX 46 / Enforcer V10, the Engineer menu deliberately sandboxes user privacy: the engineer cannot directly overwrite or view the Master Manager PIN inside 'CHANGE CODES?' (which strictly handles the Engineer PIN).

If you have moved in with an unknown Master code on a PCX 46 V10, here is the proper field procedure without losing your programmed zones or wireless devices:

1. Silencing the Active Tamper:
Entering the 4-digit Engineer PIN immediately silences the internal/external sounders and drops the panel into 'ENGINEER MODE'. While in Engineer mode, all peripheral case tampers (PIR, bell, and panel lid) are inhibited in software, giving you breathing room to secure the PIR to the wall.

2. ##REMOVED##

3. Clearing the PIR Tamper:
Make sure the rear wall tamper microswitch / breakout spring peg on the relocated PIR is firmly compressed flat against the coving/masonry. If the casing is distorted or the screw isn't tight, as soon as you press NO until 'EXIT ENGINEER MENU?' and press YES, the panel will trip tamper immediately.

Once back in Day mode, you can log straight into the Master Manager menu using 1234 to program your own household PIN.

Having installed and maintained Pyronix Euro 46 and Enforcer panels for years, having the Engineer code actually makes this very straightforward to solve without needing an installer call-out:

1. Silencing the Tamper Sounder
- Walk up to the keypad and enter your Engineer Code followed by [YES] (or green tick).
- Entering the Engineer code immediately silences both the external bell and internal sounder. The display will enter Engineer Mode and show the specific circuit causing the tamper (e.g. Input 02 Tamper or Case Tamper).

2. Fixing the Physical Tamper on the Moved PIR
When moving a Pyronix PIR (such as a KX12/15 series) to install coving, 90% of tampers are caused by the rear wall-tamper plate:
- Pyronix detectors feature a dual-action tamper: the front casing microswitch and a spring-loaded plastic breakaway foot on the rear that rests against the flat plaster.
- If the detector was unscrewed or angled downwards to clear the coving, that rear tamper plunger expands outward and triggers an open circuit.
- Check that the base plate is screwed flat against solid masonry/timber, ensure the spring plunger is compressed, and make sure the front plastic cover hooks into the top catches before driving the bottom locking screw home.

3. Setting a New Master User Code via the Engineer Menu
Since you have Engineer access, you do not need the old master code to change it:
1. In the Engineer menu, press [NO] repeatedly until the screen displays CHANGE CODES?.
2. Press [YES].
3. Press [YES] on USER CODES?.
4. The screen will display User 01 (User 01 is assigned as the Master / Manager by default). Press [YES].
5. It will prompt ENTER CODE: type in your desired new 4-digit Master code and press [YES].
6. Set the user type to Master (or Manager) and assign standard Area permissions (usually Area A or All Areas), pressing [YES] to confirm each prompt.
7. Press [NO] until you return to the main menu.

4. Exiting Engineer Mode Back to Normal DAY State
- Press [NO] until the keypad asks EXIT ENGINEER MENU?.
- Press [YES].
- If the PIR tamper is properly seated and closed, the panel will sound a confirmation chime and return to normal DAY mode (displaying time/date and System Disarmed).
- Note: If the panel beeps error tones and says Tamper Fault Pending, do not force an exit—the physical microswitch on that PIR is still uncompressed or the wiring is trapped behind the bracket.
